I not found alot on this yet, maybe you folks could help me out (or talk me out of it!!)
I have heard that my standard 257wby can augered out to a 257stw or a 257-300wby(?) and using ultraslow powders (that were unavailable in Roy weatherbys day).
apparently these will create some OUTRAGEOUS velocitys and remain within reasonable pressure (100grains at 4200+fps)
