Others 30 shot groups @ 50y

[FL22]

So a little backstory first, because I’m sure some have questions.

I don’t know if any of you have ever just set a target and just continue to shoot a paper target repetitively in the same place just to see what happens to the group size.

How long can I keep it under a dime, nickel and quarter. How big will the group get?

I do that all the time just for fun, usually after an unwanted flyer then I gotta keep it under a nickel and so forth.

So we have this thread I’ll post a link, where one of our members posted a video from a pb ammo manufacturer that to me were challenging the current accepted shot counts (3,5,10) for more accurately expressing MOA group size of a given set up: rifle, ammo and shooter.

Three Shot Groups for me Going Forward…

Anyone watch this Hornady podcast?

community.hardairmagazine.com

Starting this thread with my S510 .22 tested today pics next post.

 

[FL22]

Five shots each 50 yards JSB 18.13

30 and same 5

 

[FL22]

5 each JSB M-lights

30 and same 5

 

[FL22]

5 and 30 same POA, I was starting to feel a little fatigue. This was the last target I shot I did hand pump the rifle back up to the same 200 bar for the beginning of every target.

Covered with a dime, 5 shots

 

[FL22]

So my thoughts are that I need to do another set of 30 with the 18.13s if they are just as close, I’m not using the M-lights anymore and saving money.

Prior to this I 100% believed that the M-lights were what it shot best.

I think shooting 30 shot group gives up to much environmental error (wind). Here is how i grade my guns. 5 groups of 5 shots done fairly fast for each 5. Then you can measure each group size and get an average. Now you have lots of data and maybe a little less variability.

@FL22, a very informative and interesting endeavor on your part, thank you… Quite the difference in a 5 vs. 30 shot group. For the way I shoot, though counterintuitive, the smaller groups are more statistically significant because for my airgun useage? I am never sending 30 rounds at “any” particular target… One to three rounds while plinking and move along. On critters? It a DRT hit or miss, second opportunities on the “same” critter? Rare…

I'm on the same page. Pushed my S510 from 20 to 80 Yards this summer (posted it somewhere on Ham!?)with Mrds vs M-lights, vs 18.13 Jsbs. M-lights were supposed to be the shoo-in. Nope. Mrds were tight (minis the crazy drop) and the 18.13 held there own fine to 80Y. I will try this with my PCPs, i do this often with my 2 .177 springers. That turkey challenge @50Y with the Ghost opened my eyes to this a bit more....I'll probably stick with 20 shots per gun though, I too hand pump...Will NOT be buying anymore M-lights....Ghost hates em as well.

If you used a fixed bull that did not tare away or in large that draws your eye off you may shot more consistently tighter having a dedicated fixed aim point that remanes the same through out.

Good point bud, to overcome this I used the minimum magnification on the scope also the target I used aids the shooter in holding a fixed POA.

You can learn a lot with larger group sizes. I am spoiled with having electronic target systems here at Crosman. I can shoot 10-shot groups for electronic record and keep shooting through the same hole in paper to see the consistency over a large number of shots.

The main thing you learn is the "flyer" in your 3, 5 or 10 shot group, stays within the larger group.

I've also drawn a crosshair on the target, so as the bull disappears I can keep it on point!

I just consistently miss the bull so it's always there to keep aiming at.

Hey, that's my excuse, too!

 

[Florida_Man]

I started my own test indoor 10m with my S200

I got the 3 and 5 round groups in

Big savings on targets

 

[FL22]

So I got some interesting data today. Confirmed at least one suspicion I had about my S510.

Please review the 5 and 30 shot group in post #2

Now look at this from today.


So I’m thinking to myself what’s going on here?
Everything should be the same roughly, but that’s a big difference.

I decided to do this.


The results after cleaning:

Back to the same 30 shot 2.25 MOA.

I started this test with the rifle cleaned. I clean every 200 as per the owner’s manual.

I’m going go less than 100 (80-90) and clean from now on if the M-light group also improves in the next set and I will start with a clean barrel for that 5 and 30 group to be more consistent.

Perhaps get an RV and try the snowbird lifestyle .

We have a big chill coming our way. I grew up in the cold north, but it doesn’t take long to become a lizard person. Going from 80 during the day to 40’s at night is a shock to the system.
