I've been having fun with my 6x45 for the last year. Very easy to convert 223 rem brass to 6x45. Just run it through the die and you are done. Simple to load for, but you are limited to the type of bullets it likes. That's the main downside to the cartridge. But, with that being said, mine likes 100gr hornady btsp's for heavies, down to 58gr pills. It really likes the 85gr Sierra gameking for a do it all bullet.
I agree about the 85 gr Sierrasin my 6x45 I bought a bunch of 85 gr partitions thinking they would be the cats ass but can't get them to shoot worth a [bleep].
