I think dispersion due more to wind...

I think dispersion is more due to wind than differences in velocity. I think the horizontal displacement kind of indicates that.

Might be Dave.
No conditions shown on target so no answer for that thought.
Vertical I believe is due to mv spread as the high and low are in the vertical line through center.




Unless he was dealing with a tailwind.
That kicks my adze every time.

I felt pretty good about it, early in my time with the 1717D, it initially did not like to get very dirty...noticeable fall off after 50-70 rounds, now its more like 150.

Considering that and the fact that each target required some adjusting of my Cowan Rest may well account for some of the vertical, and rushing toward the end certainly didn't help. No doubt many here could do better. The composite target is interesting but on its own and without accounting for a couple of variables means.....NADA.

Just came across this practice target that I shot a few years ago.
I have a rimfire match called the "Wile E Coyote Rimfire 100" that is shot at 100yds.

Shot the 1st target with 20 rounds of CCI TNT into a copy of the match target.
Bull is 1 inch.
I was going to shoot another 20 into the the 2nd target, but stopped after 5 shots because of how small the group was.


The targets were shot with my Anschutz 1727F know as the ("Hammer").
It's my most accurate rimfire by a mile, and I rarely bring it out of storage.
It has 2253 rounds down the pipe, and .17hmrs barrels start to loose their edge somewhere around 10,000 rounds. So I'm saving it for matches/contests that are really important to me.

Here''s its best group ever, and a 10 bull USBR target that I shot on my 7th attempt.

Scoring a 100 on this target and taking out the ten ring for an X, is much harder to do with a .17 compared to a .22 because the hole is about 33% smaller.

So my point is the .17's can really shoot if you get a good rifle, along with a decent batch of ammo (of which I've had many).

This is the rifle as shot with the exception of the rest. All targets were shot off a Bi-pod and rear bag.

Thanks guys!

So Jala is one of my very favorite miscreants on this site, but man-o-man does he have the worse luck with his .17hmr ammo.

Maybe because I've never chronographed any of mine, I've just naively believed it's not all crap.

I've been described as easily entertained, an annoying old coot, a curmudgeon,
a cynic, even an opinionated pain in the rear, but never before a miscreant.
Thanks Smooth, I appreciate the sentiment.

I can not disagree with y'er diagnosis of my luck with rimfire purchases.
Better it be me than everyone else. At least it keeps me occupied
and doesn't interfere with those who actually need accurate rimfire ammo.

And, it's educated me in just how many ways rimfire can be affected
by problems in the methods of manufacture and distribution.

I'm honored to have added another descriptor to your long and well earned portfolio.

Science and facts still can't figure out how bumble bees fly.

Sometimes you just have to go with the "Force".

I just will my bullets to hit where I want them to, **** the science.

Interesting read.

Well I have replenished my 17hmr ammo and ready for the 3rd installment of test since nothing is really conclusive so far. Although I have eliminated Winchester and one type of CCI. For now Federal is the leader after two rounds of test. Trust me...that's not saying much.

The ultimate 50 yrd test imo is spent 12 ga. shotshells laid over on its side. If you can put a hole in the brass at 50 yards consistently, then the combo of you, the ammo and the rifle are a good match. Extra brownie points for all primer hits.

+1

I confess ... after a paper punching exercise, the shotshell test is how I prove to myself that all is well. And yes, punching out the primer is a thrill, one I enjoyed recently with a Sako Quad in 17 Mach 2

Enjoy!
