300 blackout: crimping yes or no?

[Dirtchevy841]

Just seeing if crimping is a yes or no or both. Have done both but really haven't noticed to much difference. If u use a bullet with no crimp grove should it be crimp. And is it even worth the extra time to crimp 300 blk.

I don't crimp any of mine, smk or cast. But I dont crimp any of loads.

I place a very light crimp on all of my 300BLk loads.

Light crimp

I don't crimp my 223 loads and don't think it matters whether they are crimped or not. So sometimes I apply a light crimp with a Lee factory crimp die and sometimes I don't......

Yeah that's the same thing I do. Just wanted to get opinions. To me it saves a lot of time when not crimping on single stage. Now on my 650 a light crimp is no big deal but that's only used when I do volume reloading of 223 or 300. I still really like the single stage though.

I put a light crimp (Lee FCD) on my supersonic loads and do not crimp my subs. Not enough recoil to matter much either way I suspect.
