MKnarr, I have shot sub 2" @ 100 with three of the five touching
A VERY calm day (NO noticeable wind) with my Anschutz and some rather expensive ammo. that group was two targets below my point of aim with my 36x scope cranked as far "UP" on elevation as it would go. Same gun and different ammo have shot a .6" @ 100 for 5 shots

OK, I'll admit that I did not read ALL 7 pages -- first 3.

Here's my question..
My 18" barrel 10/22 is sighted dead at 50 yards. Say I'm using some common Remington hollow point ammo @ roughly 1250fps?..

How much elevation (in inches) will I need to plunk one dead center @ 300 yards??

Anyone?

Iraqi Zealot Weapon of Choice

Someone on another forum recently claimed that the Iraqi zealot weapon of choice isn't a rifle at all -- it's an IED. Iraqis that point AKs at US troops are swiftly taken out with the US weapon of choice -- a 500lb bomb from an F16. That's how we got Al-Zarqawi, for example. The Iraqis we are facing now are the smart ones who have learned not to point AKs at us and have adopted tactics that are much harder to defeat.

At 300 yards a 22lr would feel like a little pebble hitting my Kevlar helmet

A pebble .... True, but ..... !

Yes Lad,

Using the example I posted above, it would be a very small pebble weighing only 37 grains, but ....

.... It would be travelling at 803 feet/sec and exerting 53 foot pounds of energy on your kevlar helmet .... might not penetrate but you'd sure have a sore neck for a day or two ... !

Exclamation Long Range 22LR

"Beware the man that has just one gun and know how to use it."

I believe this was said about Tom Horn, a real person in the late 1800's.
His weapon was a long barreled 44-40. (Arguably, a revolver cartridge)
For very long shots the shooter had to fire the round "like a rainbow,"
and hope for the best.

Hmmmmm . . .

How much energy does a ricochet have left?

I was told by a law enforcement officer that a bullet will lose about half it's velocity and energy after first impact, if it ricochets after that initial impact.

Does that sound about right?

Seems it would depend on the type of material it hit, at what angle it was deflected, and the type of bullet: Soft lead, alloyed lead or copper jacket.

Joe

I thought he used a 38-55 or something like that. Let me do a quick search.

Cheers,

Mark

Edit- Winchester 30WCF (Whatever that is):

Energy ... Momentum ... Conservation ... ?

Hi Joe,

Well, myself having attempted to forgo any real recollection of the principles involved since my retirement so many years ago, I'm sure there are amongst our members, current students of the earlier works of Leibnitz, Newton and Mohr, who with their modern computer-assisted technology, can provide all sorts of inexact answers to that question - lol.

But yes ... the answer can be approximated using some variation of the various Conservation of Energy and/or Momentum theorems assuming the correct input data is predicated.

Regards,
Bryan - The Fuzzy Limey

His son is here in Division and is a hell of a shot too.

I used to regularly shoot out to 300 with my 10/22. Had great times shooting a 10" steel plate. As for the effectiveness on a human target, forget it. Unless you hit an eye or got a lucky shot into a major artery you aren't going to do any damage at all.

Dad and I watched my 75 year old Grandfather take a Remington gallery pump with "short" ammo, open sights, lean up against a water cistern and drop a chicken eating dog at 200 yds with one shot back in about '63. Dad and I just looked at each other. Granddad says, "That ought to take care of him" and put the gun back on the rack. I think one of us mumbled something about good shot. M1911
