The 33 1 6/10 WP is a 357 Maxim necked to .33 caliber, barrel by Ron Smith, Breech seated 1/16" ahead of the case, Federal 100 pistol primers and my own lube, 11grians of AA No.9 no wad. Bullet mix is 20-1 lead-tin, all the same weight, pan lubed.

At 100 yards I tried my old Alox-Beeswax lube,

0.665 for 5
0.480 5
0.390 5
0.675 5
0.670 8 of my foulers
