It is worth noting that in the world of airguns, ammunition (slugs, bullets) and calibers are decoupled from the power produced by the gun. With this benchmark both the AirForce and Hatsan shared the most powerful moniker for a while. So, to provide context, I always look at peak power in an out-of-the-box configuration.

But all things considered, once you have achieved a level of accuracy and come up with a design that works for shooters, more power is usually better. The benchmark for the most powerful air rifles is power output, which makes sense, even though I firmly believe that accuracy trumps this and shootability is close on its heels. Concurrent with this, other manufacturing companies started to gain traction, some small-scale startups such as Professional Big Bore Airguns (PBBA), and other large-scale manufacturers such as Hatsan Airguns, offered a large and evolving lineup of powerful big bore rifles. The American airgun manufacturing giant Crosman and later the smaller, more experienced PCP air rifle manufacturer AirForce Airguns, released true big-bore air rifles to the US market. Then, a couple of important events occurred over a few short years. Yet, they tended to be somewhat anemic in comparison to a Quackenbush of the era. ![]() It is true that there were a couple of major overseas manufacturers producing a limited selection of big bores.

Then, later that year, he built another rifle in. ![]() 308 semi-custom rifle built for me by the father of the modern big bore airgun, Dennis Quackenbush. I started my big bore airgunning journey back in 2002 with a. ![]()
