I think the groups will tighten up when I use the sandbags, I could not get a good steady hold in my mechanical rest. This is the first time that I have used T7. How many shots do you take with just using aspit patch between shots?
With my Knight Wolverine LK-II I have had range sessions of 40 shots with just spit patching. With my Black Diamond XR I have to break the striker down after about 15-20 shots and wipe the rifle out real well or the striker gets all fowled. On the Disc I have shot 15 rounds and then I like to break that down too and clean out the bolt area a little.
As long as your rifle will fire and you can seat the projectiles, technically you can shoot until your tired. Triple Se7en is a clean burning powder. If you're not getting a hard crud build up, you have it made. Just keep shooting..
I just bought a new Dead Shot rest by Caldwell and I really like it a lot. Although I have to make some modifications to my platform in the spring..
