This report is in response to a comment Pyramyd Air got from a customer who doubts that fixed-barrel airguns can ever droop. His position is that they can only have droop if the barrel is heated in some way (as on a firearm that fires very fast) or if the gun is assembled in a shoddy fashion.
He said he believed barrel droop is only commonly found on breakbarrel airguns, which is why he said he would never own one. He thought that droop was mostly caused by the metallurgy of the barrel.
Today, I’d like to address the subject of barrel droop in detail. It can be caused by many things, but poor metallurgy isn’t one of them. Barrels do not bend from cocking, despite what some people may think. It is true that a barrel can be bent by human force, but the force required to do so is much greater than the heaviest cocking effort on the most powerful magnum airgun. So, poor metallurgy is not a contributor to barrel droop.
Air Arms TX200 Mark III air rifle is impressive in its optional walnut stock.
Today, we begin our look at the accuracy of the legendary TX200 Mark III. Since the rifle has no sights, I mounted a Hawke 4.5-14×42 Sidewinder Tactical scope in two-piece UTG Accushot 30mm medium rings. These rings are tall for a medium-height ring, but the TX200 cheekpiece is so high that many higher rings will be just right and fit the shooter perfectly. I know they come very close to a perfect fit for me, and the 42mm objective bell still clears the spring tube by a lot.
I’m showing a photo of the rifle with the scope mounted because you’ll see that the end of the scope hangs over the back of the loading port. In a TX200, that isn’t a problem unless you have summer sausages for fingers, because the loading port is very large — but on other underlevers and some sidelevers it may be. The Hawke is not a long scope, so this clearance is something a new TX owner needs to consider.
It’s time to advance through the 20th century and look at open sights as they evolved. We now know that by the beginning of the 20th century almost everything that could be done to increase accuracy with open sights had already been done. There were a few nice touches that were added, but most of the hard work had already been done. But that didn’t mean the gun makers were finished. There were always new embellishments that could be added. Yet, some of the sights that were most popular in the 20th century actually got their start in the 19th century.
This series began with the earliest sights that were both primitive and simplistic. Then, we looked at the evolution of peep sights, starting back before 1840 and progressing to around 1903.
There’s a lot more to be said about both open and peep sights. It was at this point in time that they each began to develop along separate lines. I think I need to concentrate on one type of sight per report to keep things straight. In today’s report, I’ll look at open sights from around the middle of the 19th century until today.
Open sights evolved rapidly after the American Civil War, which ended in 1865. Not that all the innovation was done in the U.S., mind you, but that was a time when the world of firearms was advancing though technological stages, and the sights kept pace with everything. Other wars around the world at the same time drove the armies of many nations to push the limits of firearms; and we got smokeless gunpowder, fixed cartridges, breechloading arms and eventually repeating firearms from this era.
This is the second of my reports on the 2012 SHOT Show. There will certainly be at least one more after this, and perhaps even more, as there’s simply too much new information to pack into a single report.
The state of the airgun industry in 2012
Before I get to some specifics, I want to make a general observation. This year’s SHOT Show was different for me in a major way, because I saw for the first time that firearms shooters are beginning to understand airguns as never before. In the past, I always had to start my explanations with the cooling of the earth’s crust and then progress through the age of the dinosaurs because each firearms person I talked to thought of airguns as either toys or BB guns. This year, a lot of them were clued-in on what’s happening. They weren’t surprised by the accuracy we get, and they knew about big bores. A lot of them had some airgun experience and more than a few asked me the same kind of questions that I get from long-time readers of this blog.
In Part 2, we learned that the peep sight has been around for a very long time. But following the American Civil War, the entire world became intensely interested in shooting for about 60 years, and target shooting was at the top of the list. World-champion target shooters were regarded like NASCAR drivers are today.
Because of all this interest, the common peep sights that were already at least 50 years old, and perhaps as old as a full century, started to change. By 1870, designers were innovating again. One of the most famous innovators, and the man whose designs are still impacting battle rifles 125 years later, was Col. Buffington of the Springfield Armory. In 1884, Springfield selected his sight for the U.S. .45-caliber, single-shot military rifle — the gun we call the Trapdoor.
Today, we’ll look at peep sights. Do you think a peep sight is a modern invention? Wrong! Despite what Wikipedia says, peep sights date from at least as far back as the 1840s and perhaps even a half-century earlier. There were sights enclosed in tubes during the American Revolution (1775-1783), but those had not yet reached the full development of the sights I will discuss today. By 1840, peep sights were being offered by a great many rifle makers.
