So I'm loading for my 7mm08 and using 165 gr. Sierra Game Changer and there isn't much load data available. I have some data from Sierra , but it doesn't give the powder I am wanting to load(Imr8208xbr).
Hogdon lists the 162 gr, A-max with this powder and a Coal of 2.875". My Tikka being a long action can handle up to 2.988" to the lands.
My question is what is your process for making the jump from a published Coal to the longer length of say 2.96" or about 20 or 30 thou off?
I've loaded up some with a Coal of 2.875" and they shot fine ie no pressure signs yet. I'm still below the published max for the 162 gr. A-max with velocity only 2575fps. How big of a jump in length can I go, if I load the last load I have tested, say 2.9" then 2.925"? Is 25 thou too big of a jump when incrementing ?
