Never used them but a lot of people like them. Elmer will probably know for sure. I think he's scanning books so he may be awhile. Chris

These may be closer to what you want. Chris

I use Black  River bullets and they are great not to mention reasonably priced

I was actually going to try the Black River bullets next time I need some. I have several hundred old Bull-X that I got years ago and have been using them up. Good to know the Black River bullets are ok. Chris

Thanks for the information. There are a few options available here that appear to be close, although it seems that Black River has discontinued exactly what I'm looking for!
The 255gr. is a good compromise between velocity and  weight. I imagine the powder charge would have to be reduced to keep pressure acceptable when going another 10 grs heavier...Anyone tried the B.R. 265s?

...that don't visit much but are both quite knowledgeable in their own rights are LAH on the sixguns forum (yep, I'm sending you back there!) and Gunsmith active on this forum. Give them a PM and let us know what you find out.

Thanks, Al-sent them out, will see what comes back.

Thanks for thinking I know something. I only repeat what Elmer said, and I have done and found works well. The RCBS mold is a vertual twin of Elmers original (45/255 K). FInd someone that will cast this for you. I am sure some lod timer will do it for a case of beer, or a similat price for you. You really should cast them yourself though. Then you can sixe them to a correct dia. for your gun, and get real acuracy.  I amd casting for the 45 lc now, as I am feeding a Ruger Old Army with a Taylor Cylinder conversion. What a nice gun that one is. Powerful, and accurate. Not a fast loader, but if 6 shts do not solve the problem, I am in a world fo crap, that a reload will not get me out of. . I fight with my revolver so I can get to my rifle. Then the music starts.

Gunsmith,I agree with you that it would be best to cast them myself, however, without getting too personal, or boring people with my details, lets just say that we over here have undergone a personal tragedy that has us living in a very small and crowded space, where casting is impossible.
Which RCBS bullet/mold were you referring to, sir?

Gunsmith 
      I would disagree with the RCBS mold being virtually identical to the original. I made many measurements on Lyman, RCBS,  and Mountain Molds. I compared these to a vintage H&G mold. I was really shocked at how this bullet has morphed over the years. I continued my quest and found Arsenal molds. They stated that this was the original 429421. So, I ordered one and started my measurements over again. The Arsenal mold is the closest that I have found to date.

I only have used an old Lyman mould and the RCBS. That and went by Elmers writings. If I was wrong I appologize. I can tell you I was able to hit a fire extinguisher placed as a target well over 100 yards away with my second shot. It penetrated the tough metal and put on quite a show. This was done in ohio.

LAH was trying to get a hold of you on the Sixguns forum, did you hear from him?

I dont think anybody did but I will check, Thanks

Hmm nobody tried to contact me

...end in 4151? Lynn was trying to get a hold of you about some work on a Smith on the Sixguns forum

Lynn found me. 

When you get done we need some photos.  What are you doing to the revolver, anyway?
PS the 629 Classic is still as tight as ever. Hundreds of full blow magnum loads and several thousand IPSC and plate loads later.

Wish I could do it for a living
