Lyman™ Lube and Sizer Die 251 Diameter

The Lyman™ Lube and Sizer Die 251 Diameter now have 90 degree hole spacing. It is now easy to lubricate bullets even with today's hard lubricants. Lyman sizing dies also feature a tapered mouth and hardened interior insuring alignment for perfect cylindrical shape. Interior dimensions correspond to suggested diameters for all popular rifle and handgun calibers. Fits Lyman 450/4500 Lube Sizer and RCBS Lube-A-Matic-2 Bullet Sizer/Lubricator. Sizer dies also help to crimp the gas check on the base of gas check style bullets. 

  1. This lube/size die works ... review by Michael on 6/14/2017

    This lube/size die works as it should. Cast bullets enter easily, line up true, get their lube at the bottom of the stroke and come out sized perfectly round with square gas checks on the bases. I use mine to size the Lyman 65 grain flat nose .257\" caliber bullet(meant for a .25-20) down to .251\" to shoot in a .297/.250 rook rifle with a .251\" groove diameter. The actual diameter after sizing (as best I can measure it with a micrometer) is .2515 \"using wheel weight alloy. I tried some bullets of linotype , and they came out right on at .251\", go figure? I use Alox lube and a RCBS lube/sizer. The Lyman and RCBS lube dies are interchangeable. Some day I might even use it to size cast bullets for my FN Vest Pocket .25 ACP!

  2. 0.251 review by William Stewart, ETC USN Retired. on 6/14/2017

    I purchased this die to resize .257\" nominal bullets to .251\" nominal size for use in a .25 Stevens RF rifle converted to CF. So far it is doing what I needed it for quite well.

    Now I will be looking for one size to .253\" nominal diameter for cast bullets for another barrel that slugs .252 groove diameter.
