I loaded up several different powder weights this AM, and went to the range- not too crowded today! Temp was 20 degrees, but no wind.
The last load shot was the heaviest powder weight, 82.5 gr. Chrono velocity was 3235 fps, and it shows some accuracy potential, as well. Cases show absolutely no signs of pressure, and this was a very pleasant round to shoot, as .300 Wby rounds go- noticeably less recoil than some of the 200 gr. loads I have been shooting.
Will try another half and one grain increases, if I get to 3300 fps at decent air temps and good accuracy, I'll be happy.
Doesn't look like it will take anywhere near 85 gr. to get there.
FWIW- a half grain powder increase gives 35 fps increase in velocity, at least it did today.
