Great Britain has come in #1 or #2 in the Palma matches every match since 1985. In that same time frame the US has come in #1 once, #2 twice, and 3rd place once. The US failed to make top three at 4 different Palma matches where the Brits have never settled for third place or lower.
Of course the Brits were shooting ball ammo in 1992, but Radway Green always put aside the first lot after new dies are installed for "sniper" and "match" lots.
Machine guns are awesome until you have to carry one.
