Blodnob Valve…. wow
I was just messing around with my blodnob valve…. and I was getting around 1100 with 15.8gr JSB’s – I was adjusting the preload and tophat setting’s when I get a 1339fps shot – 62 fpe, with a 12″ barrel 😯
Going to give it a break for today and get back to it tomorrow – see if I can replicate that to make sure it wasnt an erroneous reading.

Its either my combro is going nuts or you shouldn’t have a Blodnob valve with minimum load on the valve spring because today I got readings in the 1300’s and even 1489 for 1 shot.
I screwed the tophat in quite a lot and broke out the Shooting Chrony (that I’d ONLY just put away…) – After a few different tophat settings I ended up with a tiny bit of pre-load on the Hammer and 920fps with 15.8gr JSB’s which is 29 fpe – Right where I want it.
Thanks Blod !
