Home Forums Hunting & Shooting BPCR .45-100 Remington Necked ?

There are some things in the drawing I question.
One is the case mouth diameter, inside and out. .458" inside and the .490" outside.
The prevailing bullets back then for the matches was the PP, granted Rem used a little larger diameter for the .44's than Sharps or some of the others used. Their .44's were closer to a .45.
Also there is .032" left for case wall thickness. A lot of the original cases I have looked at had a wall thickness close to what we use now and even thinner with the copper cases they used.
There are a lot of differences between this chamber and the shorter 44-90 special.

But this chamber re designed a little would make an interesting round. I favor the BN BP chambers.
