Q:

.30 STD. 245 bar to off the reg. 30 shots now !!

Here is my first string from my .30 Std. for comparison. I just got my chrony figured out this evening.

Reading down through and studying my #’s I think after some comments hopefully, am going to need to bring my reg. down a bit and see if it smooths out. I think less Regulator and more probably more HST will be needed to flatten the string. That’s from “0” experience other than reading this forum to learn, but either way I’ll turn it into practical application and find out if I’m right or not. unless otherwise advised. I am lost as to explaining the dip on #7 – #11 so i’m all ears on that. Also I was estimating that #26 bar reading since I shot to #28 and it was 115 when I looked. They drop like a rock when they fall off the reg. My gun has about 800 rds. thru. it so far. I am going to be filling to 230 bar and test at 240 while watching air consumption. I really want 27-28 shots, 25 clean and 2-3 sighters if I can figure it out the combination to do it, but a smooth string and best accuracy will dominate my criteria for adjusting things.

You’ve got 22 flat hot hunting shots for the Standard. It appears that the velocity can go up a bit more by lowering the Reg. 😯 So I guess now you need to lower the HST a bit if you want a few more shots? Maybe try 1/8 turn or 1/4 at most.

I tuned the Reg back down to stock and backed out 1/8 turn from there. It measured .1915 from the adjuster hex head to the top of the body with the jam nut removed. This is getting closer. I am gonna shoot another couple of strings to let is settle down and then go from there. I was low on air again trying to bring it up from 0 with a guppy and 225 was all it had. I’mm filling to 24 and have another go.

Yea I don’t understand that design. To add a slot is nothing.

quote synopsys:

I slotted mine even before adjusting it. 😯

I just didn’t have the heart to fuck it up with a pair of pliers.

Gotta say Ed should have refined the HST adjuster long ago really… Sad that most people have chewed the shit out of their $2000 rifles with pliers. Same thing with the trigger rod. 👿

Thanks synops…..got it now.. I turned mine up instead of down !! String kinda looked like it but could not be pos. until now,….headed to bed…..

Here is my HST adjuster I had bought last spring I think with the slot in the end. Worked out great for the 30 cal.

The adjustment regulator screw has normal threads.

The regulator CAP screw is reverse thread.

😉

But some are backwards…

For the normal threaded adjustment screws:
Turning the adjustment screw clockwise (in) turns the reg pressure down, counter clockwise (out) turns the reg pressure up.

For the reverse threaded adjustment screws:
Turning the adjustment screw counter clockwise (in) turns the reg pressure down, clockwise (out) turns the reg pressure up.

The one thing that holds true is if the adjustment screw is screwed towards the reg the reg pressure will go down.

One of the better ways to tell the adjustment (instead of counting portions of turns) is to measure from the top of the screw to the shoulder of the hole.

Been looking at this last string and my end of string swell got higher, thinking about it I turned the reg the wrong way considering the left hand thread I am pretty sure. I just saw this talked about yesterday but can’t find it, must be getting tired. Another round tomorrow. Gained maybe 10-12 fps with an 1/8 turn up ?? sound logical ??

I have a couple HST adjusters coming in the morning too, friend in New Orleans made for me. He adds some little spanner holes in the tip end so you can use a punch to turn and more threads to get lower than the oem allows.

Well I got mine back together, I cut an o-ring on the first try but found the sliver before finishing the job, swapped it out and and I did not realize how much air I would consume doing the tear down and re-assembly. I did not realize I would struggle airing up from “0” with out it being cocked to get the hammer off the valve but I heard air coming out the BBl. and it dawned on me. Duh. I only got a 200 bar fill and was working the HST back up from 830 to 845 to 865 to 880 to 886 and then the spike showed up again and I jumped to 910 ish. so I need to back off my reg. some more. I am going to re-fill and see what the peak FPS is via. HST and then go from there. By not doing this before backing that 1/8 turn off on the reg. I am lost until I can get 2 data points to work from. Any advice out there ?? Sitting around compressing air……

TIP : Don’t do this upon re-assembly !!!…. old pros !! Have any of you ever rolled the knife edge where this occurs just slightly to make this easier to avoid ?? or just be careful and don’t do it again !!

I am just going to raise the HST to get it around 870 and see how flat the string is. I have that Black HST adjuster someone made to replace the stock one that is tough to grab.

Mine was not tight at this joint so there is another question I guess. The joint just left of the pen tip was looser than hand tight ?? I just run it together with lite pressure. Going to back off the reg. 1/8 turn and the HST 2 turns and work up to see what I get for a peak. Whishing I would of raised the HST before taking apart so I could see what 1/8 turn nets in change. Oh Well.

Going to need lights to finish BBQing. 🙂 Looks like it is set between the 130 and 160? Ed’s video said he had them set to about 150. I guess the slot lines up about with where 150 might be? Who knows?

Here is my reg. out of the gun and has writing on it, 160 and 130 I’d like to understand this before I change it ?? I don’t imagine that will happen though.

It is seeming so to me yes at times, I mentioned it earlier, or ask a buddy on the phone I can’t remember which but I will say also !! that at times the flyers/wierd #’s don’t come as a result of timing either, just outta no where. I will be shooting on a timer when I come back, tearing mine down now.

A valid point right there ! :thumb:
