We've done it a lot rifle hunting with both bulls and cows. I had my youngest out last fall trying to fill my dads tag taking advantage of the mentor program here in OR. Had a herd of 8, 6 point bulls run past at 150 yards. My sons 10 and couldn't get a shot with them moving, but a friend of the family's son and nephew were just up the ridge and doubled up on a 320is and 290ish 6x6 and 6x7 bull, those are the biggest I've seen doubled up on. We've killed over a half dozen cows out of the same group over the years on several occasions, part of the reason I took up archery, kind of like shooting fish in a barrel IMO.
My two boys doubled up on deer about 10 seconds apart last fall, 10 & 13 years old, that was super fun for them. I've yet to double up archery hunting but I've shot several bulls and had another bull walk into range and just stand there several times over the years.
Cow season starts here in OR on Aug 1st and we plan on filling 3 or 4 tags open day to put meat in the freezer before archery season starts.
