Jsb king heavy mk2 in rpb barrel

[Achilles_13]

Hey everyone

I ordered 5 cans of what I thought was jsb king heavy but just noticed that I ordered king heavy mk2… It was a rush job and must have missed the mark.
Has anyone on here used these in their .25 rpb barrels? I have not tried those yet and am wondering of I should just immediatly return them. My p3 loves the mk1’s and as it’s quite a purchase I’d kove to hear some experiences from other users… thanks!

If your gun likes the MK I the MK II's will PROBABLY be fine. My Royale 500 shoots both very well but I'm not familiar with the rpb. If you want me to send a handful to try (so you don't have to open your new tins) I'd be happy to do that for you. PM me.

EDIT: Just noticed you're in Belgium. DOH! I think my offer might be cost prohibitive.

Thank you for the offer! cost prohibitive is the right wording for it. I’ll just try some and if need be send the rest of the cans back. let’s hope this was not a expensive mistake at almost 20 usd per can it’s because the mkI’s and my current slug of choice are bang on at respectively 40 (mkI) and 55 (slug) yards without any changes having to be made to the scope. If the mkII’s have too much horizontal difference to the mkI’s they’ll go back. Thanks again for the kind offer!

I don't know your barrel, but I know both the MK1 and MK2's pretty well, the group size @ 100 about a same .
Only difference is in the skirt thickness. Also don't mix them up. If you shot a mag of one and right next a mag of the other one, you will notice a POI will be higher @ 100 meters for about 2" high right about 2 a clock.

No worries. I'm hoping the MKII's will work well.
