Reeder Custom Guns - Who's gunna figure this one out?

I've had this mould for ages, don't know for sure when or where I got it.

Today I decided to cast a few of them. I did not want or need many, just a few to play with. Cast about 80 of them.

This is where it starts getting a bit interesting. The bullet drops from the mould at 260 grains with my alloy. Sized, checked and lubed is about 270 grains. The front drive band is about .450-.451, I think pretty common for Ray Thompson's designs to have an under sized front drive band. I think his theory was easier alignment going into the barrel. The main drive bands are just barely .452.

These will be shot in the 455 GNR and compared to Elmer's 454424 and some LBT LFN's.

is considerably under .450". I forget what pin gauge fits but it's astonishingly smaller. The bullet being forced into the bore (hopefully straight as you mentioned) upsets pretty readily to be filled to the max. I bet it shoots good as long as your throats are not mashing it too small before it gets there.

The proof is in the shooting, not looks or thousandths. They look great.

have all been honed to a perfect tight push through with a .452 sized cast bullet. Cast is the only thing this gun has ever seen.

The Lyman 429490 is actually a 490 gr paper patch bullet.

Years ago I asked Glen Fryxell if it was anything special, he just chuckled and said no. Just a mis labeled mould.

I thought it would be you John, or Jim that picked that up.

You know the narrow part of the bore

The throats on my 455

MOLD NUMBER "429" SHOULD BE A .44!?!?!?

Yep, should be 429.
