Didn't try it with the hammer spring set flush but I would expect not much change.
Really didn't change much with hammer spring adjustments with reg at 90bar.
I'm gonna up the reg a little now.

Well guys, add the 20gr Griffin slugs to the list of slugs this baby can shoot!

Thanks but my guns are fine with the stock springs backed way off. What I do need is something I don’t know if I can buy. I picked up a corrosion special Uragan. Reg was corroded so I used the stock one out of another Uragan. The barrel is corroded and now pitted out near the end. I could chop it but I already have a compact Uragan .22. So I figured since I probably can’t get a new one I’ll just have find a random barrel and machine it to fit. Couldn’t pass up the gun. Got it for $300. I don’t know how you are communicating with them but see if they will sell a new 600mm .22.

Nice!!! Gotta shoot through those 10gr faster I guess
they are really nice and shot a few sub-dime size groups at 70 yards earlier when there was a window with Alamo’s now wind, 1-2mph constant breeze, easy to hold for. Then it went wonky again and those things get blown around quite a bit… the good thing is the hits stay together, they just move by a bunch depending on wind Upvote 0
I got you. I put in the order for the other stuff, but I asked them how much it would cost.
I'm communicating with them through their support email actually.

That's awesome. The gun is shooting so good right now. I don't wanna mess with the current tune hahaha. I really should use these five or six tins of ten gr slugs, but it's likely improbable now haha.Nice!!! Gotta shoot through those 10gr faster I guess

Shoot through your 16 grain, then define for the 10gr and when they are done open up with 20gr

The 16.5gr tune is working with the 20gr lolShoot through your 16 grain, then define for the 10gr and when they are done open up with 20gr

Buuuuut is it the optimum for the 20gr?!?!? You’ll never know unless you try JK, I wouldn’t touch it if it shoots both like that

I’m up to 940 now with the 10 grn. Gotta shoot it, see if better.
949 fps average with ES of 7 - a couple of 8 shot strings over the chrony

Mine are at 975ish right now and very accurate at that speed so I’d think 950 will work fine as well!

I'll take a 7 shots submoa group at 100yds with winds in .177 any day lolBuuuuut is it the optimum for the 20gr?!?!? You’ll never know unless you try

Things have gotten better but these small light slugs sure do get pushed around by the wind.
944 average FPS - 1st pic has at least 2 full magazines
Uragan 2 600mm .177
JSB knockout slug 10.03 grn
42 yards

Looks like you're getting some heavy wind given how nice they group in the center.
So the 20gr and 16gr Griffins are working best at the moment for long range! I managed a 3-3.5" group with the 20gr at 211yds and a half moa group at 211yd with the 16gr!
16gr 990fps avg 35 fpe
20gr 917fps avg 37 fpe
Still getting over 70 shots per fill!

Nice!! Wish I had easy access to to a place to shoot beyond 100y. Backyard maximum is around 120y and that’s already pushing it in terms of shooting at a weird angle through a bunch of trees
