RE: How is this....
Tripple Seven shoots great in some rifles. It makes a bad crud ring in some just above the powder column and restricts the ability of loading a second shot until the crud ring is removed. In some rifles a wet patch will remove it and in some it requires a brass brush and then several wet patches. You will just have to try it. It does have a little more energy in short barrels as the pressure rise rate is higher than the ascorbic acid based powders like APP, Goex Pinnacle, and Black Mag'3. In longer barrels I prefer Black Mag'3. My Omega hates Tripple Seven and performs great with Black Mag'3.
