In planning a 338 Win Mag rebore I was asked the question of how many grooves, 3, 4 or 5 - I don't have a clue - I believe 4 grooves is the norm but I've seen a high dollar custom rifle maker brag up their 5 groove bores - Does anyone have any suggestions or reasoning on this topic ? barrel length will be 24"
