.308 .168 free bore? 10 twist

[josebd]

Can you still shoot sierra 168-175 matchking bullets? What would be tha maximum bullet weight for 10 twist?

You can still shoot them... they'll just be jumping - a lot.

Bullet length is more the determining factor than weight. Usually they are closely correlated to where people conflate the effect. But if you run the appropriate numbers for say, Berger 200.20X's vs Sierra 200 MK's, you'll see what I mean.

10 will stabilize really long bullets. You could do 178 ELDMs loaded pretty long.

I got a .168 freebore in my 1/10 twist for shooting heavy 308 bullets. I'm getting .300 groups at 100 & .450 at 300 with 185 Juggernauts at .025 jump.
Strange, but this load shoots better for me than the 200gr bullets.
