Do you find any benefit in using the card stock shim? Or was it more to keep the barrel from getting marred up? Again... Nice Shooting!Yes, I had it taper bored about 10-15 thousandths oversize, to accommodate some card stock shim. I don't like clamping directly on the barrel.
Keeps the barrel from getting marred up for sure, but mainly I just like having something a little "grippy/squishy" in between there to keep things solid. I also don't want the exposed aluminum in the tuner doing anything "stupid" because of being in direct contact with dissimilar metals or cerakote.Do you find any benefit in using the card stock shim?

I hope everyone realizes that this is the best 6X5 target that has ever been submitted, not only the smallest average but the smallest single group. Well done Greg!I finally had a decent condition. One of the first times this spring I've had the wind this steady. Wind was barely tugging 2-5mph, but had a nice steady wide pace to the changes in intensity... and I cranked off 6 good groups with one absolute stunner. Might be the smallest group I've shot to date with a rimfire. Best news... I shot it on camera. This tuner has pulled a solid tenth of an inch out of my group size, on average.
Distance - 50yds
Ammo - RWS R50
6x5 with an average of 0.128".
Here's the rifle:

I agree, there is no way to tell that fine of resolution when measuring something that isn’t hard so your calipers stop on it.Woohoo! Very cool to have the best target to date!
In fairness to @padom, I didn't see the standings on best group until I saw your post @jbell... and when it comes down to measuring what amounts to a single bullet hole, and trying to hold thousandths with a caliper... I'd say he and I are tied on best group. My measurement might be a thousandth better... but there's no way in hell I can hold that kind of tolerance with a caliper and my eyeball on a flat surface with no holds for the caliper to grab onto. I had to measure that friggin bullet hole a dozen times six different ways to come up with the .009". I'd measure it once and get .010, measure it again and get .006... It's just really hard to get that small. The only proper way to do it would be to have a scanner and an automatic measuring system of some kind and have everyone's target measured on that.
That is some fine shooting and a fine rifle. What's a set up like it cost, $10,000? Having never seen that particular scope brand so I had my friend google check. I'd have to sell all four of my 52's to buy one. LOLSure, here's the rifle specs
Rifle built by TS Customs -
Tangent Theta 525P Gen2XR optic
Hawkins Heavy Tactical rings
Triggertech Diamond pro-curve trigger
26" Benchmark 3-groove 16.5 twist MTU contour
22LR Primal 2° chamber
McMillan A5A McWoody stock
Hawkins bottom metal
Atlas PSR bipod
Yeah, $10,000 would get it done. We sell everything in the package. The rifle itself is about $4500, the optic I'd sell for $4500, Hawkins rings $200, tuner is around $200, ARCA and picatinny Mlok adapters $50-ish each, Atlas PSR bipod $320, extra magazine $130... puts you right at $9,950... and it would still need to be shipped to your FFL.That is some fine shooting and a fine rifle.

Yeah, I shot the group on the left after I was done with the 6x5. Then I went inside and was on the phone for a bit... came back out and the wind was gusting hard and made that embarrassing group on the right.EDIT.
I see in the video you shot up top in the middle as your first group. I wasnt following looking at the target.
SOP is to skim-bed the tuner, using release agent, then torquing to 5 inch/pounds. Card stock is interesting. A material with some inherent Damping, more so.Do you find any benefit in using the card stock shim? Or was it more to keep the barrel from getting marred up? Again... Nice Shooting!
I own the Atlas PSR and Harris both with Area419 Arca adapters and the MDT Cyke. For purely shooting groups, I find the most stable setup using the Harris with spiked feetBipod question. For the guys who shoot Vudoo's, can you recommend the best bipod to shoot from with a Vudoo?
Or various F-Tr setups if “legal”I own the Atlas PSR and Harris both with Area419 Arca adapters and the MDT Cyke. For purely shooting groups, I find the most stable setup using the Harris with spiked feet
Shooting steel from different positions I prefer the MDT then the Atlas...
L:First time trying at 200 for groups.
Vudoo V22 18" Kukri
SK Pistol Match Special
Prone, Bipod, Rear Bag
Average Size = 2.476, MOA = 1.18
Best Group = 1.57"
My dope is a bit all over the place. First group is actually the 2nd one from the upper left. I dialed 6.5mil based on the Ballistics App, and it shot .5mil low, My last 5 groups were at 6.9mil. Last time I was out here I launched 10 rounds spot on the target at 6.4mil, it was a warmer day and the app had me at 6.4mil. Spot on. Today it had been raining, but the rain was stopped. It was just cold and dreary. I got the weather from the kestrel, and it adjusted me to 6.5mil. No wind that I could tell. Chrono showed consistent muzzle velocity at 1114 average.
