Will it fit with some ✨ persuasion ✨?

direct energy measurement is only needed to catch the ".2's honest guv'" crowd

I guess it depends what the concern is.

If it's reality then we should be measuring energy with as few variables as possible.  And testing what people are actually using in the field, not at the chrono station.

Anything else is just one form of theatre or another.

dug up the old spreadsheet:

if we assume that the site limit is 350fps (1.14j) for non-MED

then using 0.5g bb's:

a 440fps (1.8j) dmr is going to need 12.94m MED

a 500fps (2.3j) bolty is going to need 20.28m MED

so for the sake of argument if a given site has a 10m MED for 1.8j then a DMR gunner using 0.32g is going to be hitting less at his MED than a rifleman could point blank, but if he used 0.5g (the heaviest available) then he'd be hitting slightly harder.

Given that I've not been to a site with less than 20m MED for DMRs (30 for BASRs) I'd assume that would comfortably cover any worst case scenarios as far as ludicrously heavy BBs goes?

for those sites yes.

i picked those numbers mostly to highlight the potential for the case rather than being strictly representative.

Fair enough, I guess you'd have to use some pretty heavy BBs at those ranges to be anywhere near 1j on impact and I daresay they be so slow you could send written notice of them!

Accidents (actual accidents, not Arec Barwdrin "accidents") do happen though.  I've boltied someone in the bare arm at about 5m when they pointed from behind a building just as I pulled the trigger.  Soooo much "Sorry, mate, my bad, mate".

Fortunately it doesn't happen often, and I reckon UK energy levels are actually about right.
