Add my name to the list.400 Nitro is right on!

I have a big Merkel Double(cheaper Double than a Heym) but would go for a Heym 450/400 in a flash with no regrets--

A new Heym 450/400-Good investment and a blast to shoot. If you shoot the Buff properly, no problem, he will be dead as a stone.

Forget the Blaser-search this site for more info if you have further questions--

Happy Shooting and Hunting!!
