OP here. I looked into different ammo and here's what I came up with:
>.45 ACP 185gr ammo is basically a .40 short and weak so only stick with 230gr
>Remington usually has expansion issues except Golden Saber but that performs just above mediocre
>Federal HST seems to perform better than Hydra Shock
>bonded ammo performs better than non-bonded
>+p in .45 typically makes a difference in 6 inch barrels or longer, sometimes 5 inch. But mine with a 4 inch barrel won't see an increase in performance
Any thoughts on ammo selection? I'm looking at a case of Speer 230gr JHP 1000 rounds for $499 shipped. It seems $0.50 a round for defence ammo is typical and $0.30 a round for FMJ. I plan on reloading lead for practice ammo once I get a good collection of brass piled up.
