On the road again
I am not a huge 22LR fun but sometimes I shoot for fun. I was putting together a note with some long range simulation scenarios for a friend and I figured lets put some of the number here in a post.

22LR it is prefect for long range simulation that can be done in 200 and 300 yard range if you want.

61 inches at 200 yards is roughly 30MOA adjustment. May scopes can take this. A decent scope w/o braking the bank is a must and for 300 yards you might need a 20MOA rail too.

Average 40gr Jacketed Round nose form a 20" barrel is:
1260fps
BC: .134

Yardage and Drop vs what can simulate like a military rifle load...
50 yards 3.27 simulates 100 yards
100 yards 13.58 simulates 200
150 yards 32.37 simulates 350
200 yards 60.91 simulates 450
300 yards 151.96 simulates 700

So the trick is to build your ballistic charts for every 25 or 50 yards. Move the targets and adjust for elevation and drift and hopefully you will have the math right and a good scope
and you can have a lot of fun in this long range simulation. Write down your corrections and this 'exercise' will help you with any caliber. Keep in mind that drift is considerable so
I will not try on a day with wind over 5mph.

Tested with a Savage MARKII FVXP with accutrigger and bull fluted barrel that I picked up at Dicks a couple of years ago for $260 and prints sub-moa groups all day long. (with good LR ammo of course).

Over the years I have found I can make 100 yard shots with my 512 Remington 22 rifle. But it has to be pretty windless for me to try them. At the Range I can get 10 shots in the bottom of a 12 oz soda can at 100 yards.
I never tryed to do the math that I was taught in Marksmanship Training. I don't like math that much. But I might have to give this a try.
 
Wouldn't it just be easier to get something in a .308?......:D





(all kidding aside, I'm gonna try this with both the Marlin .22wmr and .22lr next time I'm out at our gun club. We have one range that goes out 450 feet, which should be kinda fun)
 
I like to place steel plates at 200 yards. I'm not so much worried about the elevation as reading the wind. It's amazing how much that bullet moves in much wind. Makes it fun to shoot on a gusty day. Nothing to bring home and post online, but certainly more educational than shooting at dusk or dawn in minimal wind.
 
You can avoid running out of elevation in the scope by using two targets. Aim at the top one and hit the bottom one.
 
Howard,
that is a nice trick
In any case the whole point originally was to get my friend to practice the math and map the field resutls to the chart and play with the scope adjustment. A shot a 300 yards is like a 700 yards or so shot with a military round. So that is why I call it long range simulation.
A nice fun way of doing it also saving some money with more affordable ammo.

Cheers,

I've been told that shooting 100 yards with a .22LR is like shooting 600 with a Highpower rifle, and 200 is a pretty good simulator for 1000. I've practiced a little with a smallbore rifle prone at 100-yards before, and I think it's harder than 600 with a .223 in my Service Rifle.

The only other note I have is that most people recommend using standard velocity or target ammo in the .22LR for extended-range shooting. It avoids the transonic transition as the bullet drops for supersonic to subsonic as it goes downrange.
 
I've been shooting my .22 out to as far as I can and using HV ammunition doesn't work very well for me either. It shoots very well at 50 yards, but at 100 it's all over the place. I try to shoot nothing but some form of sub sonic ammunition when shooting beyond 50 yards.
 
While this is true, I have found that non-subsonic ammo is not accurate farther than ranges between 50 and 100 yards. If you use something that hovers around 1050fps you should be good to go, but that will change your drop data.
 
I love trying to stretch the .22 out a little from time to time. It's fun, challenging and rewarding when you finally get it dialed in.
 
Norrik,
Yes when a bullet goes from supersonic to subsonic it rattles a little and this causes the groups to vary. I have observed that with a submoa rifles, a good bullet in 22LR varies around .10-.20 MOA because of this. A good rifle with a good load can drop many tennis ball size groups at 200 yards which is ok for most hunting too with this type of laods. I found the biggest issue is the lack of consistency more than the break speed issue so if one can stay away from the value packs the consistency will show. Nothing wrong with burning some value packs for fun but you will have some puffins once in a while that will be all over the place.

Speed of sound is 1,126 ft/s in 60F dry air.

Cheers.
E.

I've matched my brother hit for hit with my CZ-452 out to about 170 yards. He was shooting an SMLE. The CZ's sights really help for this type of long range plinking.
