I recently, and unexpectedly, acquired a Cimarron Open Top 45 Colt revolver. It's in great shape and I'm eager to shoot it. Factory ammunition is scarce and expensive; but I discovered a die set from long ago on the shelf, and I have some used cases on the way.
I know that 45 ACP bullets will work and I have a supply of them. It would seem appropriate to load some 255 gr. RNFP bullets for this piece and this raised the question of proper diameter. Do any of you guys have know if the bore diameter is .454 (like older Colts, Rugers, etc.) or .452?
If any of you have a few of your stash to share, I'll happily compensate you and pay the shipping.
Thanks
