# Thread: wanted help to calculate if deer legal

1. ## wanted help to calculate if deer legal

Hi all.
could someone please give me the formula for working out if a rifle is deer legal should I know the mv and the bullet weight.
Kind regards
Jimmy

2. velocity x velocity x bullet weight then divide by 450240 = ftlbs

Not enough info! It's no use without defining the units! Please do confirm!

Velocity in ft/sec ?

Bullet weight in Grains ?

What calibre? If a factory loading in that calibre meets the minimum legal requirements of diametre and energy thats all you need to know.

Ian.

6. Thanks for the help guys. Basically what it is, I have an 18in barrel 6.5/47 that I shoot 100grain bullet with and I was thinking of using something heavier but due to the loss of mv caused by my stubby barrel I wanted to work thing out to stay on the right side of plod.

Jimmy 6.5x47 with a 100g bullet or more will easily be okay, the police have neither the time or the resources to go about examining bullets retrieved from shot beasts or chronographing your handloads to see if they meet minimum specs, factory ballistic data tells them all they need to know.

8. Thanks but like I said I was wanting to go heavier and slow things down so I get less hydro damage, I was thinking of chronographing some 140 out of my stubby tube then trying to work it out.
get ya point regards police resources but just for my own piece of mind and all that, plus I just like to know for knowing sake.
Regards
Jimmy

Ian I am surprised that the Scots boys haven't jumped on you yet, you forgot to mention the minimum velocity requirements north of the border.
