CARM magazines for Impact?

I have them in .25 cal, I really like them for pellets but they don't work well for slugs. After trying them I personally would stick with the new sideshot version of the FX mags. Side shots are slug friendly, easy to load, twice the capacity and easy to buy. Carm was a great solution to the old FX mags but the new sideshot mags are night and day better in every way.
 
I have them for my .30 cal Impact and with pellets they work great. The largest slugs I can fit in them is the NSA 49.5 grainers. The 54.5 is a bit to long to load the mag. I have two,if you want to try one let me know.

Thanks, thats very kind of you! I'll hold off for now but appreciate the offer. Thanks for the info too.
