.270 WSM to .25 WSM

Well, I am about to give up on my Savage .270 WSM. It just is not shooting worth a god damn. Velocity is there, but accuracy is not. The norm is 2-3 inches at 100 yards. I've tried couple differenet powders,bullets, OAL's, primers. My question is this, is a Savage worth rebarreling? Is the action worth it? I have a good idea and that is to yank the barrel and put a 28" .257" and making a .25 WSM. What are your thoughts on this?

A 25wsm would barely last load developement.
I give it 300rnds before you can no longer catch the lands.

What action do you have?

try a 130 sbt with imr 4350 i shoot 63 grains it is .3 over the new sierra book max so go slow.also a win mag primer it shoots .5 at 117 yards from my cheap winchester super shadow.i did have to free float the barrel.if there is a guy that can do anything to a savage this is his web page http://www.savageshooters.com/sharpshooters/
i got the info from sierra they say this is your man when it comes to savage rifles.will it not even shoot factory stuff.i have never shot a factory load in mine.

Re: .270 WSM to .25 WSM

I was thinking a 25 WSM with a 28" should easily exceed the .257 Weatherby Mag. Be an excellent deer getter out to 800 or so. I was just thinking the premium barrel would shoot circles around this barrrel. I am just having to much trouble trying to get this .270 WSM to shoot. I have started to see a pattern with all these loads though. It will put 2 shots close or even touching, but about 80% of the time, It will throw one out 2-3 inches. I am letting the barrel cool inbetween every shot at least 3-4 minutes. The flyer does not always happen on the 3rd shot, it will sometimes shoot the 2nd away from the 1st, but put the 3rd back where the 1st is. I have tried the magical powders and bullets for this caliber per shortmags.com with little luck in my particular savage. It is the 03 model without the accutrigger, but the trigger has been tuned to 2.5lb. I like the velocity I see with the cartridge but I need the accuracy. I am getting 3400fps with 140's and 3550fps with 130's. I am going to try a whole new load with RL-22 and 150g Nosler B-tips. Just play around with some other combos that aren't being used as much. If I still can't get it to shoot consistent 1" at 100 yards, I'll definately be getting rid of it.

Re: .270 WSM to .25 WSM

That error is huge.
What you probably have is a mechanical problem with the rifle, scope, or scope mount.


1) Loose threaded barrel joint

2) Bad Bedding, poor stock to action fit.

3) Nicked or damaged or poorly cut crown


1) Bad erector tube assembly, failed spring

2) Bound internals, not mounted straight


1) Loose base

2) Loose rings

3) Scope slippage under recoil

Re: .270 WSM to .25 WSM

I'm in total agreement with S1 , that sounds like some sort of mechanical problem , I'd go through the checklist above and see if you don't have something loose or binding , I would check the barrel channel first make sure their is plenty of space around the tube and if their isin't make some.

If you gonna rebarrel and your gonna be overbore anyway I would suggest the 6.5WSM it'll be splitting the differance in the 270 and 257 pluss you get all those great targe quality bullets to play with.
