You got it. USPSA is normally 5 stages including a classifier stage. They are typically high round count, 25-32 each. Steel is about 1/4 of targets overall (that's a guess). There was a stage of 26 or 28 all steel last year.
After USPSA is done on Saturday afternoon, modification of the stages for Multi-gun begins.
There are usually 4 multi-gun matches a year in April, June, August, and October. The matches are typically 5 stages. I don't have enough posts to attach a link to the stage descriptions, but the round counts for the last two matches were: Rifle-75, Pistol-24, Shotgun-37, Slugs-6 and Rifle-60, Pistol-37, Shotgun-42, Slugs-2
