Put Huma power tune plenum and regulator (set 150 bar) in my .25 cal Bullshark yesterday evening. H&N 30.84gn Baracuda's 796fps hammer spring all the way in. Went to range today and they don't shoot for s**t with any hammer spring setting. Obviously gun just doesn't like the pellets. Unfortunately only one's on hand at the moment. Good enough for plinking my 15yd spinner the my window though so they won't be wasted.

Put a bunch of .25 FX 26gr hybrid slugs through the HM1000x. The results were okay.

Tried my always good H&N Barracuda 30.8gr. At the current settings it REALLY likes the Barracuda. 45 yards and hole in hole or almost hole in hole.

But dayam does that gun eat a lot of air. Glad I figured out how to fit a 1.1.1L bottle on the rifle.

Did a power tune on my Zelos . Worked the reg , and hammer spring together gentle increases untill the 28 grain HP slugs were going 900 fps.
2750 on reg 5 turns in on hammer spring. That's it there is no more. 50.5 ft- lbs. Wanted 920 to 950 but will have to get , and use the 25g slugs for that.
Reason for fps increase want reach out 100 yards for accuracy test , and fun of it.

I put the dream Notos reg on my newer Notos. The barrel on this one is a little better than my old Notos. It’s averaging 765 fps with 15.9 gr. I haven’t ran a full string yet to see my shot count.
This is #1 plinker right now. Tomorrow I’m going to work on the trigger and mount my Athlon 10x. After that probably tuning the regulator/HS some time this week.

I also topped off my great white from 3200 psi to 4500. It was my first tank top off since getting the new GX filter. It did a great job with my CS4. I did two 20 min timers to purge. It was done before the 2nd timer went off.

Did some testing of my modified HM1000x .25. Currently has a 35cc RAW plenum and a 25cc plenum in the Huben Power Dream Universal regulator. 60cc total plenum.

I had initially set the regulator to ~2300psi and with the hammer spring all the way out was getting 1050FPS with H&N Barracuda 30.86gr. Reset to 2000psi and was still around 1015FPS. Reset to 1400psi and was at 915FPS.

Groups opened up a bit at 1400PSI/915FPS so I probably will step up to ~1750PSI. Have JSB King Heavy 33.95gr, H&N 42gr and 46gr slugs to try out too.

Aside from work getting in my way.

I swapped scopes on to my HFT 500. and made my Rowan side wheel work on my new Athlon scope.

I did some e mails about the airgun range.

Canceled one order for 34mm scope rings that were back ordered and placed another.

Shopped for a deep gun case .

Planned my range maintenance for Friday afternoon.

That’s about it.
