Ghost Thinking of going .177 for slugs

If you go 22 BRK slug barrel like I did, Altaros 40 grainers right at 890-900 is the sweet spot.

I got some Altaros slugs for my Pantera 700 .22. like you mentioned speed is key , they shoot well @ slower speeds as you mentioned, no need for super fast. The Jsb Knockouts in .177 are also a great light slugs & 980 fps
 
I am using the red spring and regulator is set around 140 bar 👍🙂

Do you use a different spring for the 13 grains? Is it better to have more hammer and lower reg for slugs or the other way around? Do you change reg pressures going from 20gr to 13gr? I appreciate you answering my many questions😀 I’m going to try and test tomorrow!

Sorry for all the questions

13 gr are shot on power level MIN and I then go up on the power wheel to shoot 16 gr and 20 gr 👍😃 No regulator adjustment 👍 Keep the questions coming 👍😃 That is how we learn 😉
 
17 on pw and 130-140 bar red spring i think they were doing 1030 fps
I wasn’t sure if I need to move down to the blue spring, not even sure what pressure range that is used in.

The 13’s were going too fast for the FX chrono to catch even on min. The 20 gr will go 950+ fps on Max @ 137 bar w/ red spring and 915 on pw 5. I’m using the pin probe also. I don’t think I can shoot both on one tune, but maybe if I lower the reg. It shoots tight groups with the Zan 20 at 25 yards, it didn’t like the NSA 20.5 and they chambered hard, and fps dropped from 930 to 875 but they are .178.

Give it a try thats 1 of the things i really like about the ghost its easy to tune and its not a pain to change things around a bit.
