Mine likes 27.5 grains of BLC-2 and 55gr Seirra HPBT's. Shooting great on paper and works great on varmints to.
BTW, forgot to mention this, last time I gt 1,000 rounds new batch of brass, I weighed them and sorted them by weight. I really don't mess with measuring cc's of water, on my AR-15 ammo, like I do on my 22 BR benchrest brass. I just tossed the ones that were .5 grains below & over, and then trimmed the necks square and cehcked to see if the necks needed turning. After every 2nd resizing I check the brass OAL to see if I need to trim them, if they do need trimming I trim them. Some case have been reloaded 10 times at least, still using the same brass for the past 8 years or so. Whne I get down to about 250 peices I'll order another 1,000 and go thru the wholes process again.
