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

[Winchester44]

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...

Post a picture of the rifle. I think I have the same one.

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

And this was 180gr Barnes

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!
