I was out in the shooting shed today trying out different pellets and nothing shot really well. I was shooting with the hammer spring 3 turns in from flush. I thought the 18.13 JSBs did okay so I tried those on a few different hammer spring settings.

Target 1 is 3 turns in, target 2 is 4 turns in, target 3 is 5 turns in, and target 4 is 6 turns in. The last target (5) I zeroed and the hammer spring is 5.5 turns in from flush. All are 5 shot groups @ 50 yards. 6 turns in showed the best group, but I might have got a little target panic after I zeroed it for the last group. 6.25 turns is the max adjustment.

I didn‘t show most of the other pellets because I don’t think they got a fair trial. They were probably moving too slow. I did however attach a photo of the CPHPs. I think they show potential. This was also 5 shots @ 50 yards with the hammer spring 3 turns in. Dime for reference.

I think it will turn out to be a sweet little squirrel gun.

My P35-25 has taken 18 squirrels, P35-22 10, and the P35-177 21. All work great. The 22 is the most accurate but overkill for backyard work. I had the 25 for a season more than the other two so it took a bunch before they got a chance.

You need a chronograph. I use inexpensive Chinese ones. To tune you need to know the hammer spring setting that gives the most velocity. Then normally you would decrease the hammer spring to reduce velocity 5%. I like to try hammer spring settings both a little higher but mostly lower than the peak. My Avenger likes it a little higher and my P35s sometimes shoots the first shot slow if I go all the way to 5% under. So they are more like 3% under. But it all starts with knowing the peak velocity hammer setting.

I use a Shooting Chrony, optical shadow style, in my basement. It has the light attachment over the sensors so no worrying about outside light. I then do my target work outside. Yup you need a chrony so you can see what is consistent and what is not. Get some better pellets for long range. I know LLeon shoots crosmans at long range but he has his brokoks dialed in.

I have one and have used it but I prefer the little tripod mount because it doesn't impact my poi. The barrel mount does. I got the tripod mount from Aliexpress. Amazon at least used to have the barrel mount.

If you haven't tried H&N 21 grain I would. I use the Match because they are a little more consistent. I shot a 200 with them from my P35-22 and they were the most accurate in the 22 caliber bullshark I set up. They should be going 840 fps or so from your bullshark with the tune it came with. This is near the maximum it can do due to the hammer spring. But it's plenty for small game. I even took a small raccoon with these pellets in my P35-22.

Jim D , You are spot on w/ the Bullshark factory tune & H&N Match 21gr. I have stuck w/ 18 gr JTS or JSB at 885-890 so far though as I'm loaded w/ them.
Come warmer weather & the G-hogs are out & about I'll switch to the H&N 21gr.s & turn the hammer up one turn. I've got my hammer marked for easy reference. BTW, my reg was set at 145 BAR, I'm not changing it. I am very pleased with both of my Stoegers.
