I have had a Winchester 1886 in 40-82 for about 3 years now. I have a large supply of ammo for it. I dont qualify myself as a sharpshooter, but I sure can shoot pretty well. Whenever I tried hitting a target with the 1886, I would always seem to miss or have some crazy flyers. So I started doing some research and someone suggested that I slugged my barrel. So I did. It has a .408 -.410 diameter bore. The problem is that all my ammo is .406 diameter. I was wondering if there was anyways to make the bullets expand in the bore upon firing? Im new to reloading and I have been told this is the site to ask for help.
Yesterday I shot quite alot of ammo, and noticed that when I lubed up the rounds with some of Lee's cast bullet lube, it did pretty well on the groupings. I also did a batch with lube, and drilled out the base of the bullet with a common hand drill. that also seemed to help, I kinda made homemade hollow base rounds.
Any help would be super appreciated. Thanks!
