I decided to crunch the data for a .375 H&H mag.
I selected a midweight bullet of 250 gr that produces about 2750 fps to make it comparable to the velocity and trajectory what is found in a .30-06 150 gr load.
.375 inches = 9.525 mm
Diameter of a 9.525 mm circle results in an area of 71.26 sq mm
71.26 gr powder – Reference powder weight based on bore diameter
83.0 gr powder – Hodgdon online manual max load for 250 gr bullet (this is the heaviest charge returned, and it is H4350)
83.0 divided by 71.26 = 1.164748807184956
3000 divided by 1.164748807184956 = 2575.66265060241
2576 rounds till predicted burnout.
I’m closing in on 63 years old.
Not many grizzly bears or elephants in northern New Mexico.
I think one of my sons will still enjoy shooting my rifle when they inherit it. Probably for the rest of their life.
