[QUOTE="zoeper, post: 322923, member: 10682"] L+L, I've heard of bullets going up into a puff of dust as soon as it leaves the barrel. I also know a guy who shoots the 6mm nosler bt 55grainers @4250 from a 1 in 8" twist barrel on a stock standard .243 Win without any problems. I do however beleive that the extra twist puts a lot of strain on the bullet's forward acceleration that is probably a good thing for such a light bullet. It could even save you a grain or two of powder by holding it back while presure builds?? Fo myself i have decided on a 28" Broughton 5C 1/10" twist for the 80-90grain bullets. This should be a good compromise between fast/ flat while still retaining some BC to buck the wind and maintaining a little more energy for the slightly longer shots. What is the life expectancy of your barrel while shooting the 107's at 3800?? Thank you for your input [/QUOTE]
