24.5 gr H-335, Win SR, PMC cases, and 55 gr bullets... for blasting I use the Nosler SPs, and for 'yote cappin I've been using polymer-tipped 55s (NBT or VMax).

This is out of my 1 in 9" twisted M4 and I haven't chronoed it, but it is quite accurate.

It is below max but I don't know what changing out components would do, so be sure to consult Hodgdon's manual, go to start and work your way back up if you decide to utilize.

I'm trying out some of that new copper build up powder this week w/ 55 gr NBTs... should be interesting...
