Ok, next week my Pop, Doc52, is visiting Butch and making some final decisions on his .577 NE. The question we now have is this:

Butch makes his guns standard with MonoBloc barrels, but offers Chopper Lump for an additional $4000.00

What should we have on the big .577? Is the MonoBloc OK? Or is the Chopper Lump worth the extra $4000?

Which is stronger?

Pros and Cons?

Any insight is greatly appreciated!
