Response to Dan, its not really that simple although, i would love to
By retuning the air passages, we made over 320 fpe with a .308. We just couldn't use the same internals as the Ranger.45. Next year we'll be making a .308/.357 rifle called the Scout. It won't look different, but will built for those bullets sizes.
Bullet speed is dictated by a couple laws of physics. Pressure on an affected area and the speed air moves at a given pressure and lastly, the speed the air loses as it travels in a pipe. Bigger air ports move more air than small ones, but just more air doesn't make faster bullets.
Basically, we can get the same velocity with any caliber, but then you have to balance the weight of the bullet with the pressure and air flow to maximize velocity. Even though you can make really heavy bullets fly fast enough for big fpe, the reality is, its not a good hunting round.
The ability to shoot a wide range of bullet weights, with a wide range of pressures, is what we do.
