Were I to build a ShamWow Niche Rifle,it'd be a dupe of my LFB,though wearing a #2 contour instead of a #3. It'd never begin to touch a Montucky for Utility,but it'd be a fun Play Toy.
I'd want a throat that kisses the 162 at 2.850" and would feed it DBM(Atlas) ala S/A 700 and 5rd AICS. The 162 at 2950fps,is a nice place to be and far from offensive to the shooter,sans brake.
I hear good things about 7mm's.(grin)
