Shot the .300 Weatherby today with a couple loads of R23 and R26., both under 180gr Accubonds
At least in my rifle, with these lots of powder, there isn't a heck of a lot of difference in burn rate. 82gr of R23 ran about 3180 fps, and 85gr of R26 went about 3280, with one reading at 3303...which may be a touch on the warm side.
Both were sparked by Federal 215M's.
Starting from a stone cold barrel, the first shot from the R26 load was right where I wanted it. The next two went about 4 inches higher
Let it cool off for an hour and repeated it with the R23 loads and it put 3 in an inch, and held zero nicely. Think I'm gonna tweak the powder charge a little and see if they tighten a little more. I'd be content with something real accurate in the low 3200's...
And next year, send to Pacnor for a new barrel
