Not intended as a pi**ing contest

[finnbear270]

Just wondered how far your favourite deer load is legal to? Having been developing a load in my 7mm WSM recently, I have just run the numbers through a Hornady ballistics program, the present load of 69 grains Ramshot Magnum under 162grain bullet has given a figure of 1700 ft lbs of remaining energy at 500yds, just legal in some parts of the UK, As in the title................. not intended as a p*****g contest, just genuine interest.Steve.

I have always been under the impression that the miniimum energy requirement was observed at the muzzle and not on target .
Anyway energy transferred is a mathematical function of speed on arrival minus speed on departure through quarry species and bullet weight .
This varies according to bullet construction and target mass , a complicated state of affairs .
In the words of the late Robert Ruark `use enough gun.`

HWH.

Stag, you are correct in your statement that the measurement is taken at the muzzle, just trying to get a feel for the degradation of the energy side of things. Steve.

...that'll be about 50yards with my 6.5x55 with 20inch barrel and low recoil home-loads!

Replying in sense of fairplay and I do not use this calibre for deer, unless I was in immediate danger !

825yds - 1705 ft lbs 250g bullet

Come on!, spit it out, what was it?

338 Lap Mag

Thought as much!............ Turbine tw****r!

He he he





every time I squeeze the trigger

Redmist,
just curious, how are you in danger @ 825yds

My cut off point was 1000ft lbs which is about 900yds..

Well you never know, it could be armed, it may have access to a keyboard therefore still "dangerous" 000's of miles away


The answer to the post was in jest,


The 338 isn't passed for deer, just a "range" gun, in fact a "very long range" gun

Maybe a minaturised version of the V3 'England Cannon' in the deer calibre of your choice would keep the energy levels up? Fin(n) stabilisation optional of course.

Seem to remember some people recently getting into bother trying to export parts for a very similar device, Sheffield forge perhaps?

Or Matrix Churchill perhaps?
