I know that 1911's are very picky animals... I know they hate bullets that arent ball... But come on!! Haha.. So far I have tried 6 types, the first were squared off, cant remeber the brands. Then I started looking at the rounded HPs. Winchester Supreme Elite 230 gr Bonded PDX1 JHP And several styles of Federal Hydra shock.. They all just keep getting caught in the feed ramp. I have heard horror stories of guys trying to file them down their selves another mishaps. Does mine need to be filed down or just Polished? I have a Taurus PT1911... Its had 300 rounds of ball through it with no malfunctions. Thanks folks.
