Most if the 6.5x47 handload threads concentrate on grains of powder and velocity. I'm still working with my gunsmith to come up with the optimum throat length for the Lapua 123/139 and Berger 130 bullets. Many of you have suggested 0.109 freebore but I don't know what COAL and, more importantly, what ogive length you're loading to. For instance, from previous posts, I know Weda' is loading his 139 Scenar rounds @ 2.74" COAL and 2.136 ogive length. What I don't know is his freebore length. So I'd like to gather some data.
Please post
1) Bullet Make and weight
2) COAL
3) Ogive length
4) Freebore length
At the end, I'll compile this into a single table.
Thanks!
