Re: Hodgdon CFE 223
Biggin,
I need to do this delicately. After all, this is Mr Litz's ammo i'm talking about.
The ammo you reference is desinged for commercial consumption. This means that in order to make sure it functions well in many different rifles without going kaboom & injuring people, it is loaded to relatively mild velocities calculated to be accurate in many rifles...think 308 FGMM.
175FGMM is a "slow" round. It is very accurate in many rifles, and is mild enough that nobody reports any issues with too high a pressure.
Hornady tried to turn that convention on its head with its line of Superformance ammunition with mixed results. The superformance ammo fufills its marketing hype in many rifles, but shows signs of pressure in others.
In the final analysis, if your new load allows you to do what you want, then that's fine. But if you intend to shoot 1,000yards accurately, i think you'll find that wind-drift will kill you since you are launching your projectile so slowly.
Visit Dan NewBerry's website on OCW for a more indepth analysis of what informs my view of reloading.
