Winchester Model 70 Classic Stainless .300 WSM - Worth Investing In?

I’m looking for some advice from those who have spent a lot of time with the New Haven Model 70 Classics.


I have a Winchester Model 70 Classic Stainless in .300 WSM that was built around 2000. It’s the controlled-round-feed version with the original 24” stainless barrel (1:10 twist) and factory synthetic stock. As far as I know, it’s completely original other than having the factory trigger professionally adjusted years ago. That trigger is honestly one of the best hunting rifle triggers I’ve ever used.


This rifle has quite a bit of sentimental value to me, which is one reason I’m reluctant to move on from it. At the same time, I’ve always felt it was something of a mixed bag.


On one hand, the action is incredibly smooth, the quiet controlled-round-feed design and the trigger is outstanding. Every time I cycle the bolt or dry-fire it, I’m reminded why so many people still love the Model 70.


On the other hand, the factory synthetic stock has always felt unbelievable cheap. It feels Ruger 10/22 cheap, and from what I’ve read, it’s known to flex and provide mediocre bedding. I’ve also been disappointed in the stainless finish. Despite keeping it wiped down with an oil cloth after use, just like the rest of my hunting rifles, it has developed numerous small rust spots on both the barrel and the action over the years. In fact, it’s the rustiest firearm in the gun safe. For comparison, my Remington 870 Wally world duck gun, which has spent years in wet duck blinds and around saltwater, has less surface rust than this rifle. I don’t know if that’s typical of these New Haven stainless rifles or if I simply got an outlier.


Accuracy has also been disappointing. The only load I’ve really spent much time with has been 150-grain Nosler Ballistic Tips, and the rifle has generally been about a 3 MOA gun. I realize I probably haven’t given it a fair chance, as I haven’t done extensive load testing or tried a wide range of bullet weights.


I’ve recently started reading that many .300 WSMs seem to shoot much better with 165-180 grain bullets, and I’ve picked up a box of Federal Premium 180-grain Trophy Bonded Tips to try.


So I’m trying to decide whether this rifle deserves another chance, or whether I’m throwing good money after bad.


My questions are:


  1. Is 3 MOA with 150-grain factory ammunition unusual for one of these rifles?
  2. Before spending money, what would you check first? Action screw torque, barrel channel, bedding, crown, etc.?
  3. Have others seen a dramatic improvement simply by moving from 150-grain bullets to 165-180 grain loads in the .300 WSM?
  4. Is the factory synthetic stock really the primary weakness of these rifles? If so, would you recommend Bell & Carlson, McMillan, or something else?
  5. If this were your rifle, would you invest $400-800 in a stock and bedding job, or put that money toward a newer rifle?

I know today’s rifles generally have better stocks and often deliver better out-of-the-box accuracy. But there’s something about this Model 70 that keeps me from giving up on it. The action, the trigger, and the overall feel remind me what made the Model 70 “The Rifleman’s Rifle.” Before I spend money on a Bell & Carlson or McMillan stock, bedding work, or anything else, I’d love to hear from people who have owned these rifles.


Is there a great rifle hiding inside this one, or should I accept that some of them simply never shot that well?


Thanks in advance!
 
Action screw torque, barrel channel, bedding,

I would check this first since its easy, but also make sure you eliminate the scope and its mounting arrangement as a potential problem. Make sure the center screw is not too tight. For testing purposes, try shooting it with the center screw just finger tight. Make sure the barrel is floating all the way back to the bedding. Make sure the bedding isnt that junky hot glue shit they used for a while that isnt hard at all.

And dont take this the wrong way - do you have other stiff recoiling rifles that you shoot significantly better than this one? You might be part of the problem.

If you like the rifle its certainly worth fixing. Dont pump $400 of ammo down the barrel trying to "find something it likes." Use that money to get it fixed so it likes everything. Good rifles arent picky. Good scope, properly mounted, action properly bedded, it will either shoot well or it needs a new barrel.

In my experience (limited) new haven build quality was all over the place. I dont think they were ever known for good barrels or super good accuracy.

Your last paragraph sure makes it look like uou copied and AI generated question prompt...
 
I can’t help a ton but can give some encouragement.

I have a M70 Classic SS in 270 that is an absolute hammer. It loves 150gr SSTs, they can shoot.

I have a newish M70 EWSS in 300WM that is extremely picky, I haven’t done a ton of true Rokslide testing but I was regularly getting 2-3” 3 shot groups with everything I tried. Ran some Federal 180gr Barnes and it put 3 in the same hole. Not sure if it will shoot anything else but I have those to Barnes work with at least. I was about ready to give up on the rifle.

This was 180gr SSTs

Thanks for taking the time to write all that. I really appreciate it.


1. Scope and mounts: Good point. The scope is a Weaver Classic 3-9x40 from about the same vintage as the rifle, mounted in basic rings and bases by the reputable gun shop where I bought both. That said, I honestly don’t remember ever ruling the scope out by swapping on a known-good optic. If I can get this rifle shooting, I’m seriously considering updating the scope anyway, so this is probably a good place to start.


2. Center action screw: Thanks for mentioning that. I wasn’t aware the center screw could cause issues if over-tightened. I think I need to quit guessing and finally buy an inch-pound torque wrench.


3. Bedding/barrel float: I haven’t had the action out of the stock in years, so I’m going to pull it apart and inspect everything. I’ll make sure the barrel is actually free floated and see what the factory bedding looks like.


4. Shooter error: No offense taken at all. It’s a fair question. I previously shot Palma, not well, but well enough to compete and had some good shooting coaches. The recoil is significant for sure I wouldn’t real idea of sitting down and going through a box or two. I shoot several other rifles, including magnums, considerably better than this one. My dad has also shot this rifle over the years with similar results, so while I’m sure I can always improve, I don’t think the rifle’s accuracy issues are entirely behind the trigger.


5. Chasing loads: I actually agree with your philosophy. I’d much rather identify and fix a mechanical issue than spend hundreds of dollars trying every factory load on the shelf. I did pick up a box of 180-grain Federal Trophy Bonded Tips because several people have suggested these rifles often prefer heavier bullets, but beyond that I’d rather make sure the rifle itself is right.


6. New Haven quality: That’s kind of where I’m struggling. My brother has a 1951 Model 70 in .30-06. Lord knows how many rounds have been through that rifle, and it has probably killed more animals than I’ll ever see. It’s probably a 1.5-2 MOA rifle on a good day, but it has incredible character and just feels like a quality rifle. My Classic has an outstanding action and trigger, but the stock, the stainless finish, and the accuracy have left me wondering whether I got one of the less impressive New Haven examples. I’m trying to figure out whether there’s a really good rifle hiding in there or whether that’s just wishful thinking.


7. AI: 😂 Guilty. I used AI to help organize my thoughts into something readable. The rifle, the history, and the questions are all real. Left to my own devices, the post would have been about twice as long.


Again, thank you so much!

These are the rounds. I’m gonna try on it.

Nosler Trophy Grade 300 Winchester Short Magnum (WSM) Ammo 180 Grain Nosler AccuBond Bonded Polymer Tip​


Federal Premium 300 Winchester Short Magnum (WSM) Ammo 180 Grain Trophy Bonded Polymer​

 
Ok so I have the same rifle. I chased my a$$ for a while with it trying to shoot 150 grain ballistic tips. Mine loves a heavy bullet. The 168 grain ttsx shot decent but I dont like monos after using them. The 180 accubonds shot very well. I have loaded 185 Berger classic hunters for quite a while and they hammer! I dont shoot it much anymore but I have a picture where it will shoot 5 shots under a nickle. It hammers game too. Just stay off bone and try to avoid the shoulder. I no kidding blew the lungs out of a mule deer at 90 yards. They were strung in the buck brush behind this young buck. Wish I would of took pictures. Never seen anything like it. 5 inch exit hole.

Haven't shot the trophy bonded but I bet you have good luck with the accubond.
 
I have a New Haven stainless M70 in .300WSM that started in a camo synthetic stock with the duratouch finish. I swapped the stock for McMillan swirly. Mine shoots MOA with 175gr LRX and H4350. Killed a couple moose and a bear with tha combo. Like yours, the action is smooth and a pleasure to cycle.

Oh well, this gives me great hope thank you so much! Yes, I’ve only killed Whitetail with it. I took it Elk hunting, but was focused on getting my friend my friend an animal. He was successful, but I was not. Yes it will put down a white tail hard. My previous whitetail hunting used to .243 and a 308 and no comparison. .300 WSM really is too much. Exit wounds are just massive.

Just out of curiosity, do you know when yours was made? According to my Google search, it should’ve been made right around 2000 right when the 300 WSM came out. I definitely fell prey to all those advertisers! Does yours pick up tiny spot rust spots? Nothing that won’t come off with some brass wool, more just annoying as I’ll get it all cleaned up wipe it down with oil put it back in the humidity controlled safe in six months later with there’s more of them!

Boy that’s a good looking gun! I hadn’t really not seen a stock that spoke to me, but I really like yours! And I know McMillan makes good stuff.

Guessing around 2003 or so. Not sure cuz i hydrodipped mine shortly after getting it. I felt like being different

Definitely dont give up on it. Mine has sentimental value. Ill never sell it! They really are fantastic. Never had any kind of issue with it. I did pay a guy local to thread the barrel, do a trigger job, glass bed the action, and install a limbsaver pad. He calls it the accuracy package or something like that. I did all that about 20 years ago though.
 
That’s a good rifle, put up a want add on a few forums and see if you can pick up a better stock.
I like timber on a M70.
If it shoots, get it ceracoated.
 
kind of where I’m struggling


I think you already have this at the front of your mind as the problem based off your comments, which is fine. The barrel might well be the problem. A few things to consider:

1) thats a cheap scope on a stiff kicking rifle you need to eliminate that as a potential source of the problem somehow. Borrow a known definitely good scope from someone, or something like that. I have burned enough money in ammo chasing ghosts to pay for a good scope before.

2) if you can get it under 2 MOA, thats plenty good enough to make solid hits on game out to pretty good range. Dont get hung up chasing more accuracy than you actually need.

3) those stocks are indeed pretty janky and if it has the hot glue bed job, id fix that first just outta principal. Good rife to teach yourself with. Its cheap and relatively easy to do.
 
4. Is the factory synthetic stock really the primary weakness of these rifles? If so, would you recommend Bell & Carlson, McMillan, or something else?
5. If this were your rifle, would you invest $400-800 in a stock and bedding job, or put that money toward a newer rifle?

I too love the model 70 smooth action and 3-position safety. Growing up my dad had one in 338 win mag that just fel so much more refined than my ruger m77. I ended up finding a donor rifle to customize because I wanted a gun like dads but with some modern tweaks. It may be worth it for the emotional connection. I shot my friend's $6-7k custom 7prc on a defiance action the other week and felt pretty good about my Winchester: smoother feeding, bolt lift, and general operation than that rifle for whatever reason.

Cant speak to the rest but: I agree the factory stock sucks and for me it was worth the money to upgrade. I went for a new barrel on mine too as I wanted a different chambering, so I never shot the donor rifle to know how well it performed.

If you want more of a vertical grip option instead of a sporter you should also check out stockys vg (would require new bottom metal) or Pendleton composite stocks.

I have a late 90’s vintage m70 FW classic in 30-06. Mine is blued with wood and the shitty hot glue “bedding”. But it shoots everything great and I’ve killed a pile of critters with it. It doesn’t have a scope on it at the moment but I’ll get back around to it someday. It’s the one rifle I’ve kept over the last 30 years and it’ll go to one of my sons. We’ll have to see which one treats me better as I get older, lol!
