"Cowboy" low-power 454 Casull/ 45 "Extra Long" Colt loads for R92?

I'm sure I'll end up with a short-stroked 38 or 45 toggle link gun at some point; if anybody ever sees a great deal on one let me know.

In the meantime I'd still like to make the R92 run as well as possible. I have a few new things to try now thanks to ya'll's help. I'll report back on my findings.

Very interesting.  My R92 .454/.45 will feed any RN/RNHP/RNFP and LeveRevolution ammo with no problem.  It will not feed WC/SWC in either cartridge.  I reload the .45 but don't fire enough .454 to make it worthwhile.  In a typical year I fire one .454 for zero confirmation and one round to take a deer.

I also probably need to get more into the guts of the rifle.

I've seen a few conversations with folks talking about shimming things, and I haven't played around with that yet:

I bought the DVD from StevesGunz, but I didn't see how any of the modifications Nate discusses would improve feeding. According to Nate, "some guns just are sensitive to some ammo"... I'd rather this gun be allergic to Casull than 45 Colt. Like you, I'll probably only ever be shooting one Casull at a time.

And the biggest Casull rounds don't even fit into the loading gate... The only 454's any of my local gun stores had were DoubleTap's 400 grainers; 400 grains at 1675 fps, about as much muzzle energy as a 308, but they turn the gun into a breech loader!

for .454 I use 260 gr. Winchester Platinum Tip.  They feed with no problem.  They are RNHP.
