[QUOTE="kfd518, post: 2784335, member: 125515"] So I previously worked up a 300 win mag for load with ramshot hunter pushing 180 AB with Winchester brass and cci 34’s to 3050 on average with 70.5 gr. I know this powder is between 4350 and 4831 in burn rate. While developing that load it increased as expected with charge increases. Working with same components and changing to H1000 from 78.5-80.5 gr I got the following numbers, 78.5 3037, 2901, 2879 2866 79 2867, 2895, 2880, 2862, 2879 79.5 2914, 2884, 2879, 2888, 2889 80 2900, 2896, 2909, 2892, 2888 80.5 2977, 2975, 2983, 2986, 2962 Even ignoring those at the ES limits The rate of rise seems inconsequential and weird until it his 80.5 All cases were sized 0.002” bump. And increased by the same amount after firing. All ogives were seated within 0.001 of each other and verified prior to firing. Does anyone have any thoughts concerning the close to static velocity through 1.5 hrs charge weight? Is this just a node? Didn’t have anything like this with hunter powder and have never seen something like these numbers before. [/QUOTE]
