`NATO if you can , find the Pyrodex pellets and use those instead of the 777 . The 777's leave a crud ring . For projectiles that dont destroy a deer but still knock them dead , I use the Hornady 240gr XTP Hollow Point that comes with the green sleeve . Or my other favorite is the 245gr or the 295gr Power Belt Hollow Point . Not the Power Belt Aerotip !. The Aerotip does not produce a great wound channel like the Hollow Points do . Every deer I've shot with any of those 3 projectiles had a more than sufficient exit hole and a deadly wound channel .
