guessing your rifle has a long throat/lead ..... each rifle is different and will handle different pressures,mine is happy a couple of grains above book max but I ve worked up to that carefully over a lot of years...definately check load in warmer weather with caution. if you getting same/similar speed to superpreformance you can pretty much say your pressure is getting up there as those loads are close to edge of envelope...eg a lot of guys cant macth speed with reload and SOME rifles show excess pressure with them.
