[QUOTE="Fiftydriver, post: 687001, member: 10"] I build custom XPs in all chamberings from 223 on up. I think you will find that the 6mm-284 will be a poor performer in the short barreled handguns because of its relatively low expansion ratio. There are some rules to follow to get good performance out of handgun length barrels. 1. The fastest load in a rifle will be the fastest load in a handgun. THere is no need to go to special powders. 2. The lower the expansion ratio, the more barrel length dependant the round will be concerning muzzle velocity. 3. If you take the same capacity and compare it with two differnet bore sizes, the larger bore size will produce higher velocity and often times dramatically more velocity as the barrel length decreases. For example, if you take a 6-284, 6.5-284 and standard 284 Win. The 6.5mm-284 will drive a 100 gr bullet probably at least 100 fps faster then the 6mm-284 will drive a 100 gr bullet weight. The 284 Win will likely drive a 140 gr bullet nearly at the same velocity as a 6.5-284 will drive a 120 grain. If you want as much velocity as you can get out of a shorter handgun length barrel, step up to a larger bore size. I am a fan of the TC handguns and rifles for that matter but they are not nearly strong enough for the big, high performance chamberings. Even moderately powerful chamberings have to be loaded pretty conservatively or you will start to get serious case stretching in the TC. Compare that to a bank vault strong XP-100, there is no comparision. [/QUOTE]
