After suffering from a nagging desire to get one of these for many years now, it finally welled up inside of me enough that I've got a 16" Rossi R92 in .45 Colt on the way.
Since I already cast and reload for .357 Mag one might have thought I'd go that route. Or, since I might want a .44 Mag revolver at some point maybe that would be the way to go. For some visceral and inexplicable reason, though, it had to be .45 Colt, and thus it went.
I've got three moulds for my 1911 .45 ACP pistols, (one SWC and two ~230gr LRN variants) but I'm assuming the LRN won't be suitable for a tube magazine, and the ~215gr LSWC would be suitable mostly for plinking, though the lack of a crimp groove could prove annoying if I have to seat them deep enough to roll-crimp over the bullet shoulder. So I'm leaning towards a WFN type design in the 240-260ish range. Since I'm brand new to this caliber I'm open to suggestions. One caveat is that a dream of mine is to own something like a Ruger Vaquero in .45 Colt as well and be able to share ammo between them. I do recognize that ammo that's shareable between the two is unlikely to be optimized for either, so as long as the bullet itself would be shareable between the two, it's not mandatory that the loads themselves be (ie: a load that can take full advantage of the 16" Rossi barrel might burn incompletely in a 5-6" revolver, and a load that can burn completely in a 5-6" revolver may leave a lot on the table in a 16" carbine).
If any of you have recent vintage Rossi R92s in .45 Colt I'd be very curious what your bores slug out to just beyond the chamber throat. Unfortunately my sizing dies that I use with my .45 ACP bullets are .451", and I'm not optomistic that the Rossi bore will be .450" once it arrives, so in all likelihood not much of my .45 ACP casting stuff is going to cross over and be useful to me with the Rossi.
I haven't participated on this board in quite a few years, but it's time to be back, and this new Rossi R92 is the perfect opportunity to come back here. So, this thread is for me to just say hi again to everyone here, and see if anyone's got any tips on casting bullets for the Rossi 16" R92 that might help point me in the right direction. I'll order a new mould once the gun arrives and I'm able to slug the bore. What mould that will be is yet to be decided.
