I shot my 14th whitetail doe last night with the 107 gr 6mm SMK. The reason I bring this up is the 6mm gets a lot of mileage here and I've had great luck with these bullets inside 500 yards. All bang flops with massive internal trauma and pieces of lead everywhere. These are going 3200 fps in my 6x284 and I've killed deer as far as 1007 yards. Once you get over 500 yards or it looks like you get under 2300 fps you start getting pencil holes all the way through and very poor bullet performance so I don't shoot that far anymore. Also, button bucks can be hard to tell way out there. I just thought somebody might be interested in these results. On a side note, the reason I still shoot these bullets is because it's the only bullet my 6x284 will consistently shoot under 3/4 of an inch. The 105 gr A-Max was great but blew up and everything else won't shoot. It's been frustrating using up a lot of barrel life to find nothing and the 107 shoots by far the best with H4350 so I get pressure at even 3200 fps.
