Pellet Accuracy Testing - 2011-06-10

I decided to follow up the previous test (2011-05-24/25) with the new elevated shooting rest and concentrated just on the wadcutter pellets I could most likely to purchase from online vendors, as opposed to "discontinued" lines [example RWS Club 10 and CO2 Target].  The intention being to see how accuracy improves/weakens using the new rest.  Clearly, to my eyes, comparing the previous results with this one shows a marked improvement in numbers, and obvious effect the less-than-stable rest I had used previous to obtain results.

* This batch of Crosman Competition Wadcutters came from a new blister pack of 500, not from the last batch in the tin I had used on 2011-05-24/25.

** It appeared both the RWS Basic and R-10 Match had two groups of 5 affected by a CO2 Powerlet running out of gas.  Ironically, or interestingly, the "Best 3" in one of those groups of Basics affected was .370", while the group of 5 measured 1.511".

*** Though I have the power adjuster turned out for "lean", I was not getting a longer string of shots, and had elected after the first two targets  (40 shots) to change CO2 and stayed with that format, even though I seemed to run out of gas on the noted RWS Basic and R-10 Match WC targets.  Paper tearing and wider groups were evident on them, but not on others at the end of the 40-shot string.  No Powerlet was weighed, simply plucked from the box and used.  Shooting in the basement @ 70 degrees does seem to make a difference on shot count.

**** The "Best of 3" determination is what I term "The Ayoob Rule".  Well known gun writer Massad Ayoob came up with a way to determine ammunitions group size and eliminate the "human error" factor - as opposed to using a mechanical rest such as the "Ransom Rest" by taking a 5-shot group and measuring the best three (closest) shots, dropping the two others, thus a function way to rule out possible human error influence or even the well known "4+1" auto pistol syndrome where a semi-automatic pistol will shoot one shot off from the rest of a normally tight group.  He and Charles E. Petty [using the Ransom Rest] even ran a "dueling" pair of articles in "GUNS Magazine" on the comparison of such a systematic approach.


This shows them ranked in order of group size, smallest to largest.

How Interestring! The top four pellets, the same order in both catagories, are the same!!

Honestly, I am not sure how to interpret your figures. I believe that certain pellets work better in specific guns and for specific shooters. That point you backed up by having four types of pellets provide you a good group of shots with the same gun. Your work is about done. The rest of us must shoot many types of pellets (sorry about our wallets) to find pellets that work best for us.

I am most bothered by fliers and inconsistant pellets that totally foul up a shooting session. It would be excellent to find a few manufacturers who provide consistantly consistant pellets.
