Gets cases trimmed, leaves a lot of room for quality - Lyman 50 BMG Accutrimmer 7862130

I have used this trimmer to trim 500 rounds so far. IF i had done so manually I think my arm would have fallen off. Military brass out of spec .001-.100 and more... that's a lot of trimming on some. The shaft is too large in diameter to fit in a 1/2" drill chuck, and too short. I took the shaft out and had a friend of mine turn one out of a HARDENED steel, 1" longer and rebated to .450 on the extension part. TA-DA... attach 1/2" power drill and go to town. Loc-tite the trim pilot and (bottom side) cap screws in place and keep the shaft lubed. Works great.
