Minimum energy for deer / 250-3000 and 95 LBT LFNGCs

[fremont]

Keeping the velocity south of 1800 means muzzle energy <700 ft lbs. Meplat = .150". Surprised it was so low. Energy is < 300 ft lbs @ 200 yards.

muzzle energy is meaningless.

bhn x 100 = impact velocity
If your impact velocity (not muzzle velocity) stays higher than BHN x 100 then your bullets should expand. The higher the impact velocity over the BHN x 100 the greater degree of expansion.

for instance,
12bhn x 100 = 1200 impact velocity(fps)
15bhn x 100 = 1500 impact velocity(fps)
10bhn x 100 = 1000 impact velocity(fps)
and so on.........

We have energy minimum requirements here where I live , on the other side of the pond.

I remember when I bought my first Marlin for moose hunt,I had a dog so it was always close range. Marlin is very practical for a dog-man. I quickly realised that any available 45-70 factory ammo was not moose-legal. We need minimum 1475 foot-pounds @ 100 meters. Light bullets require 2000 ftlbs.

That was 20 years ago,nothing has changed. Reloading is still the answer. Remington 45-70 405 grain factory ammo is not enough for finnish moose.

For whitetail we need 1250 foot-pounds @ 100 m when the bullet weight is 125 grains or more. 90 grains is minimum legal deer weight,then the energy requirement is 1475 ftlbs.

Interesting,huh? :)
