[QUOTE="brianwinzor, post: 65142, member: 1067"] Jeff, Many thanks for a very informative post, and it certainly appears that you trail blazed on the JLK 90 in the AR 15. Regarding the length of the JLK 90. Am I correct in that the 1.227 - 1.325 is a "typo", and should probably read 1.227 - 1.235? This prompts my next question. How did you and most other shooters seat these bullets for best accuracy. Out, touching, or at least .005 or more into the lands? You mentioned that the 4 groove Krieger 6.5 twist gave less velocity than the Pac-Nor 3 groove with the same twist. Was the accuracy similar with both barrel configurations? Also, did anyone notice that barrel life was better or worse with the 4 groove than the 3 groove. Regards, Brian. [/QUOTE]
