Alaskapopo Posted August 11, 2011 Share Posted August 11, 2011 (edited) Right on Pat!!!! The 1X7 was ONLY for the tracer round, as a matter of fact, the SS-109 round was designed for the 1X9 twist! 1X8 does more than enough and a lot of 1X9 barrels do just fine with 77 grain bullets. I have found that most barrels depend on throat lead, more than twist, when it gets this close. KurtM You're right about 1/9. I have only found 1 gun with a 1/9 twist that would not shoot my 77 grain reloads well. It was a Bushmaster M4 clone. All the others have done fine at least at 100 yards where we where shooting them. pat Edited August 12, 2011 by Alaskapopo Link to comment Share on other sites More sharing options...
Hamma Slamma Posted August 11, 2011 Share Posted August 11, 2011 LOL yeah! I started the great twist reate debate. I wouldn;t dare bring this up at m4carbine because if you shoot anything other than 1:7 you're a loser over there. 1:8 is probably more than adequate. I tend to fall into ANALysis paralysis.
