I am new to re-loading and have so far only loaded black powder in .45 Colt, I am about to load some Unique smokeless and was wondering if the air space in the cartridge is going to be a problem. With black powder light loads I was using wads to fill the extra space. I am going to start with 7.5 grains of Unique which only fills about 1/4 of the available space in the cartridge,is it safe to have the air in the cartridge above the powder???
