[QUOTE="sinarms, post: 519854, member: 27649"] Shot the 338 Sin today, figured out that my rings were a little loose, groups tightened to under 3/4" once I figured that out. Used some R19 with 250gr SMK bullets. I worked up to just under 3050fps. I would say that is pretty much max with that powder as groups opened a little. At around 2950-2975fps I was shooting right around 1/2" groups. Low ES of 7-15fps on most loads I tried. As Don stated this is pretty easy to get a load for. Dump powder in and load bullet and you can pretty much shoot 1" or under. I plan on shooting some 300smks later this week. More to come. [/QUOTE]
