[QUOTE="amu_shooter, post: 255933, member: 12411"] I'm in the early stages of testing a 338/375 Ruger. Weapon is an unmodified Sendero in 300WM rebarreled with a 27 inch, 1-9.0 twist, 1.250-.825 taper Satern barrel. Here is a current list of data fired, I'll update every few days as I shoot. All initial 225 Accubond loads use 215M primers and OAL set at 3.510 to use magazine. [B][U]nosler 225 accubond[/U][/B] RL-22, 85.5gr, 3146 fps [B](close to max in my weapon[/B]) IMR 7828, 83.5gr, 3067 fps (low pressure compared to RL22 load) H4831SC, 82.5gr, 3021 fps (primers slightly flat) Still have Hybrid100V and few others to test. [B][U]300 sierra matchking [/U][/B]OAL changed to 3.650, still 215M primer IMR 7828, 75.0gr, 2623 fps (initial 300 gr load, would like to make 2700 fps before overpressure) I've used BR-2 primers with similar charges under 90gr in similar cases so I'll try those next along with 250 AB's and MK's.
