Types and methods of barrel rifling

[mongoosesnipe]

I have heard the 5r is supposed to foul less but good barrels usually don't have fouling issues hammer forged and cut are supposed to be a little more durable than button cut is touted as being more consistant but if you go with a high end barrel it will more than likely out shoot your abilities and barrel wear shouldn't be a significant issue with the Grendel it operate at a relitivly low pressure with small charges so its not overbored so all the rifling type Should have a good long life
