So if I limit myself to 600 should I go 1/10 an light bullets or 1/8 and heavy. Of course wind is my biggest killers. Note, my targets were shot in low wind. If it had been windy it would be ugly.
Like others have said, go with the 1/8. I have a Dasher with a 1/8 and 104 freebore. I have shot primarily 105 Berger VLD's. I recently tried some lighter 80 Bergers and got a pleasant surprise. The 80's will make it to the lands with plenty of the bullet still in the case neck. And they shoot very small with a stiff load of Varget at about 3380 fps.
All that to say don't be afraid to try lighter bullets in a 1/8 twist in a BR.
