Not my biggest buck ever, but the first with the M&P 10. 230 yards and dropped like a rock. I also got two does on the same hunt with it, they took a combined total of zero steps!
Yeah, I am liking the 308. My brother borrowed the rifle for the middle weekend and got a buck and three does, none took a step. I was a little skeptical about an AR- 10 style rifle, but am now a firm believer; light weight, accurate, and hard hitting.
