[QUOTE="Wild_Bill, post: 126949, member: 4785"] Hi all i have been thinking of making a sub sonic rifle for a few years and was looking at a 338 and then i had a thought why not use the 6.8SPC case it would push a 190+ gr .277 or 200gr .284 projectile over 1000fps with ease. I can get a 270 or 7mm blank in 8 twist so either should work i assume? The advantage with the 7mm over the 270 is that their are more heavy match projectiles available like the 180gr Berger. Wich way would you go? 7mm is my thought with a 17" barrel and mabe carbon wrapped. but the 6.8 is a factory chambering so their are advantages there aswell. Cheers Bill Australia [/QUOTE]
