Well got my barreled action in today, bolted it in my Mcmillan stock and topped it off with a 1-4 nightforce scope. I started with 86.0 grains and finished with 92.0 grains of H414. Here is the data.
38ºF, 28.8"Hg, Alt 250'
86.0 2348, 2436, 2371 SD45
87.0 2463, 2414, 2414 SD28
88.0 2458, 2395, 2414 SD32
89.0 2464, 2505, 2496 SD21
90.0 2449, 2477, 2488 SD20 Recoil stout now pressure still low.
91.0 error, 2501, 2526 SD17 Recoil stout still low pressure
92.0 2547, 2535 SD8
Primers are looking good, no pressure signs, and bolt opens like butter. I will load a couple more at 93.0 and 94.0 and shoot them tomorrow to see if I can hit 2600 before I pressure out. The 92.0 grain load looks good and should be safe in warmer weather also, but just want to see what the rifle will do with a stouter charge. I cleaned the barrel after 88 grains and it took six rounds to settle back down. 91-92 tightened back up. I still need to get used to shooting a 4 power scope I am spoiled with my 30 power on my 300 RUM. Here's the target and some brass (91-92 grains).
