[QUOTE="dhbikerczar, post: 2561029, member: 113757"] Customer here…. I did initial ladder test looking for pressure. I ran from 90g to 94.5g in some Lapua brass I had. The Lapua brass has been abused under 215 HH loads. 94 and 94.5 were the first two that shows any sign of flattening the primers. No catering and no ejector marks yet (with this soft a Lapua brass, that’s a surprise). The step in velocity between 94g and 94.5 was about 1/2 the steep size of other 0.5gr steps. Idk of I got to the point that not all the powder was burning or if I was just hitting a wide node. More validation to come. The last shot clocked at 3477 FPS. As always, do not use this load data, this is for my custom improved chamber and custom action etc. this is strictly information based on my setup. [/QUOTE]
