I have the .30 cal Red Panda that was tuned for slugs directly from Karma. I shoot a 77 grain boat tail slug at 950 fps at 200 yards. I'm setting up the RP to shoot 200 yard bench rest targets.

Karma/Donnny FL presets the #1 regulator at 3000 psi and suggest that it should not be changed by the user.

However, my best tune for 77 grain slugs at 950 fps is to set my #2 regulator at 2950 psi. Now that I have a digital manometer on the #2 regulator, it takes an average of 1:45 seconds after each shot to obtain 2950 psi for the next shot.

The longer my shooting session, the longer it takes to get back to 2950 after each shot. The last shot I took today took 2:30 seconds.

I shoot tethered and have my external tank set to 3100 psi.

I believe it takes so long to refill the plenum to 2950 psi for each shot is because the #1 regulator and #2 regulator are both almost the same. 3000/2950 psi

As I mentioned, Karma/Donny FL does not recommend to make any adjustments to the #1 regulator. It's a pain the arse to wait 2 mins before each shot!

So, how do I do it? I just want the #1 regulator to be 10-20 psi higher or 3020 psi instead of 3000 psi.

There's a detailed thread on utube by pj Clark that will tell you exactly how to do it. It's not that difficult from what I seen. It's an 8 part thing. The one that says internals should tell you exactly how to do what your wanting. I'd suggest that since you own a 2400$ gun that you watch them All. I own a panda,and i did. Learnt alot from it also. Pj explains everything near about. If you type Redpanda in utube,the vids will pop up.

I do believe on the slug guns the second reg is wide open,or should be. My pellet version of 30 caliber second reg is at 2800 while first is at 1900. Refresh is instant for 24 shots from a 4300psl fill.

I followed PJ's YouTube video instructions very carefully.
I elected to turn the adjustment screw 2 1/2 revolutions in hopes that it will increase the #1 regulator to something above 3000 psi.

Regretfully, the #1 regulator remained at 3000 psi. "wide open"????

I send Karma a email from their website to help with some additional help in the matter.

I have over 2000 slug shots with the .30 cal RP and could not figure out for the "life of me" why I had so many random shots. It was not until I installed a Sekhmet digital gauge on the #2 regulator did I discover that my shots were never consistent!

If I did not wait 1:30 to 2:00 mins between shots for the #2 regulator to reach 2950 psi, I would get an erratic flyer shot.

All this time I blamed the wind, slug weigh or me for the bad shot!

I have high hopes that Karma will figure this out. In the mean time, everybody that has a .30 cal RP for slugs and shoots heavy 77 grain slugs at 950 fps should go out and buy a Sekhmet digital gauge. It was only $35 and I also ordered the right angle adapter so I can read the gauge better.
