300 ultra,
Check out this website- levergunleather.com.
Lever is based out of Athol, ID and I highly recommend him. I had a butt stock cover made in black leather with a 4 pt. mule deer buck and my first name on it.
He added on 3 bullet loops also.
Every one of his pieces is a one of a kind hand tooled piece, not stamped out.
Lever is a true craftsman and you will LOVE his work! The website has many pictures of his work. Lever is great to work with.
Enjoy the process!
Randy
