MKI deep

[Crusher]

Has anyone found .25 MKI with the deep hole anywhere? I bought MKI and MKII and they are identical with shallow holes. PI says the difference is length. Well, unless I've forgotten how to read a caliper, there are exactly the same.

I can’t help you with a source but the difference is the skirt diameter, not the length.

I run across this from time to time. 25 4 Exact Kings. Externally all dimensions are the same, weight is the same and seam to shoot the same.

JSB isn't making the .25 King Heavy MK1 the same anymore(with deep cavity, and thin wide skirt). Pavel(manager of JSB factory) claims the difference in the two has only ever been a slight difference in the width, but as many on AGN have DOCUMENTED, that isn't true. The "new" MK1s look(and more importantly, SHOOT) like MK2s. 

Sad

Why would they bother then? Just discontinue them, or have they? Im still wondering if someone screwed the pooch on this one? What a mess really, some of us really had better luck with the mk1’s. It is sad!

Skirt diameter and cavity depth. And no, I don't think JSB makes the King Heavy (Mk1) anymore. Although they have gotten good at the big lie saying that in fact they do and the only difference is skirt diameter. Fact is the skirt diameter on the Mk2 and the Mk2 in King Heavy tins are identical. It’s sad because most .25 polygonal barrels shoot the King Heavy better than the Mk2

The bases/skirts of these pellets were plainly different at one time. And the cavities were deeper in the Redesigned pellets as well. I have not bought any of the MK1s as of late as my gun shoots the Redesigned better. Oops my bad pic is of the .22.

I guess I’ll just shoot what I have at matches then until they are gone. The Mk2 shoots ok but is less accurate for me. But the worst symptom is that out of 25 shot card, they throw one or two fliers 6” from poa. That could really cost you in a match. 
I guess it is coming down to changing caliber.

I’ll end up converting my DW from .25 to .30. I really like the .25 shooting King Heavy but JSB isn’t making them anymore and the gun isn’t accurate enough with the Mk2.

The 64 dollar question. ......

When can we expect to see replacement barrels ?

Crusher,
I am unable to PM so I am trying this…. I was wondering if you ever found a place to shoot. You mentioned in a post response that you are in Irving.
