Pelletgage
The Pelletgage comes in .177 caliber at the present. The holes are in a steel plate. A plastic plate above the gage plate helps guide the pellet head to the gage hole.

This report covers:

  • Description
  • The difference is obvious!
  • Head sizes
  • Every shot was perfect

The last test I ran on the .177-caliber Pelletgage (reported in part 3) was unintentionally flawed. I wasn’t sure at the time, but when my results were muddled and I examined the test plan, it was easy to see.

Description

The Pelletgage is a device that measures the diameter of pellet heads, so they can be sorted into groups of similar sizes. Pellets that come in the same package often have a range of different head sizes.

Shooting the Rocket Shot target

This report covers:

  • Rocket Shot target
  • Wind is bad
  • Emplacing the target
  • Loading the can
  • Crosman Super Match pellets
  • Shooting the target
  • Afterward
  • Overall impression

This report took me some time to schedule. I needed to find a safe place to shoot aerial targets with a pellet gun, and I needed good weather. We have had a lot of foul weather in Texas this year, so everything took time to line up. But last Saturday, it did.

Rocket Shot target

You first saw the Rocket Shot target in the Part 1 report on this year’s Malvern airgun show. I bought one with the intention of testing it for you and also putting it into my column in Shotgun News.

Rocket Shot is a spring-loaded soda-can-launcher that throws an empty can about 10-12 feet in the air when the paddle is hit. It sets up easily, loads easily and is more fun to shoot than I imagined. When I watched the company owners shooting the target on their website, it looked easy; but I’m the world’s worst instinct shooter, so I knew it wouldn’t be easy for me.

Safe backstops

by Tom Gaylord
Writing as B.B. Pelletier

This report covers:

  • Nothing is completely safe
  • Don’t need a backstop
  • Packed earth works best
  • Wood works
  • Synthetics can work
  • Shoot it
  • How big should a backstop be?

If I say “backstop” to some shooters, they think I’m talking about a pellet or bullet trap. But I’m not. I’m referring to the insurance you put behind the pellet or bullet trap to stop things when they miss the trap. Some people might take issue with that statement. They might think that nothing could ever miss a bullet trap. I have a name for those folks — beginners. Shoot long enough, and you’re going to miss the trap — I guarantee it. In a quarter-million rounds, I’ve probably missed my trap 100 times. Both numbers are estimates, so don’t quote me.

Testing the .177 Pelletgage: Part 3

Part 2

Pelletgage
The Pelletgage comes in .177 caliber at the present. The holes are in a steel plate. A plastic plate above the gage plate helps guide the pellet head to the gage hole.

This report covers:

  • Update
  • The test
  • Blind test
  • Interpretation
  • I called it
  • What to make of these results
  • Observations so far

Update

Before I get into the test, I received a message from the Pelletgage maker, Jerry Cupples, telling me that he has measured a large sample of the gages he has made – they’re all measuring 0.01mm smaller than what’s marked on the gage. In other words, a gage hole that’s marked 4.52mm actually measures 4.51mm, and so on. This holds true for all the gage holes in a gage plate.

So, in the last report, all the pellet sizes I gave you were off by the same amount. This is not a problem. All I need to do is change my pellet sizes by reducing all on them by 0.01mm after gaging.

Texas airgun show

Before we begin, I want to remind all of you that the Texas airgun show will be held on Saturday, August 29. There’s a link at the top of this blog page that takes you to the show flier for all the information.

On Friday evening before the show, the public is invited to attend a reception at the Texas Star Ranch and Retreat, located near the show. American Airgunner will film an episode of the Round Table and welcome questions from the audience.

We have dealers coming from all over the United States, including some major retailers who will have premium pellets, CO2 and other necessary expendibles for sale. A range will be available all day for the public to try different airguns, and we’re going to host the LASSO big bore airgun competition.

Shooting Chrony Alpha Master

Alpha Master chronograph
Shooting Chrony Alpha Master chronograph has a control box with display that separates from the skyscreens by 18 feet. These chronographs are shown with their light diffusers attached, but I don’t use them. Read why in the report.

This report covers:

  • What about the false triggering of the skyscreen?
  • Start screen — stop screen
  • Atomic blast wave
  • The solution to false triggering
  • How I use the new chronograph
  • Battery operated
  • Light diffusers
  • Summary

As you may be aware, I shot my Shooting Chrony Alpha chronograph with the Benjamin Bulldog big bore air rifle. It wasn’t the rifle’s fault — it was mine. There were other shooters on the range, so I had to place the chronograph about 10 feet in front of my position to get the skyscreens out from under the metal roof that hangs over the firing line. For range safety rules, I could not get closer to the chronograph. So, I was pointing the airgun to shoot over the skyscreens.

Testing the .177 Pelletgage: Part 1

Pelletgage
The Pelletgage comes in .177 caliber at present. The holes are in a steel plate. A plastic plate above the gage plate helps guide the pellet head to the gage hole.

This report covers:

  • Introduction to the Pelletgage
  • How it works
  • How can the Pelletgage be used?
  • How accurate is the Pelletgage?
  • There is a technique to measuring
  • Is the Pelletgage necessary?
  • What comes next?
  • Where to get a Pelletgage

Introduction to the Pelletgage

The Pelletgage is a precision tool that lets you measure the pellet head sizes. The device is a metal plate with graduated holes that accept or reject pellet heads. If a hole accepts a head, the pellet falls through and will usually be caught on the skirt that’s wider than the head. The holes range in size from 4.47mm to 4.56mm.

The Pelletgage does not change the size of the pellet. That is not its function. It measures the pellet head size so you can be sure they’re consistent.
