Just looking to tidy up some .20 TAC Dakota brass and turn the necks to get them even. i have found some cases are nearly perfect in the necks and others are varying thickness by about 0.002". Now the narrowest measurement i have found is 0.012" thick so im planning to just trim down to 12 thou for all cases (minimum thickness is 12 thou max 14).
Now i guess these are not massive thickness variations but as i have a good barrel, done by an excellent smith, i think its only sensible for me to try all i can to get things spot on. Plus im on call so i cant have much other fun!
Basically, is a neck thickness of 12 thou going to be ok? i cant see why not but i just thought i would ask some more experienced people.
Many thanks and Happy New Year to Everyone!
