I'm a member at BRPC and use the .224 Valkyrie (on a Windham 20" Gov't lower) and my Colt Match Target (.225/5.56) regularly at the Silhouette Range which is 212 to 960 yards. (there is a new further target but I haven't tried that one yet). On the silhouette range I rely on the ping and target swing out to the sheep to know I hit the steel. Or in two cases I actually put the last bullet into the chain and dropped the tank, thankfully there was just two of us so we could drive out and put the tank back up, you can hear the tanks better when you hit them than the plates, but man they have a LOT of sharp edges. The 840 and 960 my friends spot for dust around the targets for misses (and yes I do miss!), unless the wind is blowing just right toward the shooting benches you normally can't ever hear those ones without using voice activated radios taped to the back of the steel and we can only do that when we get out there real early or real late to drive to the targets.
For sighting in and short range shooting there is a 200 yard AND meter lane on the public side of BRPC and I dialed in my rifles at 200 meters there. Shooting from the bench on sandbags (neither rifle has a bi-pod but I am thinking of going that route) at 200 meters it is easy to keep either of my long range guns in a 4" square grid with about 25-30% in the 1inch bullseye.
I still need to try the Valkyrie at one of the 200/300/600 matches so I can get some paper to see what kind of actual groups I can get with that rifle beyond 200 meters. I'm out of town this weekend so I won't be at the match on the 28th but I am hoping my show schedule lets me compete at the end of May. I already did the bullet drop calculation for 600 yards and ordered a custom elevation dial from Leupold for the scope that will live on that upper.
If you're a member at BRPC you probably are familiar with the silhouette range but here's pics of the known target distances and the sheep with the tank I dropped and put back up twice... The tanks alongside the critters are some recycled compressed gas tanks of some kind, nice ping to them.
