UPDATE:
Had a brief moment to test this weekend. This is ten shots at 50 yards as quickly as I could shoot/reload the Contender ("easy-open" w/24" MGM bbl) without without slamming it shut but certainly not wasting any time. The two loners outside the group are mine - not the gun, not the load. At 25 yards, you almost can't tell what a three-shot group is because it looks like one hole. POI at 25 is a small fraction of an inch lower than at 50 using the same POA.
This was using 7.5 grains of Unique, CCI 200 LRP, some old mixed brass I cleaned and prep'd. This new plain-based got a dose of BLL, sized to .310 in a LEE push through and another dose of BLL. Have not chronographed. Bore looked shiny and only one flake of "dirty ol' Unique" was left in the bore after this string. I shot twenty of these and twenty of another bullet (gc'd in that case) and no lead left in the bore.
Sorry for the crappy photo. What I save on my phone/monthly phone bill goes toward primers and powder.
Oh, I measured .542" center to center on the eight shots clustered in the middle. If I'd maybe not rattled these off like I did, I'd have not put shots two and eight outside the group like that - maybe. Some days I can even mess up a mayonaise sandwich.
