Wanted to see if anybody has any insight on my load data:
The VV load manual lists 3.8gr N320 @ 1.142" OAL for a 124gr plated bullet will give 1000fps out of a 4" test barrel.
I loaded 3.7gr N320 @ 1.080" OAL, 125gr Xtreme plated FP. Shooting out of a 4.9" barrel (Beretta 92), it feels really soft and was quite accurate but I'm afraid it might not make minor PF.
From what I have read, the difference between a 4" and a 5" barrel is around 40-50fps and it looks like if I interpolate the load data, each 0.1gr of powder is roughly 20-25fps. So, THEORETICALLY (my theory at least) is that I should be around 1015-1030 fps (1000- 25 + 40)which would make PF, barely. However, I don't have access to a chrono to actually verify this.
Has anybody loaded something similar and can provide some insight?
I also loaded some at 4.0gr N320 which had much more recoil and didn't seem as accurate.
