isnt there something about shooting more grain and less grain....like on a 1/7 more grain is bad.

i thought i read that somewhere?!?!

The heavier the bullet, the faster you want the twist. So a 77gr is good on a 1/7/ a 77gr is not good on a 1/9

Also, the 1/7will shoot the lighter weights just fine, so a 1/7 will also be great for 55gr. Thats why a lot of people like the 1/7

55gr-62gr will do you fine with the 1/9

From the Ammo Oracle:


Q. What twist rate do I want for my rifle?

Probably 1:9, but it depends on what kind of bullets you intend to shoot.

Special purpose rifles often have uncommon twist rates.  For example, if you are building a varmint rifle and want to shoot the short 35 grain, 40 grain, and 50 grain bullets, a 1:12, or even 1:14 twist would be best.  On the other hand, long range High Power shooters often select 1:8, 1:7.7, 1:7, or 1:6.5-twist barrels to stabilize the long 77, 80 and even 90 grain bullets used for 1,000 yard competition.  Additionally, new testing of heavier rounds (68-77 grains) seems to show that they perform very well in simulated tissue and may be a better defensive choice than 55 grain or 62 grain rounds. The majority of shooters, though, typically shoot bullets of 50 to 69 grains in weight (note that the 62gr SS-109/M855 bullet is as long as a 71 grain lead core bullet) and should select 1:9 twist barrels.  At typical .223 velocities, a 1:9 twist will stabilize bullet lengths equivalent to lead-core bullets of 40 to 73 grains in weight.
