Huben Huben k1 25 jsb knockouts

[Cmurphy5583]

Has anyone used the knockouts in their 25 cal and how did it perform?

I tried them in my .25 GK1 and they were too loose, causing it to not cycle correctly and jam. I was told to try the .254 NSA 33 grain slugs, so those may be what's needed for the K1 as well. They are a bit cheaper than the JSB Knock-outs also. I just plaaced an order over the weekend and they should be here on Thursday. Then I will know for sure.

The .254 33g as @FLgunner said work well. I shoot them and the Alteros ATP-Smooth .254 in my .25 K1.

My GK-1 .25 likes the avs slugs in .254 and have had two K1 owners say theirs like them as well especially the 40 and 42gr flat
