I'm looking at buying either the Remington 700 SPS Tactical or the 700 SPS Tactical AAC-SD in .308 soon, the only thing holding me back is the difference in rifling between the 2 barrels. I really want the AAC-SD version for the silencer cabability or muzzle brake, etc. as it comes with a threaded muzzle out of the box and I simply like the color of the stock better. However, the AAC-SD comes with a 1:10 rifling twist to help stabilize heavier bullets, 168 to 220 grain. The regular SPS Tactical comes with a 1:12 twist made for 150 grain bullets. I plan on hunting and paper punching with it but 90% of what I shoot out of it will be 150 grain bulk ammo for fun and target shooting simply because I have a lot of it and it's affordable. Will the 1:10 barrel twist have an effect on accuracy at distance or make the bullet unstable because it's lighter? I've read a few threads that say the faster the rifling the better but just curious if anyone has experience with 150 grains out of 1:10 barrels. Thank you for your help ahead of time!
