I would recommend slowing the powder down a step. H110 / W296 / 300MP are a better match but Lil Gun will get it done also. I've gone as high as 40.5gr 300MP with the Deepcurl / Gold Dots. They were seated short to catch the taper crimp in the cannelure. With a bolt gun, you can go a good deal longer at the price of not being able to crimp down into the cannelure but in a bolt gun, the rules are different. That longer COL would allow you to move up in charge past where I stopped in my AR.
