Changing caliber

I have a Stevens .25-06 that I bought and was thinking about putting a shilen barrel on it. What calibers choices do I have with my stock action? Maybe a newbie question.

Re: Changing caliber

Hi there smallbutfierce. When I found myself in your position I had to re-barrel because I didn't want another caliber to load for. I asked myself: Billy, what are we going to shot with this gun? Then I picked a caliber that I had to outfit myself for anyway! Ended up with a .338 Federal. Your Stevens would make a great platform for the .338-06, .35 Whelen, or any of the long action '06 size bolt face calibers. Lots of potential. Sounds like a lot of fun times ahead for you. Keep your powder dry.

Re: Changing caliber

Thanks guys. That first reply was just what I was looking for. And Chugiabilly, this game is a tough one, too many calibers, too little money. haha. I bought this gun for its ability to shoot 85gr and 120 gr bullets, covering the game animals here in Maine. The big decision now is do I keep it for hunting, or switch it to a target rifle. I have a lot of research ahead of me. Thanks, again.

Re: Changing caliber

Or you could go 25-06 Ai. Fire form the brass you have. Presumming you reload and and saved your brass. You'd be knocking on 257wby's door and and have all basic components minus the dies. If ya like the performance of the 25-06 you'll love the AI version with out having to change bolt head. Not that it's hard just extra expense. Great post up in Reviews about the 25-06 and the 25-06AI. The .25-06 and .25-06 Improved By J.C. Munnell

Re: Changing caliber

I have always been interested in the AI. On paper it looks like a screamer. I can't reload yet due to space constraints in my tiny apartment, but when I finish school I will be all over that caliber. What would be a good barrel spec? 26" with a 1-9 twist to shoot the 115 vlds or Nosler ballistic tips? I also like the looks of the 6.5-284, but I like the look of a lot of things. haha. Too many choices.

Re: Changing caliber

I would take a hard look at the 280AI. Just a barrel swap and your shooting. 7MM bullet have a great BC. Factory 280AI ammo is now available for you to shoot and collect your brass for when you do start reloading. Standard 280 Rem ammo shoots great and also leaves you with a great fireformed case for later. You can load 120grn pills that will beat the performance of the 25-06. Hot AI loads nip at the 7mm Mag's heels out of an '06 based case. You can load it heavy with 160grn or 175grn and have a load capable for just about anything. I have no problem making 500-700 yard shots on antelope with 140 accubonds. So far ALL DRT. Just my opinion. I like the versatility of this cartridge from long range coyotes and deer to serious elk or moose thumping.
