This report covers:

  • Why go to the effort?
  • Ten shots in 0.2-inches at 200 yards
  • So what?
  • Other airgun breeches
  • Always liked single shots
  • Summary

I am writing this report for a number of reasons. The main one is because all you readers are interested in accuracy, and today’s topic is an important component of that. Yesterday reader Vana2, who goes by the name Hank, asked me if the Daisy 499 could be converted to a magazine. Here are both his comment and my answer.

——————————————
Question about feed mechanisms and accuracy on the BB guns…
The 499 billed as the most accurate BB gun and it is a single shot muzzle loader.
Considering that steel BBs are not likely to be deformed in the magazine and they are held in position with a magnet, would there be any technical reason that the 499 could [not] be magazine fed?
Just seems that muzzle loading is a little inconvenient.
Welcome to July… Happy Monday!! 🙂
Hank
—————————————————
Hank,
That tight barrel is the reason for muzzle loading. Did you know that Harry Pope built his breechloaders to have their bullets muzzle loaded? It was for a different reason, but they were called muzzle loading breechloaders.
That said, I suppose a magazine would be possible. But target arms are typically single shot so I guess Daisy never saw the need.
If I hadn’t argued with them in the 1990s, they wouldn’t have ever sold the 499 to the public. They didn’t think people would pay the price, and were shocked by the response.

When I told him that, I figured it would raise some questions, so today I want to discuss bullet-to-barrel alignment and fit, which in our world is pellet-to-barrel, most of the time. read more

This report covers:

  • First comments
  • Bubble Leveler
  • Collar Buttons are a no-go at 100 yards
  • 210 SWC is still a great bullet
  • Balle-Blondeau-talk
  • Balle-patent
  • Balle Blondeau
  • 355-grain flat point dogbone
  • Ton shoots at 100 yards
  • One more test

I had the Umarex Gauntlet out to shoot at 50 yards last week but the day was just too windy. Once I got it sighted-in for 50 yards the wind picked up and blew the pellets all around. I wanted this test to be a good one between the magazine and the single-shot tray, and it wasn’t going to happed this day. So I brought out the TexanSS that has no difficulty shooting in the wind.

Today I will show you how the AirForce TexanSS big bore performs at 100 yards. I have spent several days at the range to get today’s results. That’s why it took me so long. read more

This report covers:

  • Initial tests
  • Accuracy
  • Velocity
  • Feeding reliability
  • Unplanned test at the NRA Show
  • Hard targets with a BB gun!
  • Simple test
  • Serious test
  • Summary

This report has awaited the launch of the Air Venturi Dust Devil BBs. That happened last week, so they are now available to purchase. If you are a fan of BB guns, you need some of these!

Initial tests

I was sent a sample of these novel new BBs when they were still in the pre-production stage. The first thing I noticed was the broad band around the middle. It obviously has something to do with manufacture, but I wondered what affect it would have on accuracy and velocity stability, so those were the things I tested first. read more

Today I moved back to 25 yards to test the Sheridan Supergrade. There were also a couple extra tests readers asked me to do and they are included in this report.

The test

I shot with the rifle rested on a sandbag. I pumped the rifle 5 times for every shot in today’s report. I also wore my reading glasses to make the front sight as sharp as possible. The bullseye became a little fuzzier than usual, but I think you are going to see that it didn’t matter. read more

Today’s report came to me as I was planning to test the accuracy of the Umarex Legends Ace in the Hole revolver. I have so many tests waiting for my time, but today’s report had to come first.

Gentlemen — we are living in airgunning’s Golden Age. I know I have written that many times, but today I would like to reflect on all the good things that are happening in our world. Let me start with the Price-Point PCP.

Price-Point PCP

When I got into precharged pneumatics in 1995, I was dragged into it kicking and screaming. No PCP rifle cost less than $600 in that day (think $900 today) and the high-pressure hand pump had just been invented. I had to use a 3000 psi aluminum scuba tank that cost an additional $120 and I had to beg the local dive shop to fill it for me. I actually created a release form that I signed and left on file with them to absolve them from all risk of selling air to a non dive-certificated person! That might sound extreme in 2018, but in 1995 that was the way it was done, and plenty of dive shops refused to sell us air. read more

  • Pre-work baseline
  • RWS Hobby
  • Harsh firing cycle
  • Rifle is breaking in
  • Air Arms Falcon
  • Sig Match Ballistic Alloy
  • RWS Hobby again
  • Discussion
  • Cocking effort
  • Trigger pull
  • Summary

Today I will test the velocity of the B3 underlever that we cleaned and lubed on Friday. This will be a fantastic learning lesson for all airgunners, because the results are most informative!

Pre-work baseline

If you have been following this report you know I discovered in Part 2 that the rifle wasn’t performing to expectations. In Part 3 I replaced the breech seal and tested the velocity. That gave us a baseline we can use today for a before and after comparison. Let me get to the tests right now.

RWS Hobby

The first pellet to be tested was the RWS Hobby. In Part 3 Hobbys gave an average 617 f.p.s. with a 24 f.p.s. spread. read more

This report covers:

  • Gunfun-1 was right!
  • The Urban
  • The issue
  • The silencer
  • JSB Exact Jumbo
  • The baffle
  • The fix
  • Groups with baffle in
  • Point of impact moved 2-inches to the left
  • Last group
  • Conclusion

Gunfun-1 was right!

I will open todays’ report with an admission that reader Gunfun-1 was right about the Bug Buster scope on the Gauntlet. It worked well at 25 yards, but I tried to shoot the Gauntlet at 50 yards on Friday and the thick crosshair of the scope had me guessing by 1/4-inch where I was aiming. Also, the image at 50 yards wasn’t as clear as I would like. So — GF1 was right and I was wrong about the right scope for the Gauntlet. I will change scopes for the 50-yard test.

The Urban

There is a lot of interest in the .22 caliber Gamo Urban I’m testing. I’m glad to see that the conversation remains civil and open to change as the test progresses. The Urban is a great new PCP and I want to give it every opportunity to perform at its best. read more
