So I'm thinking about building my first semi custom. What I'm thinking is a tikka action. And one of two barrels depending on what caliber I choose. If I go with 6.5 creedmoor I would get a 26 inch 7.5 twist one barrel. If I go with the 6.5sst I would go with a 26" 7.5 twist preferred barrel blanks. And also caliber dependent, the manners mcs-prs1tk or the krg bravo. I'm thinking if I go with the 6.5 creedmoor I'm almost going to have to get the manners because, with the longer bullets and the creed case, I won't be able to seat them where they should be seated and feed from an aics mag that the bravo takes. Which is why if I went with the sst, I could get the bravo because the oal on the Sherman is so much shorter and will feed from anything. Am I right in my thinking? Or are there other options for magazines besides the 2.860" short action aics mags that will work with the bravo? The loss in velocity by going with the creedmoor vs the sst does not bother me since this is just a practice rifle. If anything, less velocity will make me a better shooter by forcing me to be more accurate with my wind calls. Another thing I'm thinking is that eventually when I try my hand at prs, I would use this rifle. Any info or other ideas would be great! Thanks guys. Can't wait to hear from people way more experienced than me!
