Ok let me spell it out for you mate; point is nobody cares - that's why nobody corrected it - terminology has nothing to do with the problem we are actually trying to solve here.

I see straight through you boy; you're a keyboard hunter. Go tinker with your little computers instead of trolling old threads about using incorrect grammar.

Bit of an update; I had access to the 300m line today to test my Marlin 30/30 with the new (extra long) Williams elevation screw. The difference between the 100m zero and 300m turned out to be a whopping 43 moa. So here'e the revised ballistic chart I came up with:

A lot of drop, but once I found zero, she was really throwing them in there! 8/8 shots landed on paper, and the first 5 were within 6-7 inches of each other (with iron sights!). She opened up after the first 5 as I was rushing (and the front sight rattled loose again at some point; I really need to locktite that down again):

And here's the finalized sights:

And a pic of the re-finished forend:

The forend section was sanded back to loosen up the rear barrel band. I then stained it with a Feast Watson Prooftint "Oak" stain (twice), followed by two coats of Feast Watson "Scandinavian Oil". The result as you can see is almost a perfect match. Loosening the rear band was a factor in obtaining that consistent 2moa accuracy.

Obviously a scope would be a lot more accurate, but that's just wrong on a lever-gun right? So who says a 30/30 is a 200yd rifle huh? :thumbsup:
