Crosman 1720 and Zan slugs < 12FPE

I‘ve finally dipped toes in the murky waters of airgun slugs. Been reading lots, doing my research, evaluating reviews (taking most with a grain of salt). I’m not shooting 100 yards or making big power but I am constantly fighting the wind in my back yard range and want to see if the slugs will shrink my groups.
Also wanted the litest possible slug since they are said to shoot slower. Fortunately options are only a little more limited than finding a quality .20 cal pellet and I opted for Zan 10gr slugs.

Adding a pic of my 1rst go round with these tiny pills. Shot over the chrony while sighting in and very surprised to only see a 10-15fps difference! Decided to relocate the chrony to verify fps at the target but was falling off the reg by then so 10.5s peeked at last shot and Zan slugs shot progressively slower from 660s fps to 650 fps.

Interesting too, besides NOT slowing down appreciably, notice the slugs are cutting a much cleaner hole in the target.

As soon as weather permits I’ll be stretching things out in the back yard.
