Hagen, if you use low pressure loads (known low pressure, not guessing), you can also use 2 3/4" hulls. Do you want to use 2 1/2" hulls for some reason? They are "bothersome" if you shoot much. Use the 2 3/4" loads that reloading manuals list as sub 7500 psi and you will be fine if the gun is up to shooting at all. Good choice on the 7/8 oz load as it does a lot to reduce recoil.
