Do you know what fps you're getting from your MP40?[/QUOTE

I don't.

It's a question of taking it to the range when my mate has his chrono there.
Rarely coincide and I'm more interested in testing stuff that needs to be under 12 ft lbs.

Same with 7 1/2 Peacemakers that I still haven't done!

The MP 40 is adequate in my opinion.

Whereas the Mosin isn't.

Seems if most steel bb weigh 5gr to 5.4gr then the Umarex website claims 140m/sec .
Using an online calculator that gives 2.3- 2.5ft/lb
Doesn't sound great but wouldn't want to get hit in the a**** with a mag full

added :
Tried to see online what the fps is for the Nagant - none showing on those web pages I found but see the shorty Trench Gun Nagant does 427fps accordig to Pyramidair so using their calc thats5.4gr = 2.19 ft/lb
