Gunsmithing rate of twist questions for .223

[spswatip]

Ok, here goes. I am not up on twist and bullet weights and stabilization so here is my question: I have been looking for a rem 700 .223 and have wanted a SPS tactical w/ the 20" barrel. These are 1 in 9 if I'm not mistaken. I have found a SPS varmint w/ a 26" barrel but it is 1 in 12 twist. The ammo I get is 55 grain FMJ american eagle, but I could start reloading again if needed. My question is if I bought the SPS varmint what length could I cut down the barrel to and still get decent performance. I realize I will loose velocity as I cut the barrel down but my concern is more with stabilization than velocity, and I want a shorter barrel rifle.

I have a factory Remington VLS 22-250 in 1-12 I believe and it has been turned into a AR-15 varmint gun. I think I finished it off at 20".

Anyway, it shoots awesome. I think if you have a decent barrel you will still be fine for what I think you are using it for.

1:12 will be fine as long as you stay 55gr and under. Shortening it won't hurt the spin.

And not likely but if I do decide to shoot heavier bullets would the shorter barrel w/ the 1 in 12 twist create a problem?

yup. 55gr is about it for 1:12. 1:9 will do 69's for sure and some 1:9's will do 75/77 non-VLD's.
