[QUOTE="Deleted member 46119, post: 1063449"] I got my MagnetoSpeed back and with a change of batteries my Pressure Trace II stopped acting up. Today I was able to finish the 308/26-Nosler Berger test and the .277 165 VLD Matrix. There are 16 pages of data to transcribe to the various threads but I know many are interested in certain bullets. Reminder these test barrels are all 24". 338 Barnes 280 LRX made it to ~2780fps at an indicated 64k psi and the case looked like it was that hot. The COAL was conservative. I could get a lot more capacity if I stretched out the COAL. The CEB 252 MTH is a much better match to the Nosler cartridge dimensions. That one goes ~2900fps from a 24" barrel at only 55k psi. 308 Berger 230 Hybrid topped out at ~2950fps at 56k psi. It can go faster. 284 Matrix 190 VLD went ~3050fps at 63k psi before the chron succumbed to the bombardment of the muzzle blast. Kudos to MagnetoSpeed for incredible service. 277 Matrix 165 VLD went ~3200fps at 63k psi before I stopped with 3 loads left that I would not shoot in a Reminton 700. I'd shoot those pressures in a Weatherby buy not an R700. [/QUOTE]
