Tested my first two .45-caliber bullets today, shot from my 38. As I've done and reported upon in the past, I shot them into 1-gallon water jugs, 4 front-to-back and touching, from 10 feet. The factory ammo is the Winchester Super-X 185g. Silvertip hollowpoint, while I've reloaded nothing but Speer Gold Dot 185s. The velocity of the STs disappointed me at 918FPS (at first-screen-at-10-feet), while I've managed to get my reloads using Universal* up to more than 1075FPS, altho I've settled on a load with a velocity of about 1040FPS. The Silvertip performed adequately, expanding nicely and not coming apart, but the GoldDot was again the star performer, expanding fully, staying together, and looking great in the process. As in my 40-caliber tests, a portion of the core of the GDs stays attached to the expanded petals of the jacket, reinforcing them. * Chosen for its lack of muzzle flash; see http://findarticles.com/p/articles/mi_m0BTT/is_190_31/ai_n27380935/ .
