[QUOTE="entoptics, post: 2248014, member: 104268"] Good question. Yes and no. The most recent iteration has been monitored for "hot as hell", but it isn't much different from spring's work. I did a sensitivity test ([URL='https://www.longrangehunting.com/threads/temperature-sensitivity-test-imr-8133-and-reloder-26.256831/']click here for thread, H1000 on 2nd page[/URL]), and though my H1000 results were a little more sensitive than some, I am not too worried. I collect LabRadar data on 90% of my shots, and if there is a velocity change on a particular batch, I either adjust my software accordingly, or if I'm concerned about pressure (or lack there of), I ± a tenth or three and call it good. This load, at 3055 fps is at the upper end of my comfort zone. Barest hint of bolt stiffness, but primers are still well rounded, and no ejector marks. I checked the primer pockets on a few brass after 2nd firing, and they're still good, but I wouldn't be surprised if they start to loosen up after the third firing. For comparison, I got 3060 fps in March at about 60° F with the same recipe. [/QUOTE]
