[QUOTE="DSheetz, post: 2745381, member: 91783"] My 1:9 likes a little heaver bullet then 55 grains and you have 50 grain bullets that you want to shoot. If you go to say Bartlein barrels web site and look at twist rates vers bullet weights, they will give you a suggested rate of twist for different bullet weights. The old M-16 was designed for a 55-grain bullet with a specific powder burn rate and they started with a 1:14 twist rate then went to a 1:12 to stabilize the 55 grain bullets later models then had some that had 1:10. now they want to use a heaver bullet 62 grain and even up to 75 grains thus they are running the 1:7 and 1:8 twist rates. Twist rates are an important part of a build and there is a lot of information out there so a person can match it to their intended bullet weights. [/QUOTE]
