As you might expect the most frequent topics on airgun forums are the features and foibles of the dozens and lots of different models, but following closely behind the model discussions may be the chatter about airgun ammunition or pellets. May very well not expect that a.177 caliber pellet from Manufacturer A would perform wildly different from a.177 caliber pellet from Manufacturer B in the exact same airgun, however they do. To make it even harder Manufacturer B’s ammo may outperform Manufacturer A’s in a different air rifle or pistol.
We will discuss a few of the different characteristics of airgun pellets and how you need to use these details to your advantage when selecting a pellet for the air rifle or pistol.
A light pellet will leave the barrel of an airgun faster than the usual heavier pellet and it will also accelerate faster downrange 30-30 ammo. That means less time to focus on and a flatter trajectory while there is less time for gravity to work its magic. A weightier pellet will are apt to have a less flat trajectory not due to its weight but because it spends additional time to focus on providing gravity with increased time to pull it towards the earth.
The 2nd factor that a lot of affects the flight of an airgun pellet is air resistance. Air resistance increases with the cube of speed. Whenever 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 if a 35 yd. approximately it is likely to be moving slower than the usual heavier pellet fired from the exact same gun. Air resistance might be irrelevant for target shooting out to 10 m but it would play a large role in a hunting shot beyond that range. That is among the reasons that you want to hunt with the heaviest pellet your airgun are designed for effectively.
As well as the weight of the pellet air resistance will vary according to the shape of the pellet. Wadcutters are flat nose pellets employed for paper target shooting. At the 10 m range the escalation in air resistance is almost negligible but the same as with the aftereffect of weight beyond 35 yd. the flat nose begins working as an air brake.
Medium weight round nose pellets offer the best compromise for both weight and shape for medium powered air rifles. For small caliber air rifles (.177 and.20) the best hunting ammo is a circular nose hollowpoint. This pellet moves through the air in addition to a typical round nose and mushrooms on impact significantly increasing the force of the shot.
The best advice about air rifle ammo is to try many different brands, many different shapes, and many different weights. Everything you read within the airgun forums may be true generally but might not work for your air rifle. If you should be only a periodic shooter and still want the best accuracy and range then pick a premium pellet from the exact same manufacturer that made your gun. It is almost always best in order to avoid no-name bargains because there could be significant variability between pellets in the exact same package.
