What calilber for my SA build?

[Bamapse]

I currently have a model 12FV in .223 and I am looking to re-barrel it. I am wanting it to be a great varmint caliber for coyotes and the like out to 600 or so but would like to use it for whitetails if I want to as well. Not wanting to get too wild on wildcats because this will be my first build with a barrel change but I am really looking into just a McGowen 22-250. Thanks for the advice! Here are some pictures of the gun how it sits now.

.243 if you don't mind reduced barrel life. .243 is accurate to 1100 yards and you can hunt deer with it if you need to. 3350 fps with an 80 grain bullet.

Read-up on .260 or even .260AI. If I had to choose just one for a do-all, I think that would be it.

Already have a .243 but will look into the .260. Thanks guys

I've heard good things about the .260 and plan to build one this spring.

260 is the next logical choice especially if you reload. You can use your 243 brass.

Double post.

If you hand load look into the 6mm br. 31.5 grains of Varget and an 87 Hornady VMax and your ready to go to 1000 yards.

I like the 260 Remington! ;-)

As a guy that owns two 260s:

Skip the 260 and go 6.5 Creedmoor. It does the same thing a 260 does, but IMO is a 'better mousetrap'.

You would also probably be surprised just how effective a 223 can be on a whitetail, given the proper bullet.

why not just have it rechambered to 22x250 ai? or even a 22x6mm or 243?
its probably a 9 twist which would work with the heavier 22 bullets.

Do you reload? If you don't then you'd probably be wasting time on a .260, 6.5 Creedmoor, or .22-250 for any kind of longer range work. .260 and 6.5 CM just aren't cartridges you'll find everyday unless your shopping online, and the .22-250 just doesn't use bullets heavier than 55 grains which aren't the best for longer range shooting. So if you don't reload I'd really look at the .308 or .243 as the best options for ammunition availability, but only because you don't want the .223. Although my daughter (10 years old) had been using the .223 and 55 grain TSX to hammer whitetail for the last two seasons.

I'm a die hard 6mm fan, I currently run a 6X47 aka 6mm-222RM for varmints, deer, and pronghorn, and a .243 Win for long range target shooting. My next one will probably be a 6XC when my .243 barrel craps out. My little 6X47 will push 70 grain Nolser BT's at 3100 fps out of a 20" barrel and only uses 26.5 grains of powder, which makes it a very efficient little killer of deer sized game and smaller. My .243 is a 1:7 twist that will run pretty exclusively all bullets 105 grains and heavier.

7mm-08

I really love my 22-250! There are quite a few great choices mentioned above though.

[snowgetter1]

260 it will do it all or 243

b.s. i rechambered my savage 223 with a 9 twist to a 22x250ai.
no problem with 69 gr bullets at all. never tried heavier but they might work also.

22br.....run 75's to 90's

What part of my statement was BS? I simply stated that if the OP doesn't reload, then the .22-250 is a waste of time. There is very little factory ammunition out there for the .22-250 heavier than 55 grains, and what there is runs a flat based semi-spitzer bullet that doesn't have any better BC than a 55 grain bullet.

Sure the 55 grain .22-250 will reach 600 yards, but there are better long range ammunition options for the .223 if you have the right twist. I'd stick to the .223 before going with a .22-250 and being stuck with factory ammunition. If the OP does reload then everything I said was moot.

Another vote for the 260. Great do it all caliber.

well if you take the time to read the op and look at the pictures you might see why i said that.
at least to my old eyes that looks like a loading press attached to a very nice loading bench
and he did mention 22x250?
