Weekend results...I made 100 rounds of 380 auto and 100 rounds of 357 "Mag" ammo (actually 180 grain gas checked lead boolets in 38 SPC cases) on my RCBS Piggyback II progressive loader with 700-X for plinking. Every round went "BANG", all of them shot to point of aim, some even hit the target!
I was shooting each of Walther PPK 380 ACP; 357 Mag. Ruger SP 101 revolver, and 357 Mag. Handi-rifle (a great gun).
Significant differences between Unique and both of 700-X and Hodgen Clays is the amount of powder (700-X or Clays is small), the load manual (Hodgen) says "...not to exceed..." and I don't so the 38 SPC cased round is nowhere near the intensity or power of a full 357 Mag load - particularly in the Ruger. I would not want to be on the "Business End" though.
I didn't target shoot this weekend, just burned primers and powder launcing projectiles down range having fun plinking. Add those to four 223's, a 280, three AK-47's, a 35-40 Krag, four 9 mm semi-autos, two 40-cal. semi-autos, three 10/22's, a "Noisy Cricket" 25 cal. semi-auto, and six "Scare Crows", means we made a mess! But we had fun and picked up after. Dang it was HOT!
