I shoot later today aswell with 33.95 JSB and 33.49gr JSB knockouts with same tune. My gun should be tuned now for ~905fps for 33.95gr JSB pellets.Both examples are maybe kinda distorted, since the weight is so different between slug and pellet.
I had some slugs delivered today that are more similar I'm weight to the 25.4gr pellet. When I get a chance to shoot them I'll share the speed difference. I've since tuned the gun down to be more like 890-900fps with the 25.4gr pellets.
I don't expect the fpe difference to be quite so drastic when the slugs weigh about what the pellets do.
