Wolverine B Hi-Lite "regulated"

There is no way for me to control the tinker freak inside.

Well, I am waiting on the regulator. This explains the lack of an update.

I thought I would take a moment and explain my reason for wanting to try this. I am blessed to have a home that backs up to Corp property. I shoot every day from my back porch and can shoot from 0 to 125 yards. I have several fixed target locations with spinners and such as we'll as several logs littered with golf tees and acorns or paintballs.

I am sighted in at a far zero of 40 yards but enjoy stretching out to 93 yards where I have a fallen log with a spinner permanently installed as well as a holder for groupings...

I don't claim to be able to explain why, but my rifle definitely prints two groups at this range while at good fill pressure. At about 180 BAR +\- I see a shift that goes low left about 1.5 inch while shooting the 93 yard target. The really strange thing is that it is consistent for 20+ shots after getting to 180 BAR... Just low left about 1.5". At 60 yards and under, this is not really noticeable when shooting acorns or paintballs and a full 75-80 shots are very pleasing.

My thought is to regulate to 150 and eliminate the POI shift all together. On this rifle the difference in avg velocity at 230 BAR and 150 BAR is not significant. Chronograph says I am at 898 - 922 from 230 BAR to 150 BAR.

I have a 1/16" nylon spacer ring behind the hammer spring and backed off the return spring from full clockwise till I saw a velocity reduction.

The rifle is awesome quiet and very accurate. I love the rifle and am very happy with the results of a 30+ shot group at 93 yards. If a small investment results in a 75 shot group rivaling my current 30 shot group it will be a very worthwhile spend.

Truth is that I am not sure about the regulated air volume impact that will happen as I have not removed the bottle to calculate and can't till I have the reg on hand to measure. I am hoping the adjustment in the reg will let me adjust enough to maintain 900 +\-.

More soon.

All I can say is that the rifle has exceeded my expectations. Everything is now dialed in, polished and seated. I can fill to 280 Bar and shoot down to 150 Bar yielding 100 hits on a 1" dia spinner at 50 yards outdoors using unsorted JSB 15.9s. Shots #101 and 102 rang my 2" bell at 108 yards. We then came off reg and called it a session. I don't know what else one could expect from a .22 air rifle.

The rifle is shooting just a hair over 30 ft-lb @ 925fps.

For recreational shooting with friends or my kids this is the most pleasing I have owned or personally handled.

I am in middle Tn and have a great backyard bounded by corps property. I have a compressor Someone should stop bye some time. Air rifles only and they have to be well moderated. I have great neighbors; I want to keep it that way.

I covered my reg with some simple pipe insulation cause the big void just looks goofy.

At the time I ordered, one could ask for a specific setting. They are adjustable though and you can see the procedure on the site or on YouTube... Remember that the Daystate slingshot valve likes a higher pressure. I feel that trying to regulate a Daystate with a slingshot valve below 150Bar is going to be tricky if you want to maintain 30 ft-lb. Perhaps it can be done; I thought I'd let the valve work as designed and use a higher regulator pressure. 

Sharoff,

I would have loved to and probably would tell a better story had I done so. I tried several times and even put light bars on my chronograph with no luck. I am only able to gather data on 1 in 5-7 shots. It is very frustrating for me.

Nutcracker,

You could probably make a small spacer tube to put between the regulator and action. The volume after the reg is fairly small for a .25.
