I would like to include Siace as I have a very beautiful and functional double rifle from them that I bought last month. It is 45-70 as that is the caliber that I wanted. If you question the ability of the caliber, then look at garrett cartidges .com. So much more refined than a Merkel which I owned, but then aesthetics are a big deal to me. Look at their websie, www.siace.com.
