I never shot cmp so I was always using my own ammo. At club level matches, I never saw anyone who won High Power (and definitely never Palma) shooting anything but handloads.So you dont think it was just the ammo?
If you got free ammo, I suppose that might be motivation. Probably not for me, though. After seeing guys trying to clean rifles shot with scuzzy stuff (corrosive), no way. If it was the newer Greek stuff (hxp) maybe. Could I lie and show them a 1903 to get the free ammo then belt it up for a 1917 or 1919?
