[QUOTE="Jud96, post: 2526047, member: 69478"] To me 40.9 looks to be a good place to be. I would definitely do seating depth testing there. Also, the 41.5gr load might be the start of another node. You can further test 41.5-42.5 and see if there’s anything in there that’s promising. Just keep an eye out for pressure signs as you work up. I like to start .010 off the lands and work back in .005 increments. I typically will test .010-.050 off. I look for 2-3 loads in a row with good groups and load to the shortest of the 2/3 and call that good. I shoot 2 shot groups and again look for a window where I’m getting the bullets touching or dang close for 2-3 depths and with similar points of impact. You’ll have some ugly ones but that’s the point of the test. You can do 3-5 shot groups to get a better idea, but I like to conserve components and 2 shots gives me a good idea. I’ll then go back and test 3-5 shot groups to confirm the precision of the load. Below is an example of a seating depth test I shot. The orange target is me verifying the load and the zero. There’s 5 shots in the top group and then 3 in the center. These were seated .010 off the lands which was the start of my seating depth node as you can see.
