    Snowpeak Artemis P15 5.5mm - location of hammer spring adjustment screw

    The one with the spacer to add plenum will work. Based upon my results with a Bullshark that was not working when I got it you probably only needed to replace the O-rings in the stock regulator to make it work. But a new Huma will be nice and you will be able to rebuild it easily if you ever...

    30-Yard Challenge

    Here's a leader board submission for my Stoeger Bullshark 22. 198 14X. Shot with my Vector Sentinel 8-32 set at 32X and using JSB 18 grain pellets at 830 fps. I got to it early today at 7am but the weather report still showed 4mph wind. I ignored it and shouldn't have. This is with the...

    Umarex Notos first shot is off

    I used to have and use a conventional chronograph but I shot it one too many times. Now I use one of my cheap chinese chronographs. The clamp on is completely dependable and the cheapest. But on some guns it shifts the point of impact so I usually use a tripod mount. As long as I am fairly...

    Question on filling small SCBA tank

    Filling a 6.8 liter from 3000 to 300 bar is a lot different from filling it from zero. Funny how the same compressor is less capable now that there is a CS5. But no doubt the CS5 would be less stressed with filling fairly large to large tanks. Run time limit may be a better way to manage...

    Giving Crosman Domed Pellets their due

    Ed, The tin I have is the domed not the "hollow points". I got some decent targets with one tin of the 10.5s in my P35-177 but then subsequent tins were terrible. That's one of the reasons I soured on Crosmans. I had the tin of 14.3 Crosman domed in the coffee table my Prod is in. It...

    Umarex Notos first shot is off

    I've never seen anything that big but my SPA guns seem to not like being 5% under peak velocity for the regulator setting. When I do that, my first shot does not go where subsequent shots go. Or where it was shooting when I put it away. My new-to-me Bullshark is doing that right now and it is...

    Snowpeak Snowpeak M60B .25cal Tuning Process

    I've gotten a couple slugs to shoot OK in a couple guns but never as well as that gun shoots a pellet it likes. So I just shoot pellets. I too have to quit when I make a mistake and/or things stop making sense. If I start to get frustrated, nothing good happens. When I increase the reg I...

    I,m thinking about getting a portable air compressor?

    I got a GX CS2 earlier this year. I've filled my guns a couple dozen times with it. I filled my Avenger once from completely empty. But usually I am filling my P35s from 150 bar to 250 bar. Takes about 5 minutes if I'm using the GX filter. 3 minutes without. If has never gotten hot...

    Stoeger Updated Warranty Replacement for XM1 Bullshark Arrived From Benelli Today

    The valve of the bullshark is smaller diameter and brass whereas the P35 poppet is plastic and bigger. But the P35 hammer spring cannot handle 150 bar unless the ambient temperature is low. No way it will handle 165. But I don't know where the bullshark will fail to be able to open the valve...

    Athlon Heras - Where to Purchase

    You are right that the retailer is not involved in a warranty claim for Athlon. Their form is available on-line. You just fill it out and mail it to them and they fix your scope or send you a new one. No proof of purchase or receipt or anything like that required.

    Stoeger Updated Warranty Replacement for XM1 Bullshark Arrived From Benelli Today

    I've had the regulator out of my Bullshark at least 3 times in the last week. It came to me non-functional. I've got it to work a couple times but then it fails again. My last "fix" was to replace all the O-rings. It's worked for two days now, we'll see about tomorrow. Last 21 shots today...

    Stoeger Updated Warranty Replacement for XM1 Bullshark Arrived From Benelli Today

    It isn't BriarpatchMtn's gun but my new-to-me bullshark in 22 shot a 194 with Crosmans today and my P35-25 with a P35X barrel in it shot a 198 less than a week ago. Targets are in the 30 yard challenge area. The lowest best score of any of my SPA guns is a 196 from the P35-177 last year.

    N/A 10 air gun questions from a new airgunner

    I bought my first airgun in 2020 but I have no plans to ever have them inspected or replace their airtubes. If you want to be conservative get rid of them after 10 years. I usually just put my guns away with the pressure they were at the last time I shot them. Sometimes I fill them back up to...

    Snowpeak Artemis P15 5.5mm - location of hammer spring adjustment screw

    What pennyroyal said is completely true. The way the Huma design creates extra plenum space is it pushes the regulator further into the air tube. That reduces the amount of full pressure air you can store. SPA sizes these guns for 22 caliber and the 177 has plenty of power as a result. My...

    Antifreeze in your pcp compressor?

    I use distilled water with water wetter in it and I don't change it in my Yong Heng. It is in a utility room off my garage. That area is not heated but it is attached to the house and it doesn't get very cold here in SC. But if the cooling water of your compressor could freeze I would add...

    Springer vs. PCP

    Perhaps. The latest spreadsheet of results for this year appears to be on page 160 of the thread on this website. The best springer score is a 192. The goal is a 200 and there are several of those from PCPs. My best score this year is a 198. Lots of higher scores from pcps. If springers...

    Springer vs. PCP

    Anybody that thinks springers are just as accurate as pcps needs to print out some 30 yard challenge targets and prove it. The only springer scores I've seen are much lower. But my poor view of springers is no doubt in large part because I've never shot a nice one.

    Giving Crosman Domed Pellets their due

    I still had to keep an eye on my 2 wind flags despite the wind being only 3mph according to the weather service. But adjustments were inside the 9 ring - so small.

    Stoeger Updated Warranty Replacement for XM1 Bullshark Arrived From Benelli Today

    Great news. I did a little work on a Bullshark that got replaced under warranty because the baffles in the shroud got damaged. I think the baffles do a great job making the gun quieter especially for the small space they occupy but if the shroud gets loose at all and allows them to shift they...
