Evening all . I have recently bought an old bsa .270 for Scotland . I wanted a flat shooting rifle as when we were up there in January we were shooting at 200 yards plus .
I have finally got round to zeroing it today . It shot great with Norma and ppu in 130 grain .
However with cold barrel at 100 yards and 200 yards it shot low by 2 inches and 4 inches respectably at those distances . But the next two shots through a warm barrel were spot on !
So as we are shooting hinds and multiple shots will be taken where do I set the zero and is this normal .
The barrel and moderator after three shots got very warm !!! I haven't, had a .270 before .
