The .204 Ruger is the highest velocity round available in the AR-15 platform and is a terrific varmint cartridge in either AR-15s or bolt action rifles. It has essentially no recoil while providing velocity above 4000 fps. This cartridge was developed by the good folks over at Hornady®. We load the .204 Ruger using the 32 grain VMAX™ bullet, which provides a great combination of high velocity, devastating effect on varmints and sub minute of angle accuracy. Varmints now have yet another thing to fear from Black Hills!
