burntmuch,If its that tight you should be all right if it loosens up after 3 or 4 hunderd shots you many need to use HPH24; thats where I am at.
gleason.chapman, 100yds on the Cleborne county club Range off a bench rest. tis amazing how much more shooting you get when all you have to do is load and shoot. I have been noticing that it dont heat the gun up near as fast as 777, which also helps I shot that one hole group with out any cooling time at all in 74 degrees. Lee
