[QUOTE="SansSouci, post: 1233717, member: 84520"] Good Morning, TDog78, I'm going on caffeine deprived memory alone so it might just be that my remembering needs a cup of strong & black: when gun makers figured out the unlimited abilities of .284 caliber bullets prompted by high velocity, they sold their rifles with barrels with 1:10 twists, probably because .308 caliber rifles used that twist. If it was good for .308 caliber bullets, it had to be good for .284 caliber bullets. It had to have been a really, and I'm talkin' seriously sharp dude to have figured out that .284 caliber bullets had higher proportional sectional densities than .308 caliber bullets necessitating tighter twists for 7MM barrels. Remington went with 1:9. Some gun makes (Sako) have gone with 1:9.5. What do you plan to hunt? I own a 24" barreled Sako 7MM Rem Mag with a 9.5 twist. I've had excellent luck with the once gold standard .284 caliber elk bullet: the 160 grain Partition. I've one-shot-killed a huge, and I'm talkin' massively huge, as in bull moose huge Rocky Mountain bull elk with one 160 grain Partition. It was a through-and-through shot that wreaked havoc on his blood pumping mechanism. BTW, my 160 Partitions are expedited out of my rifle's barrel at better than 3100 FPS using H-4831.
