I have one of the early big timber hartford 50-90ss guns with the wayy slow twist,
like 1 in 38",and of course when you use the Greenhill formula you will see you cannot properly stabilize a High coefficient spitzer boolit in it.
Those are like 6-700 grain slugs,and need a 1-24" .
300-450 grainers stabilize with it ,this I know,recoil is already boomin`.
but has any here tried those big mammas in the slow twist??
