Which big lube for 45 colt conversion?

[Cliff Fendley]

I'm trying to decide which big lube bullet to run in a Kirst conversion in a Pietta Remington. Because of a bad disk in my neck I would prefer to try a lighter bullet than the PRS 250.

I'm thinking the lighter bullet would keep recoil down but not sure since it may take more powder.

Also should they be sized at 452 or 454? In the percussion cylinder I generally shoot 454 round balls but 451 shoot accurate too.

I've been shooting the MAV big lube in 44 with great success so I was looking for advice on which big lube for this 45.

I have the EPP-UGG, same weight as the RB, and I just got the .45 SLIM at 170 gr.  Why don't you get samples of each and try them out.  Either one would work in the Schofield or the Special case.

The J/P 45-200 was developed specifically as a lighter 200 grain alternative to the 250 grain 45 PRS bullet for shooting in my Remingtons with R&D conversion cylinders. Because of their grip configuration, a 250 grain bullet fired out of these guns creates uncomfortable recoil, at least it does for me. Yes, the J/P 45-20 does create more space in the 45 Colt case, allowing for more powder, but the lighter weight compensates for the slightly larger powder capacity. The lighter 200 grain bullet helps make them more comfortable to shoot. It will do just as well in the Kirst cylinders.

It works even better loaded in 45 Schofield cases with about 28 grains of so of FFg. I did have to have my R&D cylinders modified slightly to accept the larger rim of the 45 Schofield case, current versions of that cylinder will accept the larger Schofield rim. I cannot say whether the Kirst version accepts Schofield rims or not.

The J in J/P 45-200 stands for Johnson. I size all my 45 caliber bullets to .452. When you seat a .454 round ball you are shaving off some lead. There is no shaving of lead required with a cartridge bullet.

45 Slim in Cowboy 45Special brass is a great combination. With 3.5g Trail Boss it's accurate as all get out and very clean.

Thanks for the info fellas. I was considering the JP 45/200. I might call  Kirst to see if Jay knows whether the Scholfield cases will work.

DJ, I knew you were involved with the development of that bullet but didn't know if was actually for a Remington conversion.
