[QUOTE="just_jon, post: 2458624, member: 112153"] I just ran your data in QL and believe IMR 4955 is too slow burning for this bullet. My normal practice is to find a max pressure load in QL and reduce by 10% as a starting load. In this case, QL estimates 64,958 psi at 35.8 grains. That would put the starting load around 32 grains. The problem with 4955 in this situation is 32 grains nearly fills the case (98%). I would recommend something along the line of IMR 4064/4166/H380/Varget as each is projected to reach max pressure with a load density around 95% fill rate. [/QUOTE]
