    Really nice card! Keep going as you are on a positive trend. Indians or arrows? We always seem to be asking ourselves that question. Cheers, Greg

    30-Yard Challenge

    Hi Guys, I had to send my new Falcon X505 ft scope back to Falcon Optics. I was having trouble with the focus ring. They stepped right up and are sending me a new scope (thanks Nick). But that meant the old Helix went back on the NW Crown. Put it on this morning and reset the adjustable...

    Tom, You can get them from any supplier, just look for the 13.4 gr without the "Redesigned" label. I actually like the FX 13.4 gr as they are the old design and a bit cheaper. The shape is obvious when you see them side by side. (Phot below- a bit blurry but Redesigned on left "Trash...

    Rick, You might want to give the older JSB 13.4's a look. I found them to shoot more consistently out of the FX liners than the Redesigns. I have a friend who just received his Thomas Air .177 carbine, and he was told by the builder to ONLY shoot the old "trash can" 13.4 JSB's. Cheers, Greg

    Hi Guys! Spent a bunch of time today tuning the King .25 600mm with the 33.94gr pellets. I am getting close to a good tune at 50yds. Will now have to jump to 70 yds and see how it does. About 7PM I was putting stuff away in my backyard range when it dawned on me the wind had absolutely...

    Nice shooting Tom! II think when you miss by that little it could be so many things that it is almost random. Looks like the HM100x is a winner with those shallows. Cheers, Greg

    Steyr Steyr LG110 HFT

    Cavedweller, I like the Alpha Wolf picture! Does that scope rail have a built in MOA? There is a reason I ask. Where do most folks measure scope height? I ask that question for a reason. In playing around with various ballistics programs and trying to understand how they calculate...

    FX FX Wildcat MK1 and .177 JSB Redesigned Monsters?

    Hi, I did a bunch of testing of the 13.4 JSB pellets in my Crown MkII. It has a 500mm Superior pellet liner. I found the old type of 13.4 Monsters (the ones that look like trash cans) shot better out of that barrel than the redesigned ones. I am shooting them at 820fps for Field Target. I...

    30-Yard Challenge

    Tom, I signed up to go to the Pyramid Air Cup for Field Target. When I was signing up I decided that if I was going to drive 7 hours and stay 3 days I should go ahead and join all the competitions. So I also signed up for the 100yd benchrest and the Speed Silhouettes (aka Gunslinger). I...

    30-Yard Challenge

    Hi Guys, So it has been a while since I shot the Nordic Wolf Crown and today seemed like a good day. After talking to Ed about his experiences at NAC I decided to turn my King into a .25 600mm pellet shooter for doing 100yd benchrest. That meant I put the .22 500mm barrel back in the NW...

    Ok, let me take a stab at it. Using my NW Crown as an example. With the stock hammer spring, the Huma 13-gram (4mm head) hammer weight, PW at 17, reg at 90 bar and the internal hammer spring (IHS) adjuster sticking out 4 mm the Potential Energy available for striking the valve pin is 490Nmm...

    Tommy, What do you want to know about the Crown MkII :giggle: ? Ed has one that shoots great and I have a .177 and a .22 that also do. Tom Carlson's shooting with his Crown on this thread motivated me to purchase my first Crown. I love to talk about that rifle. PM me if you can stand me...

    30-Yard Challenge

    Hi Guys! It has been a while since I shot a card with my HFT rig, so I thought I would see how it is doing. I have done really well in HFT so far this season (better than 90% hit rate😊, except for offhand where last time out I did 25% of those😒). Anyway shot two cards and the better one is...

    FX Anyone have a tune for .22 JSB MRD in a Panthera with 500mm barrel?

    ED, Good info. I will have to have a conversation with you about your experiences with the 100yd BR at NAC :giggle: . I tried ViperJoe's tune and I can get them to fly at those speeds. I need to tweak the tune a bit to close the ES and find the best groupings, but it was giving pretty good...

    FX Anyone have a tune for .22 JSB MRD in a Panthera with 500mm barrel?

    Solo, Thanks, that is good info. I know that the LW polygonal barrels come with different twist rates than their land/groove barrels. Based on the info I presented the 1:30 twist rates for BRK/Daystate on the .22 MRD's makes sense as it gives a slower pellet spin rps. It seems they believe...

    FX Anyone have a tune for .22 JSB MRD in a Panthera with 500mm barrel?

    Thank you all for your input! I tried the tune ViperJoe suggested, and it is much better than where I had been. Even at 150 bar for regulator pressure I was able to shoot 3 magazines before dropping off the regulator. The MRD's were running at an average of 956fps and at 50 yds the accuracy...

    FX Anyone have a tune for .22 JSB MRD in a Panthera with 500mm barrel?

    To LDP and Vetmx, Thank you for taking the time to respond. I appreciate your insights. I think I am probably asking too much to get the MRD's to shoot at 900 fps from a 500mm barrel. The Maverick I use to have shot them really well, but it was a 700mm barrel. I might try really slowing...

    FX Anyone have a tune for .22 JSB MRD in a Panthera with 500mm barrel?

    I have been trying to find an tune for .22 JSB MRD pellets in a 500mm Panthera. The barrel is a 1:24 twist standard Superior STX liner and I have the 4mm head 12 g hammer weight. So far I can get pretty good 50yd groups when I get the pellets to fly around 900fps. My problem is that all the...

    FX True Ballistic Chronograph - Testing & Results

    Michael, I believe there needs to be some clarification on how the TB Chronograph takes readings and displays the results. I had a conversation on AGN with one of the developers of the TB App about this very topic. The conversation started because I used the TB when I was shooting some of...
