Screaming rounds that fly at 3,600fps out the muzzle with a 45grain Notched JHP round. This Ammo is awesome on Paper and targets but a heck of a lot better results on med to small sized game! Also awesome Predator round, a bit of pelt damage where point of impact otherwise nothing crazy or out of the ordinary with a JHP bullet. I recently Shot a nice sized Coyote at 237yards away with one shot to the lungs and the 57pound Yote dropped dead in his tracks, a rather very humane kill and I walked away with a nice pelt. I noticed these rounds are best suited for within around 300yards for optimal kills but then again a kills a kill, I noticed the 45grain rounds start to loss a lot of their energy as their mainly intended for varminting. Thanks Impact you guys Rock!
