I was in the same boat a couple months ago but was unable to find any colt ammo at all to feed my new gun. I was lucky enough to find reloading components locally and was able to make 600rds using a lee classic loader from midway. If you can find the components this is a great way to get started. Lately I have had luck getting brass and bullets at midway. I should have 500 bullets and 200 colt brass waiting for me when I get home today
. 45 Schofield brass works for light loads as well.
