I have a 1917 that has 2 groove rifling. I'm never sure what I'm looking at when I check the bore. I've read on the CMPicon site that most of the rifles they are selling now don't have much if any rifling.

I have distinct rifling in the barrel. A bullet also does not go very deep into the muzzle which is one of the tests I've seen a few guys here recommend. The bore does have some pitting but it is not what I would call a dark bore, but by the same token it's not a bright bore either.

What I'm wondering is if the rifling in these 2 groove barrels just is not as deep as what you find in a 4 or 6 groove barrel. The rifling is pretty wide and if it were as deep as other types, it would seem it might bind. So what should I be looking for here. I know the final test is shooting it which I still have not gotten around to doing so that's still the final determination.
