[QUOTE="Good, post: 565662, member: 18866"] Ok, here's the "humor me" part How much US-869 would it take to propel a 115g class 6mm bullet to around 31-3200fps given an absolute max barrel length of 24"? My goal is to shoot 6mm heavies fast with cool-burning powder for barrel protection. Anyone have insight on the amount of powder needed? Once quantity is assessed, a parent case will be chosen. This may prove as simple as 243ai or as difficult as 7mm fatso necked down further. :) Any thoughts? [/QUOTE]
