I got the new MK2 these days I didn't had a time not even mounting a sight on it. I would start tuning it with 34 gr JSB Match King Heavy but better me to do the porting mod first.

Anybody have a drawing with dimensionshow to modify the barrel and probe? I am a mechanical designer got used to it that I am doing everything by the numbers.
 
Thanks for the link. I didn’t know Huma was making these.

I ported my .25 Crown barrels and got great results. 34gr JSB maxed at 900fps at 150bar from 700mm stock. Ported got me up to 940fps. Now I’ve got the reg down to 140bar and it still sends 34gr at 920fps pw Max. Dial pw down to 4 and it just stacks them at 885fps.

Feeds pellets great no jams, haven’t tried any slugs yet.

I might pick one of those up just to try. I love the extra shots and I just like the shot cycle better at a lower reg pressure. 
I really wonder why FX doesn’t do this from factory.

Where did you get these? I would like to keep one original just for case.

The one from the left is the original, next is the one modyfied for the single hole TP, the one to the right is a pin prope for dual port that i made

A wider single hole probe vs a pin probe....did you notice a difference in performance? I have a pin style on my 22 cal, finding it a littlebit finicky pushing a pellet in the center noly vs the rear edge

9 euro shipping to Vancouver? Oh from krale. Get it from Bagnall and kirkwood should be better. Or check with Travis should have spare probes, got one from him a month ago.

Ordered the Huma parts only need one extra 25 probe for spare I will try with Travis. Once there, tinkering I could have a good use for the FX chronograph for first time setup, only cannot justify a pricetag for myself alone, I don't think there is a use for it later along the line maybe 2-3 times a year just to doublechek? I have a hole-ultrasound style chrony for couple years after a good tuning session I didn't touch it for a long time, me better check the battery doesn't leak....
