[QUOTE="palerider3, post: 1747125, member: 82117"] Pick the bullet you want to shoot, 215-230 hybrids, 208-225 ELD-M have worked great for me, though I'm now shooting 230 ATips. I prefer RL-26 of H1000 with heavy bullets. Either way, pick a bullet and a powder and load a ladder to find pressure. Go a few grains past max and then just pull everything past your first sign of pressure. Load one at each charge weight from about the middle of the recommend loads and go up in .3 he increments. Shoot there through a chrono with the bullet seated .020" off the lands or so. Then find where the node is where the velocity spread between charge weights is lowest. Then load 5 at whatever is a common seating depth for that bullet. Shoot a group with that and see how it does. Maybe you'll have to load a few different seating depths if it's a bullet that you're not familiar with. That's the easiest way to develop a load. I can usually get a load with single digit SD, ES in the teens and half minute or better groups, in 30 rounds. I load develop for 4-7 new barrels per year and often a couple different bullets and rarely take more than 30-35 rounds to load develop. [/QUOTE]
