Noob question on targets
So I'm finally taking my new AR to a friends house who owns some acreage and we're going to put some rounds through it and a bunch of his guns. He has everything from an old .22 to a M1A1, 30-06, etc. What I'm wondering is what should I shoot at with my AR?
He has some paper target holders, but I was wondering of any of those circular targets with the auto resetting flipper will work with the AR. Most of them are rated to a .22 but others are for handguns and slugs.
Basically I'm looking for something fun to shoot at and something him and I can compete with. Total time for all targets, side by side comp, etc.
