Let's see, new gun, new Lee Shaver mid range soule sight, new Lee Shaver globe front sight with level, new brass, new bullet design, new load workup.
I finally got a few spare minutes to get 'er on paper. Took me Nine shots to get a nice tight group at 100 yards. Next week or so, she flys to 300 yards.
The new bullet, when seated and crimped on the crimp grove, chambers right up to the rifling. If I chamber a cartridge and extract it, I can just barely see the beginning of the rifling engraving the bullet. So, no jump to the rifling here.
I'll reload those Nine pieces of brass without resizing them and only crimp enough to keep the bullet in place. The chamber on that Winchester is right on the money. The sizing die isn't really needed at all.
A compressed load of FFFg Swiss with a Circle Fly fiber wad under the bullet seems to be all that is needed. The new Big Lube™ twin grove 38-55 bullet hauls plenty of lube. I had a nice lube star on the muzzle when I finished shooting and a single spray of Moosemilk and a pull of the Boresnake did all my cleaning chores in less than Two minutes. Life is good.
Soon as I can shoot some long range paper and graph the rounds, I'll report back.
