[QUOTE="Broz, post: 636925, member: 7503"] The big thing these days is power lots. They vary up to 4 gr in a 338 LM with a 300 bullet. So I think your plan is good. 85gr is on the low end, but will be safe. Then as you get towards 89 gr start to watch closely. I have seen ejector marks show up as early as 90. But most 338 lms with 300's get to 91 and some to 92.5 like mine. Any load with a 300 gr bullet at 93 gr was hot in every 338 LM I have worked with. So you can see how a powder lot 3 to 4 gr hotter will be so important and rifle / powder lot specific while developing loads. All my data is from Lapua head stamp brass. I doubt any other headstamp will get to these levels before pressure shows up with ejector pin shadows. Jeff [/QUOTE]
