Hi guys...this is a real beginners question.

I'm trying to work up a load with the 162 Amax and ADI 2209 for my Stevens 7mm 08. The 2209 gives me good velocity but really doesn't fit. Rather than go to a faster powder such as 2208 (Varget) can I safely wind the barrel out to increase the headspace a couple of mm.

Cheers...Chris
