My comment here may not be very popular, but these FX air rifles are very well optimized at the factory. Seriously, they are very well tested in Sweden and again tested at the importer. They pretty much shoot MOA or better at 100 yds. as delivered. Velocity and pellet weight are simply parameters to the end goal of hitting your target. The Crown in 25 with the new X barrel was designed and tuned around the JSB 25.39 grain pellet. If you are not hitting your target, I suggest you practice more and tune yourself not your Crown. It could prevent a seriously expensive repair bill at the importer. These rifles are surprisingly delicate and if you don't know what your doing, serious damage can result. There is a great deal to optimizing a rifle for a heavier pellet many of those parameters are with the barrel twist and choke that you, as the turner have no control over..
