Sounds like the same problem that I'm having. Would you share the name of the vendors you got the larger dia cast bullets from?jisco43 wrote:In July of this year I purchased my R92 in 44 Mag with the 20 inch barrel. Blued finish which wad a deep color with well fitting furniture. Kind of finicky feeding the 44 Mag ammo at first but smoothed out nicely after about 60 to 75 reloads. I slugged the barrel due to terrible accuracy using factory ammo. It was jacketed .429 PPU. I ordered some .432 and .433 cast bullets from two different companies. I used both bullet sizes with 4227 and 2400 powders and have had excellent results and pretty much flawless cycling. The only problems at present are failure from time to time with CCI Large Pistol Primers. Shooting reloads using my second box of primers and I have not had any problems yet.
Thank you
