[QUOTE="Shortmagman, post: 399027, member: 10723"] I have loaded my Ruger 77 Mark II in 7mm Rem mag for a number of years. I have used many different powder and have been able to get both accuracy and good speed shooting 160 grain Nosler Accubond bullets. My gun has a long throat so it take a little more powder that many manuals list to achieve the stated velocity. My current favorite load with the 160 Accubond uses RP case, WLRM primers, and 67.0 grains of RL-22. I know this is over most published data.It is safe and very effective in my gun. It may not be in your gun! However, if I were you I would increase my powder charge. Work up slowly and watch for signs of pressure. I just looked at the Alliant data and they show 65.0 grains of RL-22, and a 160 Grain Speer SP bullet for 2900+ ft/sec.. My 67 grains with the 160 Accubonds give 2950 ft/sec.. I have also used H1000 with the 160 Accubonds and with 70-72 grains I have gotten 2950+ ft/sec. This is also a very good load in my gun. If I were loading 61.0 grains of RL-22 in my gun I would be getting close to the same velocity as you are getting. [/QUOTE]
