[QUOTE="Lefty7mmstw, post: 899476, member: 48043"] I've got a 24" bbl on my currest stw. My dad has the dmb rem with a 25" bbl. My sendero had a 26" bbl. None seem to really make much difference over the chrono.

I was using. You will get fps gain by going longer than 24", but it won't be over 20-25 fps per inch. I'll stay in the 24-26" range on my big 7mm's. [/QUOTE]
