You don't need a bullet to blow cases out. I made a bunch of .458s out of .300 Win Mags by using 10 grains of Unique, topping up the case with Cream of wheat and plugging the neck by shoving it into a bar of soap. Being .300s they were too long and needed to be trimmed. Now that I have a Lott chamber I'll just use them untrimmed.
Did you have to do much modifying to the magazine and bolt stop to get the Lott cartridge to fit and feed?
