So for those suggesting the hand primers, how many cases can you prime before it begins to cause cramps or fatigue?
Depends on what I'm priming. Pistol brass, I can prime a bunch. Normally I prime several hundred without getting fatigued at all.
7mm Rem Mag a couple before hand gets tired.
.308 Winchester brass, a couple hundred. .308 win Lapua brass, about 100. Lapua brass seems to have tighter primer pockets than others.
