Daystate Black Wolf

First time taking my BW to the range today to get it sighted. Small orange target is sighted at 25 yards. Top 2 splatter targets and the diamond paper target at the bottom left are 50 yard groups.

For the 25 yards sighters groups, I played with no moderator, Sumo Donnyfl, and Donnyfl Tatsu. Groups with Sumo is the best but did bring point of impact down just a tad. No moderator shot the second best.

Regulator is set at 145 bar from AOA shooting 960 FPS with hammer at MIN, using 25 grain monster redesigns. I didn't play with the hammer spring since that speed and pellet weight is where it wants to be. I am pretty happy with the performance.

What caliber?

When you lower the regular to 130 bar, how many shots are you getting from 250 bar fill to 200 bar fill? I noticed when the regulator is set at 145 bar stock from AOA, my air full drops from 250 bar fill to 200 bar fill in only 11 shots ( one magazine)

I don’t know what caliber you are shooting but, let’s say you’re using a .22, so the 145 is probably too high.
I’d start at 120 on the reg and power wheel at min. Chrono and repeat at each power wheel setting and record results
if you aren’t seeing any changes with the power wheel setting, increase reg pressure 3-5 bar at a time and repeat.
generally the lower the reg setting is the more efficient the air usage
sometimes you can benefit from using a different spring:

Most dive shops will not fill over 3000psi. That won’t give you many fills before the pressure in the tank falls below the fill pressure of the rifle.
Thats why I bought a Daystate compressor.

Dive shops in active areas should be able to handle 3,500 psi and their bank bottles are often up near 4,500 psi. SCUBA HP80 and HP100 tanks take a 3,450 psi fill.

I rechecked the regulator, it's actually 135 bar from AOA. Those gauges are too small to read without taking a picture. I didn't adjust anything yet, but just shooting over the chronograph, I'm getting 960 fps on MIN. and 970 fps on MAX in .22 with 25 grain pellet. When shooting on MAX, I can hear more air is coming out or wasted air, but increase in speed is minimal. Maybe the hammer spring is too strong for the low regulator setting, which opens the valve for too long?

I think the overall goal for this rifle is to shoot up to 100 yards. I have yet tried 25 MRD shallow skirt, 28.55 MRD grand, 34 grain jsb beast.

I also would like to put 10 pellets through a single hole at 50 yards! You'll be the first to know, trust me.

I can do that every time - I just make the hole bigger!
