Hello all!
Looking for suggestions, I recently acquired a Di45 from Macon Armory, and it's a lovely thing, and it shoots great, 1in 5 shot groups at 50yrds is boringly repeatable with 230gr J bullets and 6.0gr of unique.
But with cast, I am getting heavy leading on the bolt tail and gas rings, both with Hi-Tek, and powder coat, the boolit is the MP 452374 nlg mold that drops at 240gs with my alloy of range scrap.
Sized .452 and crimped to .473 at case mouth just to remove the flair, so as to not swage them down.
I have tried a few different powders Unique, AA#7, and Vectan A1, all do the same thing, the barrel is squeaky clean, with no leading, and cleans up with just one wet patch and a few dry ones.
The bolt startes getting sticky from the lead build up on the tail and around the gas rings after about 100 rounds, and after about 200 it gets so bad as to not be able to close all the way.
Gas tube appears to only have carbon in it on cleaning, no lead.
Any suggestions from those that run gas guns with cast is welcome!
Thanks for ya'lls time.
