As I do not want to join another forum to get contact info, can you clear it with Dougguy to post his link up here?
To the OP, your post made (yes, you made me) go play with my TALO 'light' Vaquero Birdshead 45ACP the past couple of days. I have had it a few years but not played with it much. The cyl. throats were originally pin gauged at .4525 and bullets of .452-.452+ did, in fact lead the barrel. Now the alloy was our 'garagalloy', but it has worked well in a variety of guns including rifles up to about 1400fps. I HATE scrubbing lead and lost a whole year somewhere (if anyone finds a year wandering around with my name on it, pls send it back to me).
So, I resorted to buying a cheap box of TULA 45ACP steel case, 230gr. ball ammo at Walmart. I have slowly shot it up and just finished off the last five the other day. I figured the old 'shoot a box or two of jacketed' thru a new revolver cant hurt. Surprisingly they print about only a bit high and (not surprisingly, I seem to do this with sgl act rev's) a tad left and very reasonably tight at 15 yd., standing, one handed (as God, Col.Colt and Wm. Ruger intended). The felt recoil is just fine in the BH. (Isnt spec hardball about 230 @ 830fps-ish?).
I have run some 200-230gr. cast (garagalloy) load development bullets thru it now to find a load that shoots 'to the sights' and have NO leading. I would guesstimate my loads at about 700-750fps, similar to the old 44Spl (really my fav); funny how my cast bullet loads all kinda seem to end up about there.....still, I 'develop' instead of just going there by default :
SO, get a 45 if that is what you want, if it doesnt work out, get another one, see which of the two you like better and sell the one you dont like.
Enjoy the 'hunt'
