.270 upgrade

[Longleaf]

Put a CarbonSix barrel on there in either a faster twist 270 or 280ai

Unless I missed it, one dude brought it up. How well does it shoot at the moment? If you didn't look at it with a borescope would you still be shooting it?

I had an early 70s 700 in 270 i bought used that would shoot at 100, but then 200 and farther would have a mind of its own. When it got borescoped you could honestly see the rifling worn. I sold it to a buddy wanting to do a build and looked for a tika for an off the shelf simple rifle.

Pack it up, send it off to Jess at JES reboring & for $250ish you could have it opened up to .35 Whelan. All the stopping power you'd ever need, plenty for up to 600yds, factory ammo is available (admittedly not common, but It's there) & mild recoil.

bored to 338 06 or 35 whelen would be cool as an extra rifle, but recoil (when loaded to what the cartridge is capable of) is starting to get up there. Both really cool cartridges that must not be flashy enough or something.....

Yes, when running it to what it's capable of...

A standard 35 Whelen with 250 gr bullets at 2700 fps (newer Speer data, 2000-MR powder) calculates out to 37.2 ft/lbs in an 8.25 lb rifle (the weight of my 35 AI). I can push it a bit faster with my AI based on having worked up, but I don't need or want that recoil...

My 35 AI with the 200 TTSX at 3000 fps (Power Pro Varmint, Speer data for 180 and 220 gr bullets as the reference and worked up from there) give 33.8 ft/lbs recoil. It's the holy grail of an elk load as far as I'm concerned. Flat trajectory, decisive terminal performance from any sane angle (quartering to or from).

300 Win Mag with a 200 gr bullet at 2900 fps in the same weight gun is 33.8 ft/lbs.

Run the standard Whelen with the Barnes 200 TTSX out of a factory load at 2700 fps advertised velocity and it's 25.6 ft/lbs in the same weight gun.

As some of the others have said don’t worry about what the bore looks like. Concern yourself how it shoots. I’ve had good luck using a product called wipe out to clean my barrels. My gunsmith told me about it years ago and its all i use now. Way better than the standard copper solvents I used in the past. If you decide to put a new barrel on your rifle I’ll second the recommendation on using Hart to replace your barrel. My Hart barrel shoots lights out. Good luck!

I found a CVA scout 35whelen for $400 with 180-200gr ttsx it’s lightsaber.
I probably would buy a 280 to replace the 270 if recoil is a problem

Those velocities are out of a 270 WIN?!

Yes, they are and with Hammers. Plus RL26 is crazy pixie dust for the .270Win. Lots of guys are getting same performance on similar builds. The 700LA provides max magazine COAL that with properly throated barrel can make the .270Win roar!

Learn something new everyday here.

OP what have you decided on?

 

[Stinky Coyote]

if you were happy with the .270 performance you can equal it's 600 yard effectiveness burning about a dozen less grains of powder with the 6.5 Creedmoor, which drops recoil off, shootability goes up, barrel life goes up, and if factory ammo is a consideration then it makes even more sense as nothing is going to outsell the Creed in the next 100 years, you get to migrate to a lighter/shorter standard short action, endless rifle options etc.

take the best of the 20th century cartridges, the .270 win, and apply 21st century performance and you get the 6.5 Creedmoor, efficiency went way up in the 21st, especially the last 15 years

that is the direction to go at this stage in the game imo, and I put elk much further up the tough spectrum than moose, moose may take a minute to pump out but they are wimps and generally laydown will inside 80 yards on most hits even non fatal, not hard to finish, elk best be fatal as their laydown is more like half a mile to a mile lol so whatever you shoot best will be best, no heavy kickers

6.5 prc if you we're looking for more zang at 600 but will touch you a little harder than the .270, otherwise the 6.5 CM will do anything your .270 win ever did with significantly less recoil

Stop that nonsense. 1980 was 20 years ago & if you can't understand that, you're too young to be taken seriously.

I "assembled" a 700LA .270 Win last year with Preferred Barrel 27" SS Light Palma, 1:8Tw, 5R, throated with extra 0.290 freebore to allow max use of magazine at 3.63 COAL, Triggertech trigger, plain jane Magpul 700 stock, Holland heavy recoil lug, 700LA action was trued by Penrod Precision.

This will allow you to shoot heavier, higher BC bullets out of the .270 Win and actually add a lot more horsepower to it. I have 3 loads that I use right now, 156gr Hammer Hunter@3200fps, 170EOL@3075fps and 175TGK@ 2925fps. The 156HH is crazy accurate sub 1/2 MOA at 300 and holds pretty good at 500. You also have the 150ABLR, 150AB, 170BT (new but ladder out to 3000fps), 140BD2 which is crazy BC plus more out there to choose from.

RL26 is the magic pixie dust for the .270 and heavies as well. This will cover 300-600 easily and much further if you choose to do so. The heavier and higher BC will surprise you in energy downrange.

Here is a pic of the dummy rounds I sent to Preferred Barrel to set the throat to give you idea on max COAL you can get to with the 700LA. I was also fortunate to kill my biggest buck with it at 240 yards, not along shot but was nice to see how the 156HH performed and it did so wonderfully. Lungs bloody syrup goop.

PM if interested in more info.

Do you know if this can be done on a m70 classic? I've been thinking about doing it to my gun.

Stick with the 270 win or 270wby. You'll hardly notice a performance difference on game between any medium sized cartridge. The 270 class will do anything, if not better than the 308 will do.
