I just bought a Ruger Bisley 45LC/45ACP covertable. I have 200 gr. Missouri Bullets .452.dia. to use in my 45ACP cylinder. I have Lee 4 die set with the FCD. Will the taper crimp work ok? Or should I roll crimp? I am not loading for hot loads ,just plinkers. Any comments welcome.

Taper should serve you well at normal AP power.

+1 I used that very bullet with a light taper crimp worked good.

You need to taper crimp just like for your 1911 as the round still seats on the case mouth.

I acquired a new Ruger SS Bisley .45 Colt/.45 ACP Convertible last year. The revolver is extremely well made and finished. However, the throats were undersize (about .450") on both cylinders. Two friends who also bought at the same time discovered the same with their revolvers. Mine shot well in .45 Colt using home cast 454424 (NOE) bullets but started leading after about 30 shots leading to wild shooting. I could not even chamber my regular .45 ACP cartridges loaded with Mihec 200 gr SWC (H&G #68).

I borrowed a Manson "made for the job" reamer kit with pilots and reamed all six cylinders to .4525". After this, my revolver shot like an NRA Bullseye pistol. Groups well under 1" at 25 yards are common. My friends reported similar performance.

My .45 ACP standard target load is the previously mentioned #68 H&G bullet ahead of 4.0 grs of Bullseye (or equivalent) taper crimped to .470" at the mouth of the loaded case.

This is one of the most useful field revolvers I have.

Thanks for all the info. I figured I would probably have to ream the cylinders. My gunsmith did my last revolver for around $50. so 2 cylinders might be a bit more. Have some 250 gr Missouri bullets loaded with 4.8 gr Trailboss for starters. Guess I will go from there. Thanks again.
