What brass are you running? The case volume between the Lapua, Rem and Winchester (7-08 necked down) will have a big influence. And what is your COAL?

If it's a time proven load in your rifle, I'd run it. That's assuming you've shot this load in the heat. If you worked it up last December, tread lightly. I'm not sure of the temp sensitivity of that powder, but if you haven't tested it throughout all conditions I would be aware of the possibility that hot load may become dangerous in the heat.

Im at 2.780" coal As always, work up to that load, or any over max load. Don't just start there knowing that it's an over max load already, if you have never tried it. Back off a few grains and slowly work up to it. When I work up a load for a rifle, I back off a little from max, and work up to max, or slightly over max. If it's a customers' rifle, then I'll have 3-5 rounds of different test groups to shoot working up to max. If it's my personal rifle and I don't have any known data yet, I may load up 1 round at a time and shoot it to find max pressure. Once I find it, I know not to go over this, and work below that powder charge. If there's no pressure signs, then it should be fine. The main pressure signs I look for are sticky bolt lift and extractor marks on the case head.
