[QUOTE="MagnumManiac, post: 1456507, member: 10755"] The number of grooves increases or decreases the friction applied to the bullet. Interesting fact, I have custom chambered hunting rifles with 4 grooves, factory hunting rifles with 6 grooves and 4 grooves and custom comp guns with 3 or 4 grooves. Only one 5R so far. Every one decreases in velocity in comparable barrel length as groove number increases. It takes less powder to reach the same velocities in the 3 groove barrels. It’s also far easier to clean, but that may just be because the 3 groove barrels are custom cut rifled barrels. The factory barrels are all button rifled/hammer forged as far as I am aware. Cheers. :confused: [/QUOTE]
