OnTarget TDS. You can download a 15 day demo and it will build composite groups. I built 120 shot composite groups a couple weeks ago. And you can export to excel to geek out even further.

I haven't looked at any of the data too closely yet, and I fully expected the data to be poor quality due to the short distance. My priority was to collect and compile sample data while I had an opportunity and my OnTarget TDS trial was still active. The chronograph errors should be a relatively...

Although certainly tangential to the original post, I've been exploring OnTarget TDS and statistics beyond group size based on maximum center to center measurements. I'm not sure what I've learn applicable to comparing my groups to others on-line and I'm not sure what I'll settle on as...

The concept has huge potential, particularly the automatic detection of shot location relative to aim point with the predefined targets. I'm hopeful the auto shot detection works well. I've played with a target image from my lot testing with manually identified shot locations and exporting to...

From this latest exploration of 22lr accuracy, my conclusion is the exceptional rifles with the best matched lots of top quality ammo are consistently around 1/2 MOA at 100 yards for 10 shots in ideal conditions. Even within very high quality rifles and ammo, in fixtures and tunnels, these are...

Assuming 1080fps and 1:16” twist, the bullet is spinning at 48,600rpm at the muzzle. A good test of supersonic vs subsonic accuracy potential might be to shoot both at distances before and after the transition, and look at relative precision. Ideally you would capture velocity at both muzzle...

These are shot off a 6' stepladder, mostly 2 shot per rung and arrow indicates if I was going up or down the ladder. Top of the 1.5 MOA target was starting 1 yard behind ladder, get into position and fire 1 shot within a 10 or 15s par time. Support side means entirely left handed. This really...

I worked my way through the remainder of How do bullets fly? and http://www.varmintal.com/a22lr.htm, as well as a couple links from those sites. I had read Varmint Al's page years ago. I also found the Hornady Ballistics Playlist quite interesting. BowChamp, thanks for the photos and...

I'm working my way through this tonight (and probably for the next couple evenings).

No, he's Canadian but competes internationally, primarily in the US. He occasionally shoots rimfire PRS events with us during the off season.

I'll have to review the links some other time, I can't afford to get sucked down the rabbit hole this late when I have to be at the office tomorrow morning. ToddM, BowChamp, wind is certainly one of my weaknesses. Running a flag (surveyors tape hanging from my CF tripod at mid-range:eek:) was...

If I look at JBell's threads and use a 0.75MOA average for 10 shots and an approximately equivalent 0.60 MOA for 5 shots as a criteria, I get these results: 5x10 Average: 1: 0.770” / 0.735 MOA (jbell- Anschutz Benchmark 10/29/19) 2: 0.770” / 0.735 MOA (Reubenski- Vudoo V-22 4/30/20) v1 6x5...

This is a little bit tangential to the direction I wanted the thread to go (what are shooters doing to produce the smallest 22LR groups consistantly), it is still interesting. This sounds like a published study. Do you have a link?

Thanks for the links to the related threads Justin and JBell. I had forgotten about both of them. My experience with ammo preferences is similar to Justin's but with minor differences. Short version, lot preferences are gun specific. My re-introduction to shooting as an adult was bullseye...

I’m hoping to start a discussion about all aspects of shooting small groups with 22lr, gun, ammo, rest/position, shooter skill, technique, etc. Generally what does it take to generate the group sizes we all aspire to, but with statistically significant sample sizes? I want to improve my own...

Justin, do you have a link to the thread?

Now that I have your attention, how? What does it take to produce 1/2 MOA(ish) groups on demand? Is it even possible with 22LR and if so, with what caveats? There are enough 6x5 averages posted in the 1/2 MOA range that it can't be a statistical anomaly. There are some extremely skilled...

In hindsight, I wish I shot this as singles and built a composite group as it would allow correlation of velocity to POI for each shot. I've been using GRT for group analysis but plan to try OnTarget TDS for the composite group capability. While interesting, further exploration of this ammo at...

Targets from my Biathlon Extreme lot testing. Targets images are rotated 90° CCW (right edge of image was bottom of target).
