[QUOTE="hubel458, post: 1404239, member: 6474"] That is what happens, the case side don't have strength and elasticity to spring back a little, it gets good speed for hunting load at 45k psi, but for all out, hot long range loads, won't. I'll be posting more on some testing about this. The side thickness relative to case size affects how much work hardening and tensile strength gets put into the case during the cup drawing process. That thickness in bmg size case would get the proper strength due to the scale of the drawing process to make the cups, and rest of case mfg..ED [/QUOTE]
