I use mostly 12" round plates out to 500 yards, but theres a few 6" at 300 meters.(since its a home range based around natural back-stops there's some odd ball distances involved and a mixture of yards and meters.) At 500 and out to 800 I use IPSC silhouettes, but there is also a 18" by 36" plate at 500 that is very popular because its hard to miss completely due to wind. If a guy is feeling good he can always take the headshots. For the most part we're aiming at painted marks on the plates and can see the hits on the paint, so really the bigger the better for the actual plate. Its frustrating to not be able to tell where a miss went. I welded 4 square plates together to make one oversized one for 800 but if 4 x 8 sheets of AR500 weren't so crazy in price I would have done that.
