I'm just a simple idiot who likes to shoot milk jugs and recover bullets.
Everything I've shot so far (9mm--- 147 grain Gold Dot and Ranger T-series, 124 grain +p Gold Dot, Hornady Critical Defense , .38--Critical Defense, .357 --Critical Duty, .45-- 230 grain Gold Dot) has expanded beautifully, with two exceptions-- PPU .32acp jhp (no shocker, I was hoping it wouldn't) and some 230 grain Starfire .45acp from around 1999 or so.
The following pics show a comparison of unfired rounds of Gold Dot on the right(purchased around the same time) and Starfire on the left and recovered bullets of each . The Gold Dot stopped on jug #4, the Starfire penetrated all 4 jugs and stopped in the kitty litter jug behind them. When I get a new battery for my calipers, I'll post some recovered diameters.
So is Starfire crap? Has it improved? Just curious. Seems like the jacket was too thick on this batch.
