The Russian Mosin Nagant Forum

Over a year ago I loaded some 54r which I fired out of my M38. I got a really good tight group but I didn't bring my chrony. I'm hoping someone may have shot a similar load and could give me a ball park figure for computational purposes.

The load was:
IMR 4895 43.9 grns (A bit light I know)
.311 Sierra pro 150 grn SP
Graf brass, once fired
CCI large rifle primers

Any help is appreciated

There are ballistic computer apps on most the reloading supplier sites, You can plug your info in there and get a close SWAG.

Without the MV I'd just be guessing.
I'm still guessing if someone else gives me their results but at least I should be in the ball park.
I have interpolated from some other data found online though and I think I might be getting around 2,400 -2,500 fps which wouldn't be too bad since the load is pretty accurate.
I might just need to go out and shoot again to confirm it.

Sounds like you need another trip to the range with your Chrony. If I told you I think it is 2200 fps, or 1900 fps, it wouldn't mean anything really, then you have to consider the shorter barrel of your M38. If it groups well then at least the most important objective is reached- accuracy.
