My custom BR rig is right bolt, left port, so I understand and appreciate the convenience of loading ammo from the left side. However, when I used my CZ 455 with a single-shot adapter, I inserted rounds over the action but below the scope (between the gap). Worked out fine. Have you tried that...

I think it is more important to know if you are left- or right-eyed. Most people have one that is dominant. If you favor looking through the scope with your right, I find it more comfortable to set up on a right-handed bench and lean to the right. Then, whether you are right- or left-handed, use...

https://www.killoughshootingsports.com/index.php/actions/stiller.html Stiller's actions are in high demand. Expect to wait a while. Shilen Ratchets are popular and often in stock. Dan can sell you the pieces, recommend gunsmiths, etc. Consider a used rig. Albert

Two words used to mean the same thing.

Hi Greg, Although I consider the match costs to be incidental, I still weigh value. To me, the IR50/50 target fee of $1.50 seems to buy little or nothing. In contrast, I recognize the value of the $1/target ARA charges. The fees support a wonderful, easy to use website full of information...

Hi Greg, I wasn't one of those "complaining" about the price, but at first I was a little surprised when I learned what it was. The ARA matches many of us attend cost $15-$20, a price that changes little or nothing whether we shoot four or six cards. One range down south charges even less. So I...

Outstanding experience I very much appreciate how much everyone did to run the 2018 USARB Nationals. and, in particular, I very much appreciate how much individual support I received. I had strong reservations before I signed up. I had never been to an official air rifle match before, although...

.22 scoring plug Here's one made of brass. https://www.killoughshootingsports.com/index.php/scoring-supplies/ara-scoring-plug.html Albert

HV Nationals Can you post the entire list? I didn't get to see it at the event. Thanks. Albert

Range fees? Hi Garrett, Does registration cover range fees? If not, how much are they? Need to know how much money to bring, who and when to pay, etc. Thanks. Albert

Hi Garrett, I just tried registering. Paypal shows I sent payment, but the site blew up on me and I can't get back in. It isn't clear registration details were sent to you. Is there any way to confirm my registration? Thanks. Albert

Orion targets Hi Garrett, What will you be using for targets? I understand Orion won't support 25 m and 50 m targets any longer, and don't plan on selling them once the current supply runs out. Do you have a source for them afterwards and enough for the Nationals? Thanks. Albert

"...scanning provides one key indisputable element: a virgin image of the unaltered hole." Not true, unless you scan targets while they are still on the stands. Pellets do not punch clean holes. As you point out, they tear the paper that pushes out the back, creating punctured dimples. Once you...

Clarification please. Heavy Varmint? Do you mean under 20 ft-lbs? Also, some rifles seem to be labeled .22. Did you use the official target for 50 yards or the one used for 25 m? Thanks. Albert

OnTarget TDS analysis Hi Kim, Here are the analyses of the four data sets. Order is the same as they appear on your target. Unfortunately, I don't know how to post a higher resolution image. The originals look better. Gotta run. I'll add some comments later. Albert

Hi Kim, Actually, the vertical impacts of the rimfire ammo are only weakly correlated to velocity. The correlation coefficient is 0.57. Most of the dispersion must be due to other factors. Also, thanks for posting the raw data. Correlation coefficients for the four sets range from about zero to...

Hi Kim, When shooting high quality (Eley Tenex) rimfire ammo off a stable fixture in a well-controlled indoor facility, velocity dispersion contributes very little to impact distributions. One is lucky to see any correlation with fewer than 100 rounds. Often many hundreds are necessary. (For...

Hi Kim, Unfortunately, a group of 20 probably isn't large enough to calculate results with high enough statistical significance. I'd be curious to see your individual measurements. Thanks for sharing. Albert

Hi Tim, My guess that the answer lies in places no one is looking. Ever since large scale manufacturing was born, their output has shown variation. Processes seem to be running fine for a time and then suddenly and unexpectedly the output is out of control. Process engineers work on the problem...

Got any left? Did anyone propose why that ammo was so much better? It must provide clues why it did so well. I'm guessing no one figured out why, or if they did, weren't able to recreate it. Albert
