Here is what I run. It has interchangeable barrels and I run a 7mm stw, 375 h+h, 257 weatherby mag on it.The cope stays on each barrel and with 2 screws the barrel pops on and off and the zero stays the same. I am using it for my Leopard, Buffalo and plainsgame hunt in Africa next year and can hunt it all with the same gun and just switch barrels. The bolt is a push - pull system as well and is way faster than the other bolt guns out there. Light weight and shoots half inch groups. I put Kahels and swaros on for scopes http://www.blaser-usa.com/R-93-Characteristics.119.0.html?&L=peotegxpiwlmvf
Dick, what are your thoughts on the "gain twist"? I understand that Ron Smith is a spectacular builder of barrels, but what are the specific advantages of the gain twist? I understand there is an increase in velocity and possibly less fouling but do they offer additional bullet stabilization (accuracy) over a standard twist? Regards, Mike

Regards, MikeI spoke to Ron about this exact thing yesterday. He said, you should get slightly more velocity and barrel life, and they shoot every bit aswell/ sometimes better then standard rifling. He also mentioned most guys that try them, order their future barrels with the gain twist.
Maybe I don't undrstand gain twist. But it would seem that constantly enlarging the engraving on the bullet as it travels down the barrel couldn't help the barrel do any increases in speed, accuracy or barrel life?
Here is another by Leeper that recently stopped in for a visit:I will let the owner tell the details...
