Does anyone have or heard of Mark Chanlynn barrels I have one coming but this is my first custom barrel and I'm new to all this custom stuff on a rifle I've been told go with a 7rum or a 7saum but from what I have read on here I maybe changing my mind on the caliber I go with the barrel will be a .284 and a 1-8 twist going on a stock remington sendora I will be putting a Jewell trigger in it other than that I have no clue what needs to be done to it want to shoot over 1000yrds and be able to hunt with it
