Anyone out there have a set of reamers for a 7.62x39MM that they are willing to rent?

i don't use a rougher reamer ... i pre-drill to remove excess metal, then bore about 3/4 of the case length deep ... straight bore or if you like math a tapered bore ... this guides the finishing reamer into center with the spindle center ..... and thus the bore if it has been dialed in very closely .

so i don't need to buy a rougher reamer .   but if i did have the rougher, i would use it after boring to remove a little more metal .

with pre-drill and bore, a tool steel finishing reamer should last a few dozen chamberings without re-sharpening .  without pressure coolant flush, typically i feed in 0.050 then clean and re-oil chamber and reamer .. never let chips fill more than halfway up the reamer flutes .

just some thoughts .

If you go to the Gray Beard Outdoors forum, when you get to their opening page on the left is a company that rents reamers, go and no go gauges.  Brodie
