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.
