don't know witch way to go i have both right now but the one I'm shooting now is 243. I don't have a lot of brass or bullets for the 243 but i do have a lot for the 260 the 243 is going to fast for some matches shooting steel (factory 1in 9.125 95gr bergers) but paper I'm good. So going to change the barrel to a faster twist 243 or go with the 260 that i have lots of brass and bullets and wanted to see what everyone thinks.
 
IIWM I'd go 260. Of course, I did. I have 243s as well.

Assuming an 8tw 140grns or a little more. 130grns if a 9tw.

If you rebarrel the 243 I recommend an 8tw or even 7.75.

Been there, done that. More please.
 
260 is the way I was leaning but I thought I would ask and see what everyone thought and hear what other shooters had to say. thanks
