So you can consider this a comparison but I have a 25 cal cricket that shoots the jsb kings at 925 fps hole in hole at 30 yards. Using that as my baseline I have tried the NSA 26.8 grain slugs and they shoot 865 fps with a 3” group at 30 yards. I have not gone out farther but I think I need more fps. Pretty soon I’ll be sending her to Charlie at Georgia Airguns for a power tune. But back on topic, so the hades shoot ok out of the cricket 1inch group 30 yards at 905 fps with a few flyers here and there and I always feel like I have to readjust my zero when I shoot. Now the polymags have blow my mind, hole in hole at 30 yards I have not chrony it but I can imagine that it is from 900 to 925 fps. They fit in the mags and I can see that these may be my go to hunting round until I get my power tune. But I don’t see many ppl talking about them anymore as much as I used to. For me the polymags are better than hades. Has anyone else have similar results.
