Re: Semi auto vs bolt dies
SB dies size the case full length, but they size it to a smaller dimension. Depends on the manuf, but typically by .002-.003"
I would suggest that you try the FL dies first, no need for SB dies if you don't need them. There isn't any advantage to using a SB die if the gun does just fine with FL sizing. The only slight disadvantage to SB dies is the fact that they work the brass just a little bit more. As to whether or not this affects case life in the real world, I don't have definitive proof, but simple logic implies that the more you work it, the shorter the life. Alot would depend on what loads you're going to use, ie How Hot?
