It’s for second regs and to get less fps spread overall.

Mk3s

For those that have done both- do you find rebuilding/polishing an fx reg is as good(better?) than just replacing with huma regs Thanks Joe

I tried this a couple of weeks ago with some 22 slugs. Problem was the medium( walnut shells )got stuck in the hollow point and was tough to get out. Still thought this was a good idea and planned to try with a very fine glass bead for a short cleaning as too long might deform or change...

Has anyone out there takes a Lilja barrel blank and machined to use on your air rifle. I’m contemplating switching my 22 caliber impact Mk3 in such a way. Thanks Joe

Regs like yours. Macro 16 and micro around 4 and valve same. 830 absolute max even playing with micro and valve. Are you getting good accuracy with yours? I’m talking consitent 1/2” (+,-) at 50 yards

Looking for accuracy tune numbers for a compact Impact Mk 3 shooting jsb 25.39 redesigned Don’t want to change to longer barrel setup and figure someone’s figured out. I’ve not been successful as of yet Thanks

I apologize as I should have perhaps poised a different question. I’m familiar with a number of different associations targets. Just wondering who’s is the smallest. If I’m practicing, want to make as difficult on myself as possible😉

Would like to get the dimensions of the smallest target used in one of the “better” known organizations 50 yard matches. thanks

Sorry, to clarify, I’m only addressing differences in accuracy. Thanks

Read quite a few articles about this but here goes. If you have equal velocity in a 500mm vs 700( or now an 800mm) is there any inherent benefit in a longer barrel? I’m getting the impression that if each tuned correctly they will be equal and possibly the 500, having less harmonic...

Not trying to poke a hornets nest here but I would truly like an explanation how deformed, different weights, etc can all fly the same. Is it all in the barrel and/or rifle itself or ? The group in the first picture is beyond impressive to me and would love any hint as how to achieve anywhere...

I appreciate the responses No moderator being used as I thought that might be the issue. Changed scopes also. Tried regulator up to 160 bar and various below, different hammer settings along the way. Yesterday I tried 125 bar with the hammer spring adjusted one full turn in from flush and...

Sorry, I’m shooting at 50 yards and I’m not a formal benchrest shooter. Just a simple sandbag front rest.

I’m set at 125 and flush with hammer spring screw; 970 range with the 18s. I’ve tried too many tunes to go through with the 25s, to the point where I wasn’t sure if there was something wrong with the rifle. I still am not totally confident that there isn’t however I’ve been getting fairly...
