PMA Large Caliber (35-50cal) Model A Neck Turning Tool

The PMA Big Boy Model A Neck Turning Tool is a scaled up version of our standard Model A Neck Turner and is packed with all the same features. Just as the name implies, this tool is sized appropriately to handle neck turning of 35 caliber up to 50cal cartridges. 

The PMA Neck Turning Tool is the best neck turner available today. You know why you need or want to neck turn, but with so many different models on the market, which do you choose? The factors determining your choice of neck turning tools essentially boils down to three key demands; ease and repeatability of adjustment, comfort of use and cut finish. This tool absolutely satisfies these demands.

Our neck turning tool does not use a course or fine drive screw to move the cutter towards or away from the mandrel. We don’t utilize an unnecessary micrometer or dial indicator. Nor do we rotate the mandrel on an eccentric which changes the center of the cut and has inconsistent adjustment. Our Model A simply adjusts by moving the mandrel toward or away from the stationary cutter with VERY minimal backlash. The Model A utilizes a super-fine 80TPI drive screw giving you .0002” adjustment between each mark, the marks have ample space between them allowing you to make adjustments as fine as .0001”.  Tool does not include mandrel.

Our large caliber neck turning mandrels are sized appropriately to work with expander mandrels from Sinclair International.
