I think I've come up with a useful scenario...maybe. :rolleyes:

50 shots at 200 yards, rimfire, whatever setup makes you happy.
22lr, 17 hmr, 22wmr, 17hm2, 17wsm, all brands, all types.
Full benchrest setup, bipod, bags, or one-piece test rest, it doesn't matter.
Grab a chunk of cardboard, about 14 inches by 24 inches,
set an Aimpoint at the top/center, and dial y'er scope up
so the POI is about 10 inches down from the Aimpoint. (5 MOA).

Post a picture of the results with a 12-inch ruler alongside the 50-shot group for reference.

Include a pic of the setup, the box of ammo used, and if you have a chronograph,
the high, low, and average muzzle velocities of the 50 shots.

To avoid having to hunt the entire thread,
in order to find the results with a specific brand of ammunition,
the links below are in alphabetical order by brand name and type.

### indicates the best results so far

You can calculate what the results will be at lesser distances by applying the half-third rule.
Half the distance produces a third of the spread.
At 200 yards the 50-shot group measures 9 inches of spread.
At 100 yards expect 3 inches of spread, at 50 yards you'd get 1 inch of spread.
And at 25 yards expect 1/3 inch of spread for 50 shots.
Useful if you are looking to compare the results for accuracy at lesser distances.

For comparison to results at 100 yards, see the 50 at 100 thread.

To review results produced at 100 yards in a testing tunnel see the 25 at 100 thread.

I should try the 50 with peeps now that I have a separate target I can see. There were some really impressive groups shot with peeps last weekend.

4 inch is pretty good, 3 inch would be bragging rights due to the fliers. I'm guessing around 5-6 inch with the peeps. Need a nice day to try it.

There ya go using facts and logic and ruining my perfectly good explanation. :D

I was thinking my results are so amazing, others felt it wasn't worth attempting. :rolleyes:

When shooting at public ranges, especially combined distances,
It is annoying having to wait for targets to be set or retrieved
when you need to make the most of your time. I'm lucky that
the local club has separate 50, 100 and 200 yard rifle ranges.
The 50 and 100 get the most use. The 400 yard round trip
is a fairly strong deterrent for most shooters. My range mornings
usually find me the sole shooter on a 7 position 200 yard setup.
 
#114 ·
I'd love to do this, and will give it a try sometime. I used to shoot mini-Palma back when it was actually shot at 180, 190 and 200 yards, so I have some affection for shooting .22LR long-range.


Affection, or maybe better called infection????


I'm jealous of your situation … a solo day at a 200 yard range sounds like Nirvana to me!
 
#115 ·
Im fortunate to have a friend with a 200yd. well kept range, but he is 2 hrs away. When I get a chance to go for an ‘unscheduled’ weekend this would be a good thing for me to do. I will need to decide which rifles to give this a go with. Im working mine out at my home 50yd range so it would be interesting to see how they, their prefered ammo at 50, and me fall apart at 200.

Added a third support point to the barrel block Bmag.
Barrel is locked down, receiver is free floated.



Federal American Eagle 20 grain 17 wsm
9 five shot groups after using 5 shots re-zeroing the scope.

Results of 9 five shot groups:

1.30 inches, 1.53, 1.32, 2.40, 1.55, 1.65, 2.20, 1.22, 2.45 inches center to center, 1.73 inch avg.
Horizontal spread is me misjudging wind and catching a gust.

Sellier & Bellot 45 grain copper plated 22wmr
made in Czechoslovakia, flat nose, rated 1560 fps



Visual inspection shows scraped or chipped copper plating
and many dents/dings and even creases on the bullets.
Seating depths of the bullets and seating angle varies.
Muzzle velocities as measured: 1768 high, 1702 avg, 1660 low



10 inches of vertical strays, 8 inches of horizontal

Winchester Varmint X 17wsm 15 grain lead free, 3300 fps
Barrel Block Savage Bmag, Sinclair bipod, wind 8-12 mph from my 8



49 rounds fired, 1 fail to chamber
couple thousandths excess diameter at the shoulder prevented complete chambering



3.5 inches of vertical, 4 inches of horizontal
pretty good with the left to right breezes



15 grain ballistic tips cost less than match 22lr
4 inch group at 200 yards, same results as match 22lr,
except for the one out of spec cartridge.
Winchester quality control missed that one.
 
#119 · (Edited)
I have avoided the 17s for years; now Im getting interested from what you are showing. I was put off by comments about the 17s being ‘more sensitive to wind and thought I didnt need that. You are showing that you can get equal or better than match 22lr at 200, and about all I do is punch holes anyway; a 17cal.hole punched in the right place would be fine.
 
#120 ·
I like the 17's.
For rabbit control at the farm it's a very effective cartridge.
The rimfire 17's aren't precision target rounds, but with minimal recoil
it's an enjoyable way to spend a morning at the range
without spending a lot of time and money at the reloading bench,
or a lot of wear on a match barrel. :D

I can see the bottom of the storage locker again.
Most of the random boxes are gone.
One small problem....I'm enjoying the 200 yard rimfire shooting.
No, it doesn't produce the tiny groups hand load centerfire does,
but the skills needed to make rimfire stay on paper at 200
are the same as needed to shoot sub-moa at 450 with the 223.
It's addictive and inexpensive. I think I'm going to expand my selection
of ammo and order one of each of the different brands/types not already tested.
CCI, Winchester, Remington, Hornady, Lapua, Eley, RWS, Norma, SK, Wolf,
ought to keep me busy for another year, at least.

I'm easily entertained. :rolleyes:
 
#121 ·
Okay, time for a giggle....200 yards, attempting 50 at 200 with a 22lr semi-auto pistol.
Buckmark Varmint, heavy bags, EER scope, Fiocchi Standard Velocity, 1070 fps made by CCI.





That is about the fastest way to burn through 22lr I own. :D
Load 10 in the mag, acquire and squeeze 10 shots as fast as is safe.





Aiming at the old Lapua tray and as can be seen, I am a horrible pistol shot. :(
The sad part is, I really was trying to hit what I was aiming at.
Can't blame it on the ammunition, just lack of skill. At least I stayed on paper. :rolleyes:



The muzzle velocities as measured were pretty tight, better than average.
Doesn't help when the trigger operator lacks the abilities needed.
Still had fun making the attempt. Obviously need more practice.
Good thing I've got lots of bulk 22lr that can be used while doing so. :D

Winchester Super X 40 grain FMJ 22wmr, rated 1910 fps
CZ 455 Feddersen stubby, heavy bags



Shoot 5, let the barrel cool, shoot another 5, let the barrel cool,
leaves time to inspect the ammunition while waiting.
Flat nose, copper plated, visible defects on some cartridges
Varying seating depths, canted bullets, dented brass, worst one below



Didn't expect great results, didn't get them.



Not all rounds stayed on the backer.
I count 3 missing holes, no telling where those bent bullets ended up.
 
#124 · (Edited)
200 yards, wind from my 2 at 8 to 17 mph
Federal AE 20 grain 17wsm (made by Winchester)
BBBmag on the Sinclair with the chrony out front.



Ten 5 shot groups



1.60 inches, 2.32, 2.23, 1.95, 1.85, 1.62, 2.10, 2.0, 1.26, and 2.05 inches center to center

Overall aggregate vertical spread 3.8 inches, horizontal 2.9 inches.
Pretty decent for a varminting round with the wind chuffing at 8 to 17 mph.
As good or better than match 22lr at 200 yards.
 
#126 · (Edited)
No, but you do...so why not shoot a 50 at 200 and post it? :D


I can use the help...so many types of rimfire, so little time! :( :rolleyes:



At the bench this morning, I was asked where is the original Fuglie? :eek:
Wouldn't take but 5 minutes to install the Feddersen 22wmr stubby into a barrel block.
Might make for some interesting results from a NOT free floated barrel, eh?

Side note, Federal 22wmr is relabeled CCI 22wmr.
Federal contracts with CCI/Speer to manufacture 22wmr and 17hmr.
Only the headstamp and labels are different. Same cartridge off the same machines.
 
#128 · (Edited)
The chronograph is a convenience, not a necessity.
Shoot the 50 and post the results.

Careful though, you might find it addictive and end up like me. :eek:

50 and 100 yards bore me. 200 yards with wind and rimfire ammo is a hoot.
With a pistol, it's downright funny. :D

This morning after playing with the BBBmag
Federal Automatch and the Buckmark Varmint at 200 yards



Most stayed on paper, but not all. :(
I really need more practice.
Lots more practice. :rolleyes:



One thing I noticed with the pistol, mv spread is much less
than with the same ammunition chronied from a 20 inch barrel.
No idea why that should be so.
Why would barrel length have any effect on ES?
 
#131 ·
The increase in V ES in longer barrels is because friction is a significant force on the bullet from about 6 inches on. Friction robs the bullet of a given amount of energy per unit length traveled up the barrel. But, the energy of the bullet goes as the velocity squared, so slower bullets will slow down quicker than faster bullets. This will lead to an increase in ES with increasing lengths of a barrel.

#132 ·
Thanks Landy.
First time it happened I thought it was a chrony malfunction.
Tested with rifle and typical bulk ES displayed as expected.
Tried again with the pistol and again ES significantly smaller with the same ammo.
Surprised the heck out of me.
I've been thinking about the pressure gradients as the bullet travels down the barrel.
Volume behind bullet is increasing, friction I think is a constant relative to surface area,
so as pressure decreases and friction remaining the same... it's messing with my understanding. :(. :D
 
#133 ·
Velocity as a function of barrel length

I found this site, but it seems inconsistent with all I have read before on the subject. All the writers have said the optimum barrel length is around 16 inches and velocity declines after that due to the fact the powder is no longer expanding and the bullet still experiences friction. With the figures published here I conclude that the ammunition is being made with slower burning powders so as to achieve higher velocities without raising maximum pressures, useful in the longer barrels and better for high velocity bragging rights which sell products. It would be interesting if someone with some standard velocity and high velocity ammo made 50 years ago would do test with it and contrast the results with today's equivalent ammo. These new figures seem to show maximum velocities at about a barrel length of 22 inches.
