What's too heavy or just wrong for my .22 Marauder pistol?

Thanks for the continuing feedback, all. The polymags sure get endorsements. Super highly rated on Pyramid too. Hades as well. I think I'll wind up trying both at some point, but the polymags do look hugely popular ...

Are things like the Crow and Sniper Magnums too heavy to be properly pushed or whatever out of the Marauder pistol? I've read kinda vague mentions that lower-powered airguns shouldn't shoot super heavy pellets, but how low does it go, I dunno ...
 
This would be my most natural first thought too. Looking at how I'm really shooting, though, I don't shoot at much distance usually. 25 yards is about my max ... and I wish for the occasional 50. I'm sighted in at 10 and seem to hit the same at 15. Then it starts going haywire.

All this stuff is way more complicated than when I used to shoot 22 LR with iron sights. It takes some getting used to, and I'm definitely not there yet. Never even used a scope before now.

I agree with CTshooter. 

When I first got my P-rod I could shoot 27 yards at home and was zeroed at that distance.

I moved recently and have notes and stuff packed away but as I recall that worked out to be about the Optimal Zero on Chairgun given the speed I was shooting the H&N FTT's and my scope height. Gave me a fairly flat trajectory from 10 to 30 yards, which was about the PBR (Point Blank Range) calculated by Chairgun with a 1/2' kill zone specified.

The fact that my home range distance matched Optimal Zero on Chairgun was a coincidence. I would have zeroed in further away if I could have.
 
Barracuda hunter extreme on my Prod. 30 yard zero. It’s up there at 800+ FPS
