I’ve been shooting a 10” plate at 300 . I wouldn’t say it’s easy but, a good challenge. Sometimes it takes a little bit to get on target due to wind and my targets aren’t at exactly 300 each time but after that you can ding em fairly consistently. So much funI've shot a 12x12 with a 17hmr and it was easy. Shooting that same 12x12 with a 22 @ 200 was just as easy as the 17 @ 300. However, the 22 @ 300 yards was challenging.
I think 12x12 would be good for 22 @ 300 yards.
Agreed ammo is the limiting factor with 22. I shoot mainly match ammo and my gun will usually hold moa or better out to 200 once you get to 300 in my experience the ammo can’t hold up for many reasons but it’s still a hell of a lot of fun.A real good 22lr and Ammo will hold:
dime @ 50
golf ball @ 100
size of hand/index card @ 200
work boot box at @ 300 (solid 10-12" vert spread because of MV)
even if you have dead calm wind the velocity +/- of match stuff is the biggest issue
guys shooting smaller than that "all day"...shoot some 40-50 round groups and post...there wont be many
ammo is the biggest issue, some of the top benchrest guys only buy ammo off certain machines in certain facilities run by certain employees
Testing seems to be where it's at. Dialing a rifle in to the velocity it prefers, and then finding an ammo that is consistent at that velocity is the art. The tough part for .22's is many manufacturers don't post individual lot velocities. Eley does this with their higher end ammo, and I've found a few lots of Eley match that perform well, with a sub 30 ES. So, while I really like SK as a bulk ammo, I like using Eley because I can pick from the machine, lot and velocity. Yes, one can send their rifle off to an Eley or Lapua test center but where's the fun in that? I also believe that by lot testing on your own, much can be learned about the rifle and it's preferences.Better ammo?
Sadly Rob, over the past 2 years, I've found very few brands of rimfire
that are capable of producing an ES less than 40 fps.
That includes Tenex, R50 and Midas+.

Some bricks are decent, many are barely pistol fodder.
