Lead BB's shot from a springer to scare Canadian Geese

I just ordered a tin of H&N Rundkugel rould pellets to shoot out of my HW30S. My hope is that I will be albe to put 2-3 of these in the barrel at one time so that they shoot slower than the 630 fps my HW30s shoots JSB 8.4 pellets at. I just want to whack the geese, not poke holes in them. Anybody have experence shooting the Rundkugel pellet? I plan to test the pellets by shooting at cardboard put out at 20 yards, the same distance I would be shooting the geese at. With JSB 8.4's, the gun shoots holes in soup cans at at 20 yards.

Hi all that replied,

I just fugured out that it was this post that earned me a Minus Accuracy mark and I'm a little bummed about that. I was in the wrong for considering using a HW30s to scare geese off my lawn, but as I said, I was trying to find a way to keep the volicity down to the point that it would just sting the birds. I also later said that I had given up on the idea after receiving a bunch of great feedback from y'all. I'm not a big poster, but I try to add valuable content when I do post, have done a few well liked reviews, had some great thread conversations with AGN folks, but the only Accuracy mark I have recieved was a Minus, and for something I ended up not doing. Anyway, I'd love to get out of the negative column at AGN and any suggestions or feedback would be appreciated.

Thanks!

Don
