Hi guys I’m trying to tune my 30 cal Panthera 700 to some heavier slugs but i can’t get them to fly any faster than 942 fps.
The gun came from Utah Airguns tuned for 44.5 grain hybrid slugs at 950 fps. 110 bar 3.0 hammer spring tension
According to “The Ultimate Airgun Tuning guide” on YouTube airgun slugs stabilize at around 950 to 1050 fps.
I tried tuning with 65 grain Griffen Slugs and at 110 bar they were way too slow.. so I gradually increased reg pressure up to 131 bar and the fastest I could get them to fly was 942 FPS. Increasing to 140 or 150 bar caused the speed to decrease. So I thought increasing reg pressure should increase the speed? Why Is that not happening? Is there something wrong with my gun? And yes I tried high, low and medium settings on the hammer spring tension but 942 fps was the most speed I could achieve. I’ve also since tried to tune with 70 grain eviscerator slugs with similar results.
I’m new at this and have a lot to learn. Thanks
