Those are the numbers from this years Safari Rifle Challenge in Libby, MT.

When people signed up I had them put down their rifle caliber and bullet weight. So just for kicks I went to the Hornady websight and got the energy numbers.

58 Shooters each firing a 20rd course of fire is broken down as follows.

One shot from each of the shooters totalled 268,902 foot pounds of energy and 22,445 grains of bullet down range during one scenario.

A total of 20 rounds by each shooter equaled a whopping 5,378,040 foot pounds of energy and 448,900 grains of bullets down range (at 437.5 grains per ounce, that equals 1026 ounces which is just over 64 lbs!).

The cost of all that ammo - unimaginable

The smiles on every face during the match - PRICELESS!

Lots of lead...a new EPA Super-Fund site!!!! :-)

New Jersey RULES on Those... [S-F-S]

For sure!

Our previous ruler, sent me 18 416 Rigby rifles, and 18 scopes.

He wanted the scopes installed and sighted in one day!!

I had to fire a total of 96 rounds to get them sighted in!!

That was 38,400 grains and 491,258 foot pounds of energy!!

I used a bag of lead between my shoulder and the rifle stock, but still got a headache!!

Just in case I got the figures above wrong, the ammo all was factory made, 400 grain bullets, and I assumed a 2,400 fps.

They all laughed the next day when the rifles were ready!

One man stated that the only reason I managed to do that was the fact that my head contained only lead shot - not brains! A description given to me years ago because I shot so much!

Holy cow!
I am wondering how the need for 1-day service on sighting in 18 scoped rifles of .416 Rigby flavor could arise?

I suspect it was a prank that Walter had something to do with, and he and your "Ruler" were in cahoots on this.
They got a good laugh out of your headache!

Yes, I have no idea of the goings on with your "Ruler."

96 shots for 18 rifles to get the scopes zeroed:
5-1/3 shots each, on average.
Zeroed at 100 yards with 400-grainers:
First install 18 scopes on 18 rifle.
Bore sight each one.
Fire one shot and then adjust the reticle to the single bullet hole and try again and again.
18 times again and again!
Not a bad days work when you can get it.

Which certainly begs the question of why did he have 18 identical .416 rifles and then why did they all need to be sighted in at one time. Was he hosting some type of hunting trip and also supplying all the guns?

Like most of us here, he enjoyed shooting so much he had both a rifle range and a clay shooting range close to where he lived.

I am not really sure what the deal was with these rifles. They might have been for presents to other shooters.

One time he sent over 5 identical 270 Winchester rifles made by Mannlicher.

He sent scopes and ammo, again to be fitted and sighted in.

All the ammo was from Norma, 150 grains.

That is when I discovered an amazing fact, after shooting them over the chronograph.

The rifles were from the same manufacturer, same model, with the same ammo.

The difference in velocity from the slowest to the fastest was about 150 fps!!?

That kind of variation is amazing, but I suppose it should not even be surprising.

A thousandth of an inch in the rifle business can make a world of difference.

So, send me the fast ones that shoot straight and work all the time, please.

If the 58 were 585HEs be about 13 million ft lbs...........Ed

I was also surprised on this as all rifles and ammo were identical.

I have had other rifles, of the same caliber but different make, which had quit an enormous variation in both velocity and maximum charge that they will accept.
