[QUOTE="Seabeeken, post: 2177140, member: 68015"] Mike, I talked to Don at accurate powders some months ago about temperature sensitivity and he told me that it is a relative thing. One maker's definition is different from another. I also asked about the Ramshot line sensitivity and I was amazed at how little temp affected it since it is a ball powder. Any time we push loads to the upper limits we run the risk of overpressure in hot temps so its best to develop these loads in the hottest temps we are likely to shoot in. A few years ago while working up a load in my 243ai, I tried some H-414 and got some crazy results. One load would show a normal load and then the next would show high pressure and the next low again. Its a great powder in some cartridges but in that case it was way too unpredictable and I haven't messed with it since. [/QUOTE]
