## Ballistic coefficient: What is it? Part 2

Part 1

Last week I republished Part 1 of this discussion about ballistic coefficients because I was out of town helping my sister. I’m back in the office, but Part 2 of this report is necessary to close the loop. So here we go.

This report covers:
• Review
• Today’s discussion
• Round balls
• Conical bullets
• Smokeless powder
• A big point
• Shape
• Round balls — again
• The bottom line

I’ve taken 11 months to return to this subject of ballistic coefficients (BC). That was in spite of some tremendous interest in Part 1 of this report last May.

I’m purposely avoiding all discussion of mathematics, which is difficult, since ballistics is a discipline that heavily employs mathematics. But I’m not qualified to write about the math; and, more importantly, I know that 99 percent of my readers would be turned off if I were to write the report that way.

## Pellet velocity versus accuracy test: Part 11

by B.B. Pelletier

I’m posting a Best of BB today because I had cataract surgery yesterday and I couldn’t see the computer screen to write. I selected this article from December 30, 2011 because it’s the last of 11 experiments I( did on spring gun accuracy and pellet velocity. We seem to be interested in tuning spring guns, and this is a good one to read. Remember — there are a total of 11 parts. So enjoy!

I see it seems to indicate there will be another part to come at the end of this report, but I never wrote it. This is the last in the series.

Happy New Year from Tom & Edith!
One nice thing about watching a TV program is that it only takes an hour or less to view. You have no sense of the man-weeks of work that go into a short production on screen. Sometimes, the same thing happens in the world of airgun blogs.

## How does BB select pellets for a test?

by Tom Gaylord
Writing as B.B. Pelletier

This report covers:

• Don’t I wish?
• What’s the criteria?
• Brands first
• Choosing a pellet
• Target guns
• Action airguns
• Hunting airguns
• General purpose airguns
• Trick pellets
• How should you do it?

This blog was requested by reader Cobalt 327. And the answer is simple. BB gets paid by the pellet manufacturers to promote their products — the same as for the airgun manufacturers. The more they pay me, the more I talk about their pellets. I get a very healthy stipend from Crosman for writing about their Premiers, and from H&N for touting their Baracuda Match pellets. JSB actually sends me on all-expense paid vacations to the Bahamas several times each year, in addition to a very large check each month! Pocketa-pocketa-pocketa…

### Don’t I wish?

I know that’s what some people think. There are no kickbacks that I am aware of in the airgun industry. If there are, whoever is paying them is fooling themselves, because we writers do this because we love it. I do get paid to write this blog, but no one tells me what to write and I have never been told to give a product anything but an honest report.

## Why own a chronograph?

by Tom Gaylord
Writing as B.B. Pelletier

This report covers:

• No preaching
• Evaluate an old airgun
• Test pellets
• Evaluate a tuneup
• For detailed tuning and product development
• What it isn’t

Today is my cataract surgery. I don’t know how well I will be able to function online for the next several days, so will you veteran readers please help the new guys? I know you always do, but I’m just telling you what’s happening.

If you have read this blog for very long you can answer the title question for yourself, because I write about chronographs all the time. I use them for big things like testing the health of a new acquisition (the Sharp Ace Target and the Sheridan Supergrade), and things more subtle (testing the Air Arms Galahad).

### No preaching

I used to preach about when to use a chrono and when not to, but I’m not going to do that today. Use it whenever you like and for whatever reason suits you.

## 2017 SHOT Show: Part 3

• Air Venturi
• Lil Duke
• New Air Bolts
• Hatsan
• Semiautomatics
• Big Bore Carnivore
• Sun Optics compressor
• The year of the airgun

### Air Venturi

This was the first actual day of the SHOT Show, and the crowd was excited! I stopped at the Air Venturi booth first, so let’s see what’s there.

### Lil Duke

First up was the Lil’ Duke BB gun. As you can see, it’s styled after the model 92 Winchester John Wayne carried in a number of his most famous movies, including True Grit. This is the one he fills his hand with.

The Lil Duke is bound to become a favorite.

The John Wayne airguns have been quite successful for Air Venturi. They had a second booth upstairs this year where they showed a number of their other John Wayne handguns, including a 1911 that Wayne probably carried in the Sands of Iwo Jima!

Part 1

• What I saw at Sig
• What I didn’t see
• Bucket list
• Industry Day at the Range
• Gauntlet
• Havox
• Gamo Swarm Maxim
• Coyote Urban
• There is more

Inn this report I will cover airguns I saw at Sig Range Day on Sunday, Jan. 15 and at Media Day at the Range on Monday, Jan. 16.

### What I saw at Sig

Sig has been breaking into airguns over the past several years. This year they brought out the Max Michel 1911 that I tested for you back in November and December, plus they have now added the Sig P320 ASP pellet pistol. The 320 is unique in 2 ways. First, it has a 30-shot belt-fed magazine, so there are lots of shots on board. We haven’t seen a pistol with a belt-fed mag since Anics walked off the scene, years ago. This one is very slim, too.

The other nice feature is the trigger pull. Though it is a long pull, it is 2-stage and incredibly light. Yours truly was able to nail targets with this gun at respectable distances.
