A lot of your question depends on the load you are going to use. If its a hot load already you may be well overpressured. If its a warm load it will then be in the hot category. If it is a mild load you are shooting it is probably ok. So much depends on powder type, bullet weight, case volume, bullet design, chamber dimensions, bore diameter, etc. All of these things are intermixed in determining pressure that it is difficult to say how much difference a hotter primer will make. It will make some for sure. I would choose a light load and try a few it they are ok then go from there.
