[QUOTE="Oliveralan, post: 362240, member: 20245"] Speer said 61grs, hodgden said max 62.5 so 61 sounds like a good place to start. Load 2 or 3 rounds at .3gr intervals from 61 to 66ish then shoot a ton of groups but make sure the barrel cools and shoot some foulers first. Your groups will open up, tighten, then open up and maybe tighten again. Then pick the tighest group that gives the highest velocity (say 61.3grs gives a .4" group and 64.2gr gives a .35" group, go with the higher load). After this you can tinker with COAL length/ seating depth. I'm not too familiar with the specific bullets you listed but I think seating them between 20 thou and touching that lands would be a good starting point for your load work up. Once you found an accuracy node, load 2-3bullets at 5thousandth intervals from 30thou off to 5thou jammed in the lands (unless your shooting a hot load, this will increase pressure) once you've done that, you'll have a custom load tailored to your rifle.
