Yeah, stake shoots are the only time we get sort of silly/rowdy. Several stakes are set out and a team is assigned to cut each one. Last year we had something like 20 shooters firing all at once, two sessions with a total of almost 40 shooters. Quite a bit of noise.
Like Bullwinkle says there is a fairly high round count, though we revolver types don't spend too many as the race gun types have their 20+ round mags and don't take the time to reload often.
One of the revolver shooters does shoot a 625 with .45 acp rounds, so maybe that will be the ticket.
Thanks!
