    Air Rifles

    Here is a purpose built 50y BR slug rifle. It’s a Thomas HP shooting 40gr slugs. Wind drift is similar to rimfire and accuracy is getting close. I’m averaging 248 on the Wrabf 50y card. Last 3 cards with this barrel was a 749 49x in 3-5 mph wind. Cost per shot is 2 1/2 cents...and you...

    50y BR with Thomas HPX

    Unfortunately....I really don’t know what’s exactly different. I can only make assumptions based on things I do know about the two. The Rimfire cartridge makes a very small volume of very high pressure. I have read that it’s up to 20,000 psi. Your bullet accelerates very quickly and then...

    50y BR with Thomas HPX

    Hi Tim, I think the larger SD is due to the muller having more taper and more overall friction. I can make my slugs from .222-.224”...and have tried them all. Any smaller than .2225 and accuracy deteriorates...and anything over .2230 with throw fliers. I have gotten the Muller to hold a SD...

    I use them to slug barrels all the time. Mike

    Here is a video of the slug making process....and the last pic that I couldn’t add to the last post. http://www.youtube.com/shorts/BIWzyIdob0Y

    Here’s a pic of my rifle and 3 cards shot with it a few days ago. Also a pic of the projectile. I’m shooting around 850 FPS and these produce a measured BC of around .130. Pretty close to the typical Rimfire bullet. The most attractive difference is that these swaged slugs cost about 2.5c...

    50y BR with Thomas HPX

    Hi Joe, I’m really hoping this goes somewhere. The Rimfire guys seem open to letting us shoot with them as long as we shoot the same target and distance. Makes perfect sense to me. You have shot Rimfire, so you know where air needs to be to keep up. We have our work cut out for us if we...

    Tim...the slug and accuracy game is in its infancy. It’s just been about 6 months since I have personally been working on getting something to be BR competitive. Lots of guys shooting slugs out there...but they have not been shooting good BR scores with them at 50. Pellets have been more...

    I think the RFBR guys and the 25 and 50m air rifle BR guys think similarly. I would love to be able to compete in ARA and IR 5050 matches with air and slugs. It would give the air guys a lot more places to compete. Mike

    Air rifle BR clubs are few and far between. Most of them kinda keep to themselves...meaning they are not too willing to travel to an event if they have a place nearby to shoot once in a while. There are some homeless shooters like myself that have nothing within a 12 hours drive. They look...

    This may be considered a dumb question....but would you consider allowing an air rifle competitor just for fun? Mike

    50y BR with Thomas HPX

    I would like that. I’m not necessarily opposed to an 8 hour drive if I can learn something. I’ve done a lot more for a lot less. ? Mike

    50y BR with Thomas HPX

    Hi Landy, The original post from a while back was using manufactured slugs. They behaved oddly and did not fare well in a variety of wind. At that time, I would have still shot pellets in a 50y BR match. What I’m using now is a homemade slug that is performing reliably and predictably...

    50y BR with Thomas HPX

    Hi Pedro.... hope all is well with you. I had heard about the addition of 50m air rifle. I agree that they won’t allow the use of slugs...will be too much to swallow right off. My hope is to get some participation here in the US for 50y BR with slugs. If they can be made competitive with...

    Air Strippers - Do they work?

    I’ve never seen one yet that has improved a great shooting gun. There are lots of reports that they have made improvements for some...but the scores do not support the claim. I use a muzzle brake on my high power pellet guns just to remove recoil. They don’t hurt the accuracy with pellets...

    50y BR with Thomas HPX

    Hi Landy...thanks. The targets were shot horizontally. It’s a lot of vertical. The wind was averaging 6mph and bouncing between 5 and 7 o’clock. I’m not able to hold a good velocity spread with this barrel no matter how I valve tune the gun. If I replace the barrel with a Shilen ratchet...

    I’m going to make them for the guys that are buying the rifle as a package for now. I’m not planning to sell the dies individually at this point. Mike
