How much is the runout affecting your groups?
I haven't worried about it before, but if a makes a noticeable difference, I might start.
As I say, some guns, like a 7mm08 I have, you can shoot rocks sideways thru it and get subMOA. But others like my 300RUM or ones with alot of freebore, it seems to affect it alot. I did alot of testing where I separated out my bad with my excellent. It made a different from going from .5MOA to 1.5MOA. Thats considerable.
I usually see it affect guys who say, "I found a great load was getting .5" groups at 100 yards the other day, but now, I am all other the place". I go over to thier ammo, and roll it, and watch it wobble like nobodies business. Is that the reason? Who knows, but I know when I take it out of the equation, its not a problem anymore.
I love reloading and learning new things. And love striving to make the best ammo I can. I know I am very particular. but its my hobby, and I love it.
I say for anyone who has been struggling to get loads working they shoot great one day and bad another, take a look at it.
