Yes. Normally the groups are of similar size. Especially now since the AR’s have been in place and we actually have older bucks common enough to form a group.
On a couple rare occasions I’ve seen a big buck with a smaller one, but that isn’t typical.

The greatest bachelor group I ever saw was a few years back that I called the ‘magnificent 7’. I guessed 6 of them went 120-140 with one slightly smaller buck around 110.
