168 grain TTSX help needed for my .300 Winny

[csquared76]

Okay, I am hoping to reap from the collective wisdom and experience of fellow gunnutterz. Due to recent powder shortages, I have had to abandon my favorite load for now. I managed to score 4 pounds of N560 now, and am going to try working up a load for the 168 grain TTSX. Has anybody used this combo? If so, what were your starting and accu4acy loads? I haven't seen this combo listed in any manual I've looked at. Maybe that should tell me something. .. Want to try it anyway. The burn rate should be in the ball park. Vihtavourhi shows it somewhere between RL19 and RL22.

Well, for anybody interested, I worked up some loads from 71 grains to 79 grains of N560. I started seeing pressure at 78 grains. 79 was over max in my rifle. Typical of my gun, the harder I pushed it the tighter the groups got. I got sub moa groupings at 75 and 77 grains. 79 was hot enough that I didn't shoot them all. Chronograph data to come next as I play with the 75 and 77 grain nodes a little and see what they will do. Does anybody have a copy of Quickload that would run the numbers for me? Winchester cases trimmed to 2.610, Fed 215M primers, OAL 3.46. Thanks!
