Go with an ARP 16" barrel. The melonite barrels in 16" will shoot as fast or better than an 18" stainless. With the right bullet and proper shot placement the deer won't know the difference.Okay guys - I am in the process of building another 6.8 SPC as a dedicated deer stand gun. Long story short, last year I built an AR10 for deer hunting and once it was completed, I realized it was just going to be too heavy to carry comfortably through the woods while on drives. Accordingly, I built a lightweight 6.8 (Thanks to the help of this forum) with a WC 16" lightweight profile barrel as my "woods pushing gun." I took two bucks last fall with the 6.8 and I liked the performance so much that I want to replace the AR10 in the deer stand with another 6.8 with greater magnification on my optic (My current 6.8 has a 1-4).
My questions is what are everyone's thoughts on the benefits of going from a 16" barrel to an 18" barrel? In northern MN and WI my longest shots in the woods are maybe 200 yards but occasionally I sit on a cornfield, where shots can be longer. I really like the short feel of the 16" and the weight but I am wondering if going the ballistic benefits of going to an 18" would be worth it. Thanks in advance.
