Jay Andrew, does quick load allow for pistol cartridges and long barrels? i have a silly idea of building a 357 sig carbine, with a 16" barrel and was trying to figure out if it was worth my time or not? if you see this and have the time i would like to use 124gr xtps but just some general information form quick load would be awsome maybe a comparison between 10.5" and 16"? who knows why i think these things! thanks a bunch!
