Depends on what for, the cartridge and the load IMHO. If you are shooting at the min powder and fairly short range ie under 300m and say a 308winchester I doubt you would notice the difference frankly. For instance Ive shot Winchester, S&B and then 1943 brass in batches of 10~12 with the same load (38gr 2208) in the same 303 Enfield at 300m and didnt see any difference in height/drop, even at 500yds at target shooting. So for hunting?
I'd expect Federal to be thinner (the thinnest?) and hence a wee bit slower than the Norma. Im hoping the NI crony will become available shortly and I will do some testing with the above plus some privy.
