How to Dial-In Precision Accuracy with any Air Gun
Forget Velocity, Think Balance & Power!
First of all, to dial-in accuracy with any air gun, you must balance the weight of your pellet to the air pressure that your air gun is capable of producing. If the pellet is too light for the air pressure, you will not be able to hit anything; conversely, if the pellet is too heavy for the air pressure, you will still not be able to hit anything. On the other hand, you can obtain accuracy with a light-weight pellet by balancing it to a lower air pressure or have accuracy with a heavy-weight pellet by balancing it to a higher air pressure.
For example, with a .25 caliber air rifle producing 230 BAR air pressure, a 43 grain pellet will be accurate. At 25 BAR, a 19 grain pellet will be accurate. Reverse the air pressure for the two pellets and there be no accuracy no matter what you do. Once you have your pellet weight balanced to your air pressure, or your air pressure balanced to the weight of your pellet, you will be able to hit where you are aiming with predictable accuracy!
Secondly, if I give you a carpenter’s hammer, a 2×4 and a sixteen-penny nail, you can drive the nail through the board in three or four hits. If I give you a ten-pound sledgehammer, the same 2×4 and the same nail, and if you hit the nail perfecty, you can drive it through the 2×4 in one hit! The carpenter’s hammer is lighter and goes faster, but it does not have the power of the slower heavier sledgehammer.
I love the claim that a given air gun has a velocity of for example 1400 fps (feet per second). I want to shout out… “WITH WHAT WEIGHT PELLET?” for crying in the moon! I want to know the power factor of this gun- velocity is meaningless and it is only half of the equation without knowing the weight of the pellet!! Faster is not always better in the case of fixed power air guns. Forget velocity, think power! Note: anything over a 1000 fps is useless because the pellet begins to tumble like a football at kick-off. I have found when testing that the optimum speed for a pellet regardless of caliber seems to be in the mid-900 fps.
Power is measured in foot-pounds of energy (fpe) or joules. A .177 caliber BB gun will have enough power to possibly stick a BB into a 2×10 made of Douglas fir at 10 meters. A .50 caliber big bore air rifle will have enough power to put a .50 caliber pellet completely through the same 2×10 like it isn’t there and blow out a sizable exit hole on the backside of the 2×10 at 10 meters.
Lets put things in perspective. I know what you are thinking…. being this is a .44 Magnum, the most powerful handgun in the world; with a 340 grain slug traveling 1425 feet per second producing 1533 foot pounds of energy, it would blow you head clean off.
