AEA Challenger Pro Long Barrell 30 CAL Settings / Tunes

Just got a 30 CAL Challanger PRO LB (Gen2) with the adjustable REG / Hammer.

Curious if anyone has tuned these yet and what settings they are running. REG came in at 170 BAR and Hammer all the way out. I'm getting 990 with the AEA 50.5 Grain pellets currently.

Also has anyone slugged one of the Long Barrel Versions. I've read that the recommended slug is a .303 but curious if this still applies to the Long Barell Version. Currently have some H/N 54grain HP slugs and they are .301 Thanks for any help / guidance

So far very impressed with the build quality. Going to get to go out tommorow for some accuracy testing.
