Required to Shoot Good

To shoot AP good, the shooter must have steady hands and good eyes. Steady hands are, in part, a skill that can be learned through practice. Good eyes need the right corrective lenses for some people, but are also in part a skill to use what you see, as much as seeing well. You have to know what to ...

Steyr FP dry fire

I have a Steyr FP, which has the barrel attached to the front of the trigger guard so it really recoils straight back. The striker hits the top of the same straight bar that raises to cover the back of the case in the falling block action. The firing pin is just a little bump on the bar. So the meta...

Good FP at low price is always a Buy!

The features of free pistols in general are: 1. Custom grip fitted to your hand. 2. Very light trigger pull. 3. Long sight radius. The custom grip, you do yourself. If you want to minimize your work, or at least make sure it will be possible to achieve a good fit, the original grip (whether previous...

Sticky Chinese air pellets

Someone gave me some Chinese pellets a couple of years ago. 1. Accuracy was the same as any other - I never could tell any difference in accuracy between pellets. Not that I ever tested in a solid rest. 2. I strongly prefer not to buy anything from China when I don't have to. In this case, I don't h...

IZH-46 minimum trigger weight?

I know someone with a new IZH-46 air pistol. The instruction book says not to adjust the trigger pull weight to less than 24 ounces. This seems strange, since the international standard is 500 grams which is about 17 ounces. I didn't measure the present adjustment yet. Is there some good reason to s...

How They Work

1. It doesn't matter how "sensitive" the microphone is, to measure to the nearest 1/10 point or better. The speed of sound is about 1100 ft/second. At 20 KHz frequency response (any good microphone), the length of a complete wave form is about 1100/20,000 = .055 ft = 0.66 inch. However, th...

Weights on ends only

To get maximum jitter dampening, while using the least weight (to more easily hold the pistol arm up), you should put your added weight at the ends of the pistol. This gives much greater angular momentum than the same amount of weight in the middle, but is just the same for static balance. The grip ...

Check the Parallax!!

Before buying any dot sight (or probably any other kind for that matter) for pistol shooting, check the parallax. If you can't check the one you will buy (mail order for example), at least check another one of a similar model. You don't need a gun to do this. Set the sight on a table or counter top,...

"Without more data, yes, I would leave the sights alone." Yeah Nicole. Us engineers should stick together. The writer who said it is incorrect to assume a static condition, is correct on that point. Which is why adjusting the sights after that group would be a bad idea! The shooter already...

Don't adjust the sights!

The main part is contained with, and nearly fills, the 9 ring, and crosses the 10 ring. As long as a group spans the 10, you can't get much better by moving it. The only way to improve is to reduce the group size until it no longer includes the center of the target, then move the sights to center th...

No, but it's a lot lower than it would be if the best shooters were using them. Most serious shooters prefer a compressed air gun, and they are not so expensive that any serious shooter can't get one. However, except for pumping it on every shot, the IZH is an excellent gun and can shoot as well as ...

I like my pump

I have a Gehmann hand pump. It has had no problem since I bought it, except that on a trip I once broke the pressure gage. The gage is a screw on device that can be purchased at industrial supply stores, however the pump dealer gave me a new one. My pump is easier to pump, per stroke, then some othe...

Most Natural Grip Position

From your original grip position, turning the gun so it is now properly aligned might have made it more or less comfortable and "natural" feeling than it was. If you no longer have enough contact between the base of your thumb and the side of the grip, you can make a "temporary" ...

For any gun, you can move the sight adjustment a whole bunch of clicks, like 20 or 100 or whatever it takes, moving the point of impact all the way from one side of the target to the other. Then measure the distance between your groups and divide by the number of clicks you did. I like to calibrate ...

Eye Exercises

Sounds to me like the See Clearly Method. I have no idea personally whether or not this system works, but in general, moderate exercise of any muscle might help, while extreme exercise can damage something. The See Clearly advertising indicates that glasses make the eye worse, but eliminating the ne...

One problem with printing your own target, especially for air pistol, is that nearly all paper has fibers that make it tear instead of punching clean holes. If you shoot pointed pellets, the tear will start at the point, so you can easily see where the center of the pellet hit the paper. I use only ...

As said, the .32 semi-auto is the standard pistol for international center fire. However, most of the people I talked with at Camp Perry do not like it much for Bullseye shooting. At that time, the European guns were optimized for 25 meters, and by 50 yards the slow barrel twist showed up as poor ac...

Star swaged bullets are excellent, my favorites once loaded. If you are shooting 45 caliber, you can get Star hollow point 185 grain which are the same external shape as normal 200 grain solid SWC. LaserCast cast bullets are just as accurate in my experience. I usually use the LaserCast because they...

If your eye lens is perfect, then whatever you focus on will NOT be any clearer with the iris. With the iris, depth of field is improved, so items you are NOT precisely focused on WILL be clearer with the iris. So although you cannot see the front sight any better, or the back sight any better, you ...

Adequate accuracy

For bullseye shooting, a 1911 .45 is considered really great if it will fire 10-shot groups of typical 1-1/2 inch size from a Ransom rest at 50 yards. With the right ammo, my Pardini can probably match this accuracy, although I don't remember right now what group sizes I was getting with RWS Target ...
