I had good success with the 30 calibers . but due to the evelution thing went to the old 45/70 and its been doing quite well. but to stay ahead of those toughazz deer I had a special encore barrel made in the 50/70 caliber. my theroy is when they become used to the newer calibers we have to start over with the older calibers as they can only be resistent to a couple calibers at a time. I presently am building a 64 caliber muzzle loader rifle that should really confuse the heck out of them.
