Chrono is 4 oz, plus 4 oz steel, used electrical tape to protect barrel, = 8 oz more at the muzzle, has a good feel, only seeing heartbeat movement now. Think this is a good place to stop, and just under the 5.5 kg=12.1 pounds ISSF limit.

First shot being off is likely air creeping past the regulator. The first couple shots resets the pressure in the plenum.
I have an FX Crown GRS Continuum myself, but my only offhand experience was a few shots during a field target match. I wouldn’t know how to answer any of your questions and it seems you’re well ahead of anyone else’s learning curve by now.

It is a known problem for right handed shooters to pull shots down and to the left because of intrinsic muscles involved during trigger pull. I am assuming your right handed.

Am thinking of a wireless tablet/phone camera located at the target, talking to a to a laptop , possible monitor/tv screen, to watch the shots at the target.
Have done this indoors at 10 meters. Just wondering how far wireless will go distance wise, 50 yd, 100 yd 200 yd?.

Tonight's
2nd target, holding tight until the end I got tired and lost a couple. Had switched from 27 g to 25.4 gr knockout. Went from 840 fps to 860 fps. Getting comfortable controlling the muzzle at discharge and follow thru. Maybe 4 clicks left.

First shot having deviant POI is likely reg creep. Check it with the chronograph. Shooting high implies that your hammer strength is suboptimal for the set pressure. Setting a HST closer to the max possible speed for the reg pressure will minimize the effect of the creep.

Still needing the first target to warm up on. The second target always feels better. Funny part is , at the end of the second target I get burned out, throw the last 2 shots wide. Guessing my answer is to keep working at it. Total time for both is 1 hour to 1 hour 15 minutes.

Got my first chance to shoot in the rain with AR , already had the targets set up and was starting first shots. Then the heavy rain started, hung in there and finished, it was fun, something different. I do have a metal roof overhead of firing position. The rain did not seem to affect
the shots.

Removed the 700 mm barrel (110 Bar,neutral cam wheel pos 13, 25.4gr, 850 fps), installed the 380 mm barrel ( 130 Bar, neutral cam wheel pos 20, 25.4 gr, 760 fps), the 380 has much less recoil with these parameters.

Am sticking with the 380 mm barrel, it has much less recoil than the 700 mm. Faithfully practicing every evening, with good results being seen.
One item to address is the occasional infrequent flyer shot, More often at the beginning, and this has been reduced by a few slugs shot as warm up shots.
However last nights 4th record shot was a 7, and the 18th shot was a 6, this was not me, as I have become very good at seeing and calling the shot.
Searching the youtubes and here, and seeing the silicone grease useage, and the hammer spring shuttle situation.
Need to get the chronograph back on, but removed it as it was so darn consistent. So if my fps is consistent, questioning, where the issue is, all I am thinking is Pellet variation...? Or blame myself...? 755 fps to 764 fps range with 25.4 slug, 130 bar, Will try some HN 27 grain slugs.

maybe temporary to play with the weight would be lead wire (plumber solder ,about a 1/4 inch dia. ) so you cam move weight closer or farther on the barrel ??

Cleaned and lightly ptfe greased the Hammer spring, and hammer spring shuttle, also silicon greased a slug and cycled it with 10 shots.
These procedures brought it from 764 fps max to a 780 fps max. More shots needed to see if it settles down a bit.

Since the beginning, Have always had an infrequent flyer shot, and finally took the barrel shroud off, the spacer380/spacers700 were not in the correct location. The 700 all 3 were stuck together in the middle of barrel, the 380 single spacer never made it past the end threads, so barrel was completely unsupported. Fixed the situation, and benched it, and very glad to say, no more flyers. My sons target at bench, the 2 eights were his learning the light trigger.
This spacer situation may also explain my shot group variation between Bench and Standing, which I could count on being 7 inches difference. Sighted it in for Standing(difficult), and when I bench rested it, the group would be in the 5 and 6 ring at 3 o'clock.
Out of curiosity, does anyone have any experience shooting unshrouded, unsupported barrels and how they behave?
So if anyone is having , any way out flyer shots, please check your spacers. Th
is all makes perfect sense as the chrono #'s were all very good.

Learned from a thread here, "weird crown shots". that my wild shots maybe from low velocity , velocity , rotation rpm ratio.
So now am at 140 Bar, 930 fps, 25.4 jsb slug. 700 mm barrel stx superlight 24:1 twist, yes it is pellet barrel, and will get some jsb 25 pellets soon.
So am at high setting for hammer spring internal adjust. Position 18 for rainbow spot.
150 bar does 955 fps at 21 , 22 wheel position.
Am doing Standing , so any better than 1 moa works well for me.
So do to this higher hammer spring setting for the higher pressures, my light stock trigger setting for 110 bar and 130 bar could not hold the sear. Perfect time for the Boss trigger kit install
and very pleased with the results. The Boss trigger is still light and holds well at higher bar pressure 140, and 150 bar.
Dremel work is fun!

A few recent changes, includes indexing the 700 stx 24:1 twist barrel, Jsb 24.5 slug, 140 bar, 980 fps, Boss trigger install.
Am not seeing anymore wild flyers that I can complain about.
HN 21 and HN 23 slugs, JSB 25.4 mrd pellets, coming today, so will see what the 24:1 twist barrel will do with the proper lead.
Very possible order for stx 700 heavy 18:1, if choosing to shoot HN 27 slug.
As of now, very good feel for calling every Standing and bench shot, not any weird ones happening. If I can get a tighter group in the future , all the better!
One pic is Bench after indexing barrel, sight move was 40 up, then 8 down
, one pic is last nights Standing.
Will take some time to get used to the Boss trigger, but very pleased with the install swap.

Needed to get a sense of reality again, so pulled back to 50 yards for good grouping check, Standing position with JSB MRD 25.4. Proving no flyers at 50yards. Some times shooting is surprising.5 shots per bull.
More trials to come with hn 21 and 23 slugs, most likely a 700 18:1 twist barrel coming for the heavier slugs, 27 grain.
