Townsend Whelen who found out that it drastically increased the bullet pull, to the extent of breaking the test machine. It was extremely good at preventing serious metallic fouling. 30-06 ammunition with tinned cupro-nickel jacketed bullets. I think you most likely will, but at the very least you should work up to it from low charges, and check every loaded round very carefully in case you get an oversized bullet or a case which is thick in the neck.īack in the 1920s there was an experimental issue of National Match. It is easy to say that you would be OK with this sort of fit, in a strong action and with a relatively modest powder charge and cast bullet. I may make a chamber casting to see what we have here.

I have been shooting the same 100 cases for about 20 years and have lost only one to the mouth splitting. Simply re-prime, load powder, seat bullet and shoot. 32-20 if you feel you must crimp the bullets in place, but I have found no need to do this with mine, simplifying the reloading process and eliminating the working of the brass cases.
