I don't have it in front of me, but I believe the Lyman 49th Edition puts the max at 27.1 for Varget. The Hogdon/IMR/Winchester site puts it at 27.5gr.
At 26.5, I get just the faintest signs of beginnings of flattened primers (looks just like the factory load primers after firing). I would not go above that with the components I use. The Privi Partizan brass is right up there in weight with Lake City, and a tenth or two of a grain heavier on average than Winchester brass- so it's my thinking that I'm stuffing it iinto a smaller space. I tend to think that with Remington or Federal/FC brass- the beginnings of those flat primers might not be so evident.

I'm going to use the words "clip" and "Long Colt" every chance I get. It grinds my gears to see new members attacked when we all know dang good and well what's being refered to.
