I have a 10ML2 large shank rebarreled to a packer 45. I know that is a 1.12" shank and mine is almost a straight taper. I believe the standard Remington threads are a 1.065". Reason I am asking is that I wanted to shoot this gun bullet to bore and I am looking at what would be the recommend max load with 300 grain bullets and H4198 (already have a pile of 300 Accumax). I know that with HIS for the remage with 275s it was 65 grains, and 300s it was suggested 60 grains. This is a 209 ignition and I know from other testing your looking at 2-3 grains more than if you were using HIS to get to the same place. Looking at some of the old TG pressure traces the are ones showing 70 grains H4198 with 209 ignition was still in the low 40-43K pressure range and I'm not going that high. Wondering what anyone else thoughts are.
