I've known about this ctg. for some time but never gave it much though because I wasn't into 1911's for quite a few years BUT now that I'm back into em' I'm taking notice of this ctg. and it really looks like a winner. Basically just a barrel fitting to your current 45acp 1911 and you're in business. Ammo can be made from 45acp brass sized and trimmed and Lee even makes dies for it, $28 bucks, so you don't need expensive dies(like the RCBS 7.62 Nagant Revolver dies, $160 bucks last time I checked, OUCH!) so I just wonder why folks looking for 10mm Auto performance out of their 1911 who already owns one in 45acp just wouldn't do a conversion. Was there something "wrong" with this cartridge that I've not read about or is it just Old News in the 1911 World. I mean I know it's been out for some time but still, 155gr JHP at 1300fps is nothing to sneeze at with a barrel change in a 1911. Once I get a few other things done to my gun I'd really love to get into this ctg. so I've got something to play around with. I've always loved messing around with "odd ball" cartridges. So who's got em', what do you think about it and does it really live up to the ballistics that I've seen on the reloading forums.
