Thread: 2208 vs 2206h for .308

Ahhhh - I've got the answer, you need to be using H4895. Your rifle is label-fussy!

The other option you can try although at the moment it's bloody hard - is a primer swap. Primers can have quite an effect on the initial pressure curve and bullet initial upset into the leade or throat of the rifling, and this can produce some quite weird results in terms of pressure and accuracy.
