Wow Steve, great shooting, terrific set up, and gorgeous rifle. I also like the early morning or late evening.
The wind really plays with my mind. I went out last evening at 8:15 and shot a 1.187 CTC group. One pellet  had a mind all its own. I know it wasn't me ;D,

 Congratulations on your success. Once you reach this level it is oh so hard to shrink those groups, everything must come together and also a bit of luck, at least for me.

I shot this group on 6-5-17 with my FX Boss.  Shot it benchrested and bag to the rear so the rifle is held to my shoulder.  Scored a 50 and a CTC group of 1.247".  Was hoping to qualify for master in NUAH, but will have to keep trying  ;)   Made a video of when I was shooting and it is posted here. 

Scan of the target and picture of measurement are below


Very nice target Tim, way to go ;D

Nice target Steve! The things we do for ideal shooting conditions.  ;)

Thanks Tim!  Yep, not much we won't do to hit the range during ideal conditions....and it doesn't happen that often that's for sure ;D


Great target Steve. We're getting some really good scores this match.

You have everything you need to get into the NUAH Club. Just copy and paste the info in a thread over in the Long Range Club gate and I'll add you to the list. Looks like you qualify as an Expert. Congrats.

Thanks Marty ;)

Thanks mr007s!  Early morning and evening are the prime shooting times for sure.  Lately It is windy almost all the time around here, but this morning things really came together.  1.187" ctc.....OUTSTANDING!!

Guys. don't be afraid to post your target if it's not 50/50.... My first target last month was only 41/50.... but I'm still proud of being able to shoot that with an airgun at 100 yards.... Just think of where airguns were a decade ago !!!

I agree Bob!! In comparison to centerfire rifles, we're sending a mere spec of lead down range. At 100 yards it doesn't take much for things to go awry :o

My printer is currently on the blink.   :(
Been shooting at my new metallic targets.  It is fun to squeeze the trigger, hear the pellet whiz through the air for nearly half a second, then that satisfying metallic "PLINK!" down range and the target falls over.   ;D

I got a chance to take out my Hatsan AT-44 S10 Long today, tuned to shoot the 34.2 gr. JSB Heavies at 960 fps (70 FPE).... I spent quite a bit of time dialing in the Air Stripper, and I can now tell you that they certainly do affect the group size, changing it from 3" down to about 1.5"

Bob

Nice shooting. I wonder if the air stripper adjustment changed how effectively the air was stripped away or was it more to do with harmonic tuning?
Also from my crude calculations (for higher velocity bullets) at 960fps with a 17.5 twist rate barrel the 0.345" long pellet was a little over stabilised. Have you considered testing accuracy at a  lower velocity out of curiosity?
Ted Bier won the 2016 EBR shooting the same pellet at 830fps but that was in an FX barrel and I don't know it's twist rate.

The argument about whether Air Strippers work by stripping air (minimizing turbulence) or changing the harmonic tuning will never end.... I don't know which is occurring, all I know is that they clearly make a big difference in group size, with quite small adjustments.... Interestingly, every one I have tried seems to work well with a gap of around 1.5 calibers, which leads me to believe they are working by stripping air.... If they were working on harmonics, a slight change in velocity should throw them out of tune....

This is primarily a hunting rifle, for taking Marmot sized animals (up to 10lbs.) out to about 100 yards.... Accuracy is important, but so is power.... so when I achieved what I considered adequate accuracy at the velocity I had, I didn't worry about whether it could be improved by dropping the velocity down.... If the FX barrel Ted was using at the EBR was a Smooth Twist, you can bet the effective twist rate was VERY SLOW.... I have seen measured rotation rates of pellets from smooth twist barrels as slow as 1 turn in 13 FEET (156").... The pellet strips as it goes through the rifled portion, and only picks up a portion of the designed in twist.... I happen to believe that our Diabolo pellets get so much of their stability from drag (shape) that they don't need to spin very fast.... In fact, I have never seen a pellet hit in yaw (ie starting to tumble) because it wasn't spinning fast enough.... but I have seen lots that spiral if they are driven too fast in a barrel with too fast a twist for that pellet.... This is called Dynamic Instability, and there are two cures.... Use a slower twist rate.... or drop the muzzle velocity.... The cause is the pellet slowing in forward motion while not slowing to the same degree in RPM.... I saw no evidence of spiralling in the Hatsan, so didn't think it was necessary to slow it down....

Finally a day with no noticeable wind. Our range doesn't open until 11:00am and usually the wind has picked up by then.
The target below was the first of 10 I shot. The 16X Leapers scope I was using has very clear glass but the turrets are unreliable. On the second target I clicked the windage 1 to the right expecting a 1/4" move but instead the first shot was again to the left and the next 4 in a tight group over an 1" to the right. I managed more 1.25" groups but never over the bull's-eye again.

Ed... nice shooting.

If the pellet using a gauge or you best guesstimation isn't breaking the line on the bull it would qualify as an X.

My .30 cal entry. I had to run an errand today and it was close to the range so I bought along an airgun and had another chance to shoot this match.

I also added a target from the last time at the range I was saving in case I couldn't make it back before the end of the match. The score wasn't that good but it sure was a nice group ;D

Thanks Marty, nice shooting yourself.
Next time I'll use better paper or backing to get clearer hole borders. I examined the target under high magnification but with the center blown out it is a guestimation. Personally I believe it is 3Xs but I plan on entering match #3 and so on so time will tell what the gun can shoot.
