Been looking at 420molds on accuratemolds and noticed these grizzly 425 carts. Don’t have a chrono and was wondering if anyone else has seen if you get an honest 1200fps on 420/425 pills in a 7.5” SRH

I get around 1150 with a 420 LFN GC in a SBH 480. That's a just below max load of H110 and a WLP primer. I think that same load would get you the 50 fps with the longer barrel you have.
