[QUOTE="Black Diamond 408, post: 360871, member: 1563"] Kelly, I have built two 375's for my personal use, the first one was to test a McGowan 12 twist barrel. It shot the 350,s great, but the longer bullets were not so stable. My second rifle has the Gain Twist experiment, i wanted to move into the higher BC bullets that are coming out, remember the standard twist for the cheytac is 11.5 and that shoots the Hookers good and they are a high BC of .945 plus the SMKs at .770 I do a lot of R and D here with barrels and twists and new wildcats, some work some dont. I have tried most twist rates but when you start dealing in the extreme BC bullets your going to be stuck with one bullet type or make. Long range ... well the SMK has enough energy to kill an Elk past 2400yds, the 370gn RockyMtn will have even more and these are legal hunting bullets. So in my opinon if your building a rifle your going to hunt with then get a barrel that will handle these bullets. If you push these bullets to 3200fps and over spin them you will see poor results. It takes quite a while to get a gain twist barrel from Bartlien. I would like to try a Gain twist in somthing like 20 to 10 exit, Just for the Jacketed bullets. [/QUOTE]
