The .224 Valkyrie is the latest cartridge from Federal Premium. Now that it’s been on the market for a few months, it’s attracting attention from everyone, from long-range shooters to hunters. I recently had the opportunity to run the Palmetto State Armory PSA-224 at the breathtakingly beautiful High Bar Homestead in Gillette, Wyoming. It was a good chance to find out just what the Valkyrie can do in shifting winds and on an uphill slant at long distances. End result? The PSA-224 was ringing steel at 1250 yards despite a major heat mirage and randomly shifting crosswinds at speeds ranging from 8 to 36 mph—the wind was whipping harder up the mountain where the target sat than it was at the trucks where I sat. The gun was loaded with Federal Premium Gold Medal .224 Valkyrie 90 grain Sierra MatchKing rounds and we were firing it from a bench using sandbags and a bipod for stability. A Vortex Viper HST 6-24×50 optic topped the rifle.

The way the gun was set up was not ideal for the stability needed for long-range shooting but it was possible to get it done with a little finesse; there wasn’t a spotting scope so fellow writer Ken Whitmore spotted me using the Vortex optic mounted to the PSA 6.5 Grendel he was running. With a different bipod and/or more sandbags for improved, consistent stability and a good spotting scope for increased visibility the PSA-224 could do even better.

The PSA-224 kept going even hot, dry, and dirty. I was impressed by its performance and by the range of the .224 Valkyrie. I’ve been running the PSA-224 complete rifle on the range at home as well. According to Palmetto State Armory the cartridge delivers as many as 127.88 inches less drop and 68.76 inches less drift at 1,000 yards. It’s certainly won me over.
