Hello everyone! I've got a new Kral Empire X in .25 that is doing great with JSB 34s but I would like to try slugs as I have never used them before. Can I shoot slugs with it? If so, which to you suggest and what size? I know there are .25 but I've seen .217 as well. I believe Kral makes their own barrels so it's not a CZ or LW. My rifle didn't come with a manual and I can't reach Kral for the life of me. The manual that Krale sent over electronically was in Turkish so.....Any advice would be greatly appreciated. Thanks!
