PMA Tool Now Offers High-Quality Carbide Expander Mandrels.

Responding to customer requests, PMA Tool is now offering carbide expander mandrels in popular calibers. These carbide mandrels are listed as .22, .24, .26, .28, and .30 calibers, but they are sized for popular chamberings in .223, .243 (6mm), .264 (6.5mm), .284 (7mm), and .308 (7.62mm). PMA’s new carbide expander mandrels will cost $56.95 per item.

PMA’s tool-makers tell us: “Over the past several months we have received many requests to make expanding mandrels from carbide. Due to this popular demand we are now offering expanding mandrels from carbide. Carbide reduces galling and scratching both on the inside of the case neck and the mandrel itself. We still recommend the use of lubricant when expanding case necks to make the operation easier. These mandrels are ground from a 3/8” solid carbide blank and sized properly to expand case necks, preparing them for neck-turning. They can also be used to iron out dings and flat spots on new brass not destined to be neck turned, preparing them for loading and bullet seating.”

PMA Dual Taper Non-Carbide Expanders are Just $8.95
PMA also makes regular steel expander mandrels at a much lower price — $8.95. These regular Expanding Mandrels are designed to fit both the 21st Century Shooting and Sinclair Expander Dies. PMA states: “Our mandrels are longer than other expanding mandrels and feature a special dual taper which expands both on the up and down stroke of the press to more uniformly expand and straighten case necks.” These regular expanders are offered for all popular calibers, from .17 all the way to .338.

PMA Specialized Necking-Up Mandrels for 30 BR and 6 PPC
Last but not least, PMA makes specialized “long-taper” expanders designed to expand 6mmBR brass to 30 BR brass, or expand 220 Russian brass to 6mm (for the 6 PPC). Priced at $9.95, these handy, effective tools make it easy to neck-up your brass for 30BR or 6 PPC.

PMA explains: “So you want to make 30BR brass quick? Here’s the mandrel for you. A while back, while forming some 30BR brass for a customer’s rifle we noticed that after necking 6mm up to 30cal the neck fit on the turning mandrel was a lot tighter than we wanted. Regardless of how many steps we took to get there we had to run the case necks over the final expander repeatedly to get the fit right. After that experience we decided to set out and make a mandrel with optimum taper and diameter to neck 6mm up to 30 caliber in one step. We think is the best way to expand the necks of 6BR Lapua brass [for the 30 BR]. Remember to always use plenty of lubricant when necking.”
