Hello to all. Hope everyone's doin OK. It's been quite a while since I asked a question on this forum. Anyway, I have an ASM mfg'd EMF Hartford SAA replica, which has .454" grooves in the barrel, & .454" throats in the chambers. I was wondering if anyone knows of a commercial caster who might offer a bullet, whether roundnose or SWC, in the original diameter, to see if they would improve the accuracy any, as I've read that .45 Colt guns with tight barrels shoot better with .454" bullets, which has proven out on my .45 Colt rifles & a USFA SAA I have. Thanx for your feedback, JD45
P.S. I recently bought some Remington .45 Colt bullets from Midway, advertized to be .455", but after miking several, I found them to be only .453".
P.P.S.....I don't have the inclination to cast my own, thanx.
