Working up some 338 WM loads - looking for max V with a 225 Accubond.
I got to about 2800 with H4831, and 2875 with H4350. I'm pretty much out of case room with the H4831 at 77.5gns (it is jammed in there, but good), a little compressed with the H4350 at 74.5gn.
There are no standard pressure signs - primers OK, bolt lift OK, no marks on the case head. Haven't mic'd the cases yet.
Rifle is a Savage 116, 24" barrel. Bullets seated out to max in the mag (forget the OAL), and are still 0.050 off of the lands. I have used the Tubb Final Finish (my experience is that this smooths the bore, and allows use of more powder for higher velocity w/o pushing pressure limits).
Question is - is there more opportunity with a different powder? Can this thing get to 3000?
Not looking to push way past the limits, but I do want every thing I can get. This is what I've got for LR work on Elk.
