Ya know Stang, the times I've used 4064, the shot ends up about 14" above where the 4350 hits. Obviously it's a bit faster burning & FPS is up there (never chrono'ed any of them) but accuracy just isn't there. Even with my 25.06 the 4350 has been the powder of choice for one hole groups.
I can't express how glad I am to be able to shoot my beloved '06 again. The shoulder surgery I had last year won't allow me to shoot without the muzzle break. The ONLY downside to the break is guys at the range that have the misfortune of sitting next me have introduced me to a few new curse words. I had one guy come over & ask if that was a 50BMG....(hehehehe). Even the Savage factory break on my .308 has been described as "brutal". I heard that used while I was helping a guy pick up some of his stuff that got blown off the bench from it (again - hehehehe).
Tomorrow - to the range. This "being out of work due to back injury" stuff ain't so bad.....
