[QUOTE="VinceMule, post: 2845037, member: 122164"] 39.5, and 40.5g of H4350, small primer brass, Rem 7 1/2 107g Sierra hammers groups into bug holes, 8T barrels. I found another node at 41.5g of H4350 difficult to kill the primer pockets on the Palma brass. I have 900 rounds on 30 cases. about the same of R#17 for 100 fps more, but fire cracking will occur within 400 rounds. Op, if you did not get H4350 to work, I suspect that you did not shoot the loads hot enough, or used the wrong size neck bushing, but I am only guessing. I made brass from Chinese military 308, PMC, Lake City, and Lapua 308 Palma, all brass shot 1/4" groups, even the Chinese brass. I use a set of form dies from Paul Bike and neck turned. In my 30" barrel, 107g sierra, nodes were at 2950, 3050, 3150 with H4350 and 3250 with the R#17, all with Palma brass and Rem 7 1/2 primers. I was using a RASS tuner/brake and groups were so small I will not even talk about it. The 6 XC has proved to be about as idiot proof as they come when it comes to tuning a load, crappy brass proved that point. [/QUOTE]
