I need a Red Panda .30 slug tune for 75-78 grain boat tail slugs for long distance 200 yards

After 9 different heavy slugs (900 rounds) and countless different tunes, I'm close to my goal of splitting playing cards at 200 yards. The groups are starting to tighten up a bit. Winds today 10-14 mph left to right. Stay tuned.

I tried a bunch of different weights and couldn't find any that grouped well enough for me. I turned up the power and got better results but still not what I wanted. PJ at DonnyFL said they had the best results with the 52gr AEA slugs.
Drumie,
Just my opinion..................
I don't shoot competition. Just club range shooting at 200 yards

Again, just my option....................

One would think that since the RP has won several bench rest competitions, there would be tons of videos and valuable information here on AGN and the internet. However, besides all my AGN RP post and the 2 Youtube videos I made, there is NADA, Nilch, Crickets........

Again, just my opinion............

There has to be a Karma Red Panda "Secret Society" mainly made of pro shooters who are not willing to give up or share there secret tunes. This forces normal shooters like you and me to figure it out on our own.

I just shot my 2000th round today while testing 10 different slugs weights and shapes, 3 different hammer weights and 2 different hammer spring combinations.

I don't want to be a member of the "RP Secret Society" and will gladly tell ALL the AGN members the best .30 cal slug tune I came up with. However, at the moment, I don't want to lead anybody down the wrong path. I still have a few different slug/hammer/spring tunes to play around with.

Yes, I can split playing cards at 200 yards. but I don't its the best tune so far. I hope to post my findings in the very near future. In the mean time, my airgun dealer, "Sunny" at airgundirect.com was instrumental in sourcing these relatively and vaguely mentioned parts from the Karma.. Go ask "Sunny" if you need any RP parts.

I have tried 9 different slug weights with 3 different optional hammer weights and 2 different hammer springs. When you add several different #2 regulator settings and hammer adjustments, IT"S A LOT of testing! And still I decided what .30 cal slug tune is best. For the 200 yard card splitting, I used the following tune. 76 grain boat tail Rouge Precision slugs, #2 regulator 2900 psi, hammer adjustment (center mark), 950 FPS, 90 grain hammer with the optional heavy hammer spring. The stock hammer that comes with the .30 cal slug version has a 70 grain hammer and stock spring. The optional hammers are 90 and 123 grains and a heavy hammer spring. I hope this helps. Please post your best .30 cal setting to share?
