[QUOTE="300win, post: 113766, member: 5965"] I agree the twist rate is more important than how many grooves. Saying that I do prefer the 3 and 4 groove .30 cal barrels from Lilja.They shoot great and if there is one advantage it may be a longer barrel life because of less erosion on the rifle lead or so they say. It is also said that the wider lands will foul less than the narrow ones because ther is half as many edges on a three groove as a six groove. On most high Quality barrels fouling is not an issue but if you are shooting all day in a dog town or competition it may be an advantage. [/QUOTE]
