The following are loads I have personally found most effective on pigs. All are in recent manufactured Winchester cases.Following are five shot groups.
Federal large pistol 24gr H4227 250gr Hornady XPT 1416fps
CCI 350mag LP 23gr H4227 250gr Hornady XPT 1436fps
Fed LP 23gr H4227 255gr custom mould 1435fps. Mould on the old 45 Colt pattern .454". The bevel base accepts a Hornady 45 gascheck. Lube/sized to .454 . Alloy is Stereo linotype one part to two parts of new ingot lead.
Another load of 10.5gr of Hogden Universal and the 255gr gave 1325fps. All the groups were shot from a standing post rest at 50yds. Next series off the bench to check the ultimate accuracy.The above work well on game . Have yet to shoot any game over 50yds with the above. Mostly closer as it is running game. More on the rifle setup and sights later.

Tried a Lee 300gr .452 pistol mould with CCI350 mag primers and 23gr H4277. Unfinished load development as groups need to improve. THe uniform velocity surprised me. An extremely clean burn with the magnum primers All loads had smooth extraction.

I do not have pressure test data. As this Rossi action is also offered in 454Casull I decided to use data from the Lyman Reloading manual. IMR4227is listed at a Suggested Staring load of 26.2gr in a 7 1/2"universal receiver with a CUP pressure of 23,000. I believe my load is conservative. Suggested reading is a article titled 45 (long) COLT IN LEVERACTION RIFLES http://leverguns.com/articles/paco/45coltlevergun.htm. There are 10 pages with discussion and loads and CUP data.

Thanks for the information. The hottest I've loaded 4227 is 21.5 grains, and I've put it under 250, 300 and 340 gr lead. Got about 1280 average out of the 340 gr., 1200 out of the 250 gr. I'm using a Marbles 1/16" gold bead front and the Skinner barrel mount peep. Shoots paper just fine. Trying to talk myself into hunting it this fall. Three nice scoped rifles sitting there begging to go, lol
