Powder is ADI 2208. I can't switch away from ADI as it is specified in the rule book for my preferred class here. It is equivalent to Varget and IMR4064. Pretty sure one of those two is exactly same powder just repackaged anyway. One of your powders is Australian made !

I've taken a look at the bedding and as suggested by the more experienced shooters here and have taken a high spot off well in front of lug and also relieved clamping by the bedding compound forward and below lug. It will be next Sunday before I can test results.

Scope is Leupold V-XIII 6.5-20x50 but I've also tried a Weaver 36x40 brand new out of box.
