Few questions for the experienced folk out there. Many places offer 'regular' grade and 'match' grade type barrels. Honestly, what is the diference? If both have 1 inch diameter stainless barrels, is it just a marketing term?
Also, have any experienced "match" type shooters ever specified custom groove diameters?? If so, what have they chosen for their specific bullet size??
The barrel i have has a nominal diameter of .300, .314 groove diameter, while firing a .312 inch bullet (7,62x54r). I know a .308 has a groove diameter of .309, but i've seen some barrels for specific rounds having a groove diameter equal to bullet diameter, and sometimes less.
Basically, what should i choose for my rifle? I'd be building a gun based on the mosin nagant receiver/action & i'm looking to stick to 7.62x54r.
