    I realized the regulator pressure was at 145ish on both veterans because I chrony them and the speed on both of them began to fall at that pressure….

    I filled them up to 245bar and i got 32 regulated shots at 900-905fps. I also did some accuracy tests and the MK2’s performed better than the MK1’s in both rifles.

    every time you take off the bottle, oring suffers, its better to have some spares!

    you can also decrease reg pressure and tune it for 25.4gr…. two friends of mine bought veteran long and both of them came with the reg 145ish…. older models i remember reg came at 125 straight from the factory

    veteran long is not designed for 25.4 grainers, its designed for 34gr king heavies mk2 @890-910fps…. you can decrease power by adjusting hammer spring but consistency will go away because of the de unbalance between reg pressure and hammer spring tension

    check battery power, all 3 breech orings and clean barrel

    check the shroud/suppressor baffles, maybe on that double load it clipped some baffles, test it without shrouds!

    It would be very good to start watching videos that show technical aspects of the rifle such as disassembly for preventive maintenance and repairs, since it is a rifle about which there is not much information, congrats for all your content, thank you for your time!

    check if the barrell and shroud are centered, a friend of mine have one and that was the problem.

    Best platform FX has ever made, the only one I own, or ever will own. 

    agree 100000%.

    maybe the barrel thread is not aligned with the barrell at all

    when we enter to the high end rifles range, I think that what influences the most is a good configuration of the rifle (HST, REG. PRESSURE, GOOD AMMO, A GOOD SUPPRESSOR) since the brands use very good barrels and very good regulators, these last two contribute a lot to precision but you cannot forget a good quality ammo, a good trigger, a well mounted scope and of course a good shooter

    it´s better to bleed the bottle completely and then go a 1/2 CW to decrease it, then fill again and shoot some pellets to let the reg to settle again, then turn the screw CCW until you reach the factory settings again…. the bad grouping can be because of the unbalance between the HST and the REGULATOR PRESSURE, if you increase pressure, yo may have to add some hammer tension to keep it all balanced and achieve the same accuracy.

    i think the regulator pressure is to low for a .30cal…. sometimes valves are not able to seal because of the heavy hammer pushing it forward, if .25 edguns regs come from the factory at 135-140 bar, i think the .30 is designed minimum to work with something around 140-150bar….increase the reg pressure and when filling it again, cock the gun and that way you release the hammer pressure on the valve…

    it can be the orings that goes on the piston of the regulator, these orings are the ones that seals after each shot, if one of those is not working, your rifle may work as a NON regulated rifle.

    i will go with the Bantam XR magnum, very reliable, accurate, simple, adjustable, good looking rifle

    maybe the oring on the piston of the regulator is not good, that causes air pass directly to the plenum and the hammer is not capable of opening that valve with 300bar in his back

    if it is the latest model with the updated GCU unit, its something wrong, if not, its all ok, 810 on high power is the speed of a friend of mine red wolf rosso with the mentioned pellet, new gcu will give you a 20% more energy, for that rifle its better to use the jsb kings 25.4 in all three power configurations!!!

    HST on these HP Wolverines is fixed, here you have a valve opening adjustment, the hammer in the front side (the one that makes contact with the valve pin) have a screw, The more this screw comes out, the more the valve will open, to make this adjustment you have to have access  the hammer system and then loosen a set screw that secures this screw that I am talking about, then through the back of the hammer with a allen key (not sure if it´s 3mm or 4mm) you can turn it clockwise to expose this screw and it will open the valve more and increase the power, you must be careful as this can compromise the efficiency of the rifle, I found that the best configuration in my case was to set the regulator at 165-170bar and adjust that screw until reaching a speed of about 910 fps with the redesigned jsb monster pellet, Although the regulator is at 170bar, you can continue firing the rifle and it will give you a good consistency and will maintain the average due to the design of the hammer and valve, so it does not mean that you can only use from 250 to 170, in my case I keep shooting down to 140bar with no problem.

    firstable you have to bleed air off the system…. take off the bottle and take a shot just to bleed the plenum air…. then you will have to loosen a screw located on the right side of the block (this one secures the valve)….. at this moment, the hammer will push the valve forward because of the tension, unscrew the valve retainer screw (this one is located under the barrel and above the regulator)…… when re-installing it, make sure you cock the rifle before pushing the valve back in place (this way you avoid to bend the valve)… remember also to cock the rifle before screwing the bottle (otherwise the air will come out thru the barrel because valve is open)
