[QUOTE="X-man, post: 807401, member: 8416"] I'd have to check my log book, but I'm pretty sure it was 94 grains of Retumbo for 3150fps (30 inch tube). Chamber pressure was in the 64Kpsi range. I used the 200gr SMK and Accubond. Backnitride has potential, but until GAP and the top rifle guys sign off on it I will let others play with the stuff. I have a bore scope...you don't want to own one. :) Normally a 300Rum throat is well frosted by 500 rounds or less. The 6.5-284 don't live real long either...I will be interested if you get much more life out of it with the nitride coating. I am also curious as to what accuracy you will get. [/QUOTE]
