As you may expect the most typical topics on airgun forums are the features and foibles of the dozens and dozens of different models, but following closely behind the model discussions is the chatter about airgun ammunition or pellets. You may not expect that a.177 caliber pellet from Manufacturer A would perform wildly different from a.177 caliber pellet from Manufacturer B in exactly the same airgun, nevertheless they do. To make it even harder Manufacturer B’s ammo may outperform Manufacturer A’s in an alternative air rifle or pistol.
We will discuss some of the different characteristics of airgun pellets and how you need to use this information to your advantage when selecting a pellet for the air rifle or pistol.
A lighter pellet will leave the barrel of an airgun faster than a heavier pellet and it will even accelerate faster downrange best place to buy ammo online. Which means less time to a target and a flatter trajectory because there is less time for gravity to work its magic. A weightier pellet will are apt to have a less flat trajectory not because of its weight but because it spends more hours to a target providing gravity with more time to pull it towards the earth.
The second factor that most affects the flight of an airgun pellet is air resistance. Air resistance increases with the cube of speed. When you double the speed of a pellet moving downrange you increase its air resistance by eight times. Really light.177 caliber pellets lose energy because of air resistance so rapidly that after a 35 yd. or so it is likely to be moving slower than a heavier pellet fired from exactly the same gun. Air resistance is probably irrelevant for target shooting out to 10 m but it would play a large role in a hunting shot beyond that range. That is one of the reasons that you wish to hunt with the heaviest pellet your airgun can handle effectively.
As well as the weight of the pellet air resistance will vary according to the model of the pellet. Wadcutters are flat nose pellets useful for paper target shooting. At the 10 m range the escalation in air resistance is practically negligible but exactly like with the aftereffect of weight beyond 35 yd. the flat nose will become working as an air brake.
Medium weight round nose pellets offer the very best compromise for both weight and shape for medium powered air rifles. For small caliber air rifles (.177 and.20) the very best hunting ammo is a circular nose hollowpoint. This pellet moves through the air as well as a typical round nose and mushrooms on impact significantly increasing the force of the shot.
The most effective advice about air rifle ammo is to test several different brands, several different shapes, and several different weights. What you read inside the airgun forums might be true generally but may not work for your air rifle. If you should be only an occasional shooter and still want the very best accuracy and range then pick a premium pellet from exactly the same manufacturer that made your gun. It is more often than not best in order to avoid no-name bargains because there might be significant variability between pellets in exactly the same package.
