Being the dumbass I am, I mortared the Blackout with the Bushnell TRS-25 on it. Want to know how many times? At least twenty. Maybe more. I said I was a dumbass. Most of them were at home, with unprimed cases, trying different overall lengths, case brands, etc. You know what? The cheap thing still works. The groups I shot at a reasonable pace are the same as the groups fired before my fit of stupid. Tough little thing.
