That’s impressive. I really need to try one of those.
My T1X is pretty great out to 200 yards, same as my mostly Kidd 10/22. But 2moa is pretty damn difficult at 300 for me, mostly vertical. My range is well lined with trees on the 300 yard line and wind plays a factor but not as much as it does for many.

I probably should have qualified that I did not precisely measure those shots. The target was a full size IPSC steel that was freshly painted. The glass on that gun is a Cronus, and the hits were clear as day.
I have no regrets with the bergara. I was initially going to swap it into an MPA chassis, but opted to keep it in the factory stock. It really is nice.

500 yards, 24" square plate.
I've never actually measured groups, I just get a kick out of hearing the "ting" 2 seconds after pulling the trigger. You can run the bolt and still have to wait for the impact.
It's accurate enough I beat a Vudoo and rim-x Saturday. Not the gun, but it's close enough that the shooter is the one making the difference.

Sk long range match or pistol match special. Special shoots much better than standard pistol match for me.
Pistol Match Special and Long Range Match are both 1106 FPS ammo, Pistol Match is 1073 FPS ammo, same as Rifle Match and Standard Plus...from what I understand.
All the pistol ammo is way off advertised out of a rifle barrel so I haven't ever really payed attention I guess.
I just zero at 50, get drop at 200, and true the velocity in strelok. Verify drop at 250, 300, 400, 500, and call it a day.
A friend put it through the chronograph, he compared the ones I listed. The 1073 and 1106 FPS numbers are what SK lists. He said he was getting ~1090-1110FPS for long range match and pistol match special. There are two velocities manufactured by SK, at least that's the way it used to be, not sure what the semi-auto and HV muzzle velocities are, he never tried them. I'll put rifle match and pistol match over my Magnetospeed V3 when my Vudoo shows up.
This morning, I happened to run chrono tests on CCI Standard Velocity, SK Rifle Match and SK Long Range match out of my carbon fiber barrelled Bergara B-14R . I ran 3-5 ten-round tests of each while I shot 50 rounds at a 200-yard paper target. The weather was sunny, 82-degrees, 84% humidity (considered a dry day in Florida), 1-2 mph wind from 30-degrees to my right front, and 328 foot elevation above MSL. All runs were consecutive other than time to reload the mags. I used a Shooting Chrony Beta Master at about 3 yards from the muzzle.
The CCI SV averaged 1058 fps, the SK Rifle Match 1075 fps and the SK Long Range Match 1131 fps. FWIW, the 50 rounds of CCI SV formed a 9.8 high x 7.5 wide group, the SK RM a 6.0 high x 5.0 wide group and the SK Long Range Match a 4.9 x 4.0 wide group. All measurements in inches. For reference, Eley Tenex printed a 3.5 high by 4.5 wide inch group on a different day with a 6-8 mph wind and a 1142 fps chrono reading.

1131 for long range match...that's pretty "hot". Were you getting any "cracks" from it breaking the sound barrier? According to the site I use, limited to temperate only for the calculation, it predicts 1140.65 FPS for the speed of sound @ 82º F. Not sure how accurate that "calculation" is, since it doesn't let me put in any other barometric details.
ETA: https://www.weather.gov/epz/wxcalc_speedofsound
ETAx2: Sound travels faster in water than air; does that make it travel faster in higher humidity than low humidity? In my head, yes...but I have no idea if that's true.

All I can report is what the chrono read. The highest of 30 readings recorded was 1150 fps with the lowest being 1114 fps. This is out of a two-month old B-14R with 1750 rounds down the pipe. That should be a pretty tight barrel.
I can't testify about any sonic cracking because I double plug with electronic muffs due to tinnitus in my left ear. If there were any, I didn't notice them.
The Strelok app predicted a setting of 22.66 MOA (6.6 MRAD) up with the 1131 fps velocity and the SK published BC of 0.172 and a 50 yard zero for my rig. In actuality, I used 20.00 MOA (5.7 MRAD) up to produce about a 50/50 split of rounds above and below the midpoint by visual inspection. I based this on four 5-shot groups I shot ahead of time to verify the 200-yard POI.

SK Long Range Match is factory rated for 1099 fps (335 m/s). Of course individual rounds will vary in MV and by barrel, but 1131 fps is not an excessively "hot" MV for the round. In warmer temperatures average MV's will be higher than in cooler ones.
1099 fps out of a 26" barrel. I don't know anyone that has a 26" .22LR barrel. I have a bunch of rifles with 16-20" barrels...lever actions, semi-autos, bolts, and a pump. I have a chronograph, but haven't used it yet...so I can't speak one way or the other.
Just before heading to NRL22 Championship late May. Bergara carbon B14R.
Fired 10 and lost the first two due to elevation being slightly off. Wind was 4-8mph 3/4 value. The way low one was shot #4. Not sure what happened there. Fate I guess.
The rest were there by my hand with my aim being near that impact my pointer finger is pointing at. I should have painted an aiming point or water line but was in a hurry.
I've shot out that far before at matches but for the most part I don't have the ammo to waste shooting beyond 300yds.
Not saying its super great...its the only documented group beyond 200yds I got. Probably 10" if you don't include the super low one.
The two really long range stages at the Championship I got 9/10 and 8/10 impacts.
Including two hits on the 350yd 50% IPSC's. Missed a 306yd once. This was day 1....first stage of the entire match. Was pretty stoked.
The last stage of Day 1, I missed one shot on both close targets being dumb and killed the rest including the back 267yd and 302yd.
I shoot cheaper SK ammo compared to most people.

If it's a nominal 1099 out of a 26 inch barrel, it will usually be a little faster in shorter barrels.
The 26" (and longer) barrels are not unusual. For match ammo consumers, especially outside of North America, they are very common. They are used by virtually all 3P position shooters (prone, standing, kneeling). For example, all except one of the Anschutz 54 Match rifles (i.e. not sporters) have barrels that are at least 26 inches long.
Sounds like an ammo issue, not a rifle issue. I'm guessing your T1x will be on par with the B14r in terms of accuracy with the right ammo.
Personally, 560y on 24" plate. 7 for 10 shots. Wolf Match Target Extra. (took 3 to get wind and walk them in.)
As a MD, I regularly have a 12" plate at 438y at my matches. Once initial wind call is confirmed, most everyone get 50%. The guys who are shooting B14R's or Vudoo's generally get 7 to 9 out of 10 rounds to connect. Most are shooting, either, Eley Club, lapua Center-X or Wolf Match Target Extra.

Yes, but not for the reasons you state. Humidity changes the ratio of specific heats of the gas, but the effect is very minor, only about 5 fps between 25% and 95% humidity.
Temperature is the real driver of changes in speed of sound. Oddly enough, pressure doesn't change it.
I have shot steel out to 500yds. Once dialed in I can, hit 60 to 70% at 400 to 500yds on 12" steel. If the wind stays the same. From 250 to 330yds I can hit 3" to 5" targets about the same %. My Bergara, and Tikka T1x will run sub Moa 5 shot groups out to 200 yds. (regularly in good wind conditions, better in very good conditions) With Wolf Target and Extra, SK Std +, land range, Biathion, and Eley Club.
When shooting 200yds. and beyond, you are only zeroed for a few seconds, then it will change due to wind. I shoot paper at 50 yds and steel past that.
I have not had a chance to try upper grade ammo, don't know if I need to.
The Bergara will shoot!

Shot my buddies the other day. He cleaned it and let my put some foulers through it at roughly 47yds. First 2 groups were sub .5 then he shot a 5 shot at .180 and i shot 5 shots at .200.
Watched him hit 6-7 shots out of 10 at a 10” gong at 450 and i shot a cowbell at 100 and couldn’t believe the accuracy from a factory gun. Makes me wish I didn’t spend the money on vudoos.
