Well another lovely day and a sneaky range visit. And was looking at the speed, and had this question pop up. I need to get the actual data, but it's 2800 fps in a 308 shooting a 155gr profile hopping along to fast to kill my barrel? Or 27xx pushing a 168gr projectile. With these high speeds the sd was under 10 and es ws really good as well. Grouping was quite good. But then I ran a mystery reload (a mate did up for me) with what I think is sierra matchking tipped projectiles and at 25xx fps they were really good grouping.
I am just worried I'll burn my barrel rather quickly at these speeds. What do ppl think
Actually I was shoting the 155s faster than the 140gr 6.5 manbun. Btw in need to look at the ppu brass.
