    Thormolds, anyone swaging with them?

    I’ll hopefully have mine to talk about it next weekend

    Sorting pellets by viewing

    Inconsistent raw material will certainly cause errors because production swaging tools are not perfect and have flexibility and clearances and I'm sure that material of uneven hardness will result in an uneven shape. The speed of the machine, wear condition of the swaging die faces, cleanliness...

    Sad day for me...

    Good luck. Provincial game law enforcement is spotty but stout. I hope you can resolve it and get back to doing good with the proper permitting in place.

    RAW HM1000X Accuracy

    I don’t. I just talked to him this week about chambering a barrel I have but this is my first one. David

    Do .177 Pellets Ricochet Off Metal Targets

    Oof. I watched that and it is dry. But well done. Here are my takeaways: Long story short, lead does not create fully inelastic collisions against harder / heavier targets. Like steel. The projectile or pieces of it will bounce back a little bit on an angle. How much bounce back and on...

    RAW HM1000X Accuracy

    Martin will chamber a custom barrel.

    How accurate is your chronograph?

    If there’s one thing I’ve learned in metrology it’s that really good numbers are rarely accidental. I’ve seen a LabRadar tick off the same velocity within 1fps 5 shots in a row (1000y BR competitor testing a really good load around 3100fps) so my conclusion is LabRadar is the gold standard for...

    How accurate is your chronograph?

    Does a NIST traceable chronograph exist? And why would it matter - it’s not like a slightly out-of-spec chronograph is going to mean much. Our ballistic models are still only approximations and shot to shot variance is much more significant. The chronograph accuracy studies I’ve seen have...

    Do .177 Pellets Ricochet Off Metal Targets

    My experience with ricochets is with field target.

    Pellet traps

    $ .02 I’ve done duct seal, all metal, plumbers putty, hanging curtains, and rubber mulch. Duct seal was lovely quiet but getting the lead out was a real chore and the lead comes out in thousands of little pieces with duct seal bits clinging to each one. So I was a fan until the day I cleaned...

    Do .177 Pellets Ricochet Off Metal Targets

    Yes they don’t always splatter into the target. I shoot JSB made pellets almost exclusively. I’ve had bounce backs hit me from a metal target. They might have been shreds of lead but they were still flying. Contain the ricochets. David

    An experiment I would like to see

    JSB Hades are basically a roughed up diabolo and they have significantly lower ballistic coefficient. Reynolds number describes the intensity of turbulent energy in a fluid flow. There are a few narrow ranges of Reynolds number where roughness reduces drag. Golf balls size and velocity happen...

    Microscope pictures of ZAN BR100 30 Cal 56 Grain Pellet and ZAN .30 Cal 45.5 Grain Slug

    Those skirts are definitely not clean and clear. How do they shoot?

    Buying from a new member

    I quit Paypal years ago. They will shut down accounts and refund purchases for no legitimate reason. As a buyer things are pretty cushy with them. As a seller they will stab your back. In the classifieds world, you'll eventually be selling as often as you buy and so consider yourself warned...

    1st PCP; projectile weight questions...

    There are slugs out there sized for mammoth power 5-shots-per-fill beast guns as well as high power pellet PCPs (which is low power for slugs) and everything in between. I'd start shopping in the 40-50gr range for a Panthera pushing 90fpe. Finding the right slug can be brutal considering how...

    1st FT Match

    "13. safety glasses (if the range requires it)" Safety glasses regardless of whether the range requires it. I took a ricochet of lead last season on a 15y target. They're not common and they aren't high power but they would mess you up if it went at your eye. You will miss targets between...

    Buying from a new member

    I rely mostly on regular feedback preferably both as a buyer and seller. I always include my phone number in case the other party wants to do a call and although I don’t always initiate the call I’m always happy when there is one. You get to chat up with another airgunner, talk about the item...

    I never need to clean my barrel -- am I the only one?

    Or it could be some barrels shoot better clean and other barrels shoot better a bit more loaded up. I’ve observed some situations where bits of lead stick to the bore and until they get shot out they will throw shots. A pull through resolved it. Not sure if it’s observable outdoors but on an...
