I've got an SWFA 6x42 headed my way and I need to get a picatinny base. According to the specs plus everything I've read on the scope, it seems there is an plenty of elevation adjustment in the scope, something around 100 MOA. My question is, how far can I get WITHOUT a canted base? I'm shooting a 168gr match bullet at 2700fps in 308 Win. It seems like even with a 100 yard zero, this scope has enough elevation adjustment to take me out to 1000 yards.
