SHOT Show

I’m at the SHOT Show today. Today is Media Day At The Range, so I’m looking at all the new airguns that are on the range in Boulder City. Yesterday I went to Sig Range Day, so tomorrow I will have a report on both events. The show opens on Tuesday, so the Wednesday blog will be my first report from there.

Today we look at the velocity of the Diana 27S we are testing. If you recall, in Part 2 the breech seal failed and I couldn’t test the rifle. I replaced the seal with a temporary leather one and the velocity jumped from the mid-300s to the high 600s. I said then that it was the largest velocity increase I have ever seen from just replacing a breech seal. I expected a gain of 60-80 f.p.s. Several readers made similar comments. read more

  • The question
  • Summary

Today we look at the Air Arms Pro-Sport with the Vortek PG3 tune kit installed at its most powerful setting. This test was suggested by reader Yogi in the comments to Part 5.

“To finish up the review, how about exploring the other 2 notches in the PG3 kit? Maybe one notch is full OEM power, second notch is the desired 12 foot-pounds, and the third one(the one you have it set on) is good for 10.5 foot-pounds.

This way you have a full report on the Pro-Sport AND the PG3 kit.”

I though that was a great idea. Unless I test it, who knows what the other notches will do? And also there are the two heavy washers that add weight to the piston and more tension to the mainspring. read more

  • Sig Match Ballistic Alloy
  • Gamo Match pellets
  • Vogel Match pellet with 4.50mm head
  • Discussion
  • Summary

Today is a day I have waited for for many years. This is the day I discover how accurate the Gamo 126 10-meter target rifle is. Let’s get right to it.

The test

I shot off a sandbag rest from 10 meters. I shot 5 pellets at each target.

R10 Match Pistol

First to be tested and also used for sighting-in was the 7-grain RWS R10 Match Pistol wadcutter. Sight-in took three shots and then came the group. The 126 put five R10 Pistol pellets into 0.314-inches at 10 meters. That’s not a very auspicious start. I expected better from this pellet. read more

  • Summary

Today is the day, airgunners. This is the day we open the .22-caliber Air Arms Pro-Sport we are testing and install a Vortek PG3 tune kit. It’s a drop in one-for-one replacement powerplant kit that promises to lower the cocking effort of the rifle and smooth out the shot cycle. The power output is 12 foot-pounds in .22 caliber which would be a 11.9-grain RWS Hobby leaving the muzzle at 674 f.p.s. And someone says, “Gee, BB, don’t you know you’re not supposed to tune for LESS velocity?”

Yes, I do. And this is exactly what I want. Even if I only get 625 f.p.s. with the Hobbys it’s what I want. Because I’m going for smooth — not power. read more

Well!

When I started the report on the Gamo Swarm Fusion 10X Gen II I didn’t know I was kicking a Texas fire ant mound! Part 1 of this report lead to a report on the history of Gamo, and that brought the show to a screeching stop! I won’t get into all that transpired, but you can read the comments if you are interested.

Another breakbarrel repeater

I’m not going to defend or criticize anyone in this report. All I’m doing is testing another breakbarrel repeater for power, accuracy and overall quality as it pertains to airgunning. With that in mind, let’s start the show. read more

  • Beeman Kodiaks
  • RWS Superpoint
  • JSB Exact RS
  • RWS Superdome
  • JSB Hades
  • Discussion
  • Summary

Today we learn how accurate the Daisy 22SG is. The rifle was already scoped so I hoped it would be close to zero, if not spot-on. I didn’t know what pellet(s) shot well in the rifle, so this test starts from the beginning.

The test

I shot the rifle off a sandbag rest at 10 meters. I shot 5 shots per group and pumped the rifle 6 times for each shot. In the velocity test we learned that 6 pumps pushes an RWS Hobby pellet out at around 500 f.p.s. That’s fast enough for punching paper.

Check sight-in

Since the rifle is scoped I first checked the zero from 12 feet before shooting from 10 meters. The pellet hit about an inch below the aim point and a little to the right. It was hand-held, but that was close enough to start shooting from 10 meters. I expected the pellet to rise at that distance and it did. It’s hard to say how much it rose because 5 Hobbys went into 0.925-inches at 10 meters, but the center of that group seems to have risen about 3/4-inches. I am not showing that group. read more

  • Summary

Okay — you are either for or against this airgun. There doesn’t seem to be much of a middle ground. I won’t take sides, but I am aware of all of your feelings.

BB feeding

First up is the “special” BB feeding method that I found quite by accident. I was reading the comments on the Pyramyd Air website and saw one or two complaints that the BBs don’t feed well in the new gun. With the older 760 I know they feed from the top inside of the receiver and you have to pull back the spring-loaded feed button on top of the receiver to get the BBs to fill that small magazine from the larger reservoir inside the receiver. My older 760 is a first model that holds 180 BBs. This new gun holds 1,000. read more
