I'm a faster twist guy, but 1 in 7" is pretty fast... even at 200 yards, too light a bullet can give you fits, until you get used to shooting in the wind... I have an older Contender barrel with a 1 in 14" twist, & it doesn't shoot even 55 grain bullets well... I've not seen a down side to faster twist rates than what is needed to stabilize a bullet ( maybe over the life of the barrel, it may be shortened a little with the faster twist ??? )... but again... most all target barrels 1st see wear at the throat, so the twist rate wouldn't have anything to do with troat wear...

my exprience shows a 1 in 9" twist should stabilize up to 68 grain bullets with even medium loads... so 1 in 7" should only be needed for bullets heavier than that...
