Is it possible to meet these energy demands with black powder cartridge loads ?

1) for bullets with a weight between 138.9 grains and 154 grains the minimum legal energy is 2700 joules ( 1991.4 foot pounds per feet) at 100 meters

2) with bullets weighting minimum 154 grains, the minimum legal energy is 2200 joules ( 1622.6 foot pounds per feet) at 100 meters.

some common blackpowder cartridges:
.40-90
.40-100
.44-77 Sharps
.44-77 Remington
.44-90
.44-100
.44-105 Sharps (Necked)
.44-90 Remington
.45-82
.45-90
.45-100
.45-110 .
.45-120
.50-100,
.50-110
.50-140 Sharps
.450 Black Powder Express
.461 (.450) Gibbs
.500 BPE ( 440 grains bullet ,580 m/s)
.577 Express

In order for a 154 grain bullet to have 1991 ft lb of energy, it would need a velocity of 2414 ft. per second. I don't think that is realistically achievable with black powder.

A standard 405 grain .45-70 bullet would have to be traveling 1344 fps to meet the 1622 ft-lb standard. That may be do-able in some of the bigger .45 caliber black powder cartridges.

This one is pretty close to meet the demands:

45-120 SHARPS
500gr LRN bullet , BC 0.568, 120.0 gr 2F blackpowder, 1,170 fps muzzle velocity :
1112 ft/sek at 100 yards , the energy is 1373 ft/lbf = 1861.5 joule

How big are those deer in Norway anyway!

Do the officials there make you prove your ammo is legal or do they have a list of cartridges that meet the specs?

Yes, i think it must be possible to prove that a cartridge delivers the required amount of energy.

The energy limits i have mentioned are for big game.
