[QUOTE="Remi, post: 5627845, member: 21887"] My stuff runs about 1-1.5grs different on regular vs magnum sparklers. A chrono would be the only real way to see where you are at for velocity, es, sd, etc As for flattened primers, I wouldn't put much into that. If you are oversizing your brass and creating excess headspace you will see flattened primers. Primers in general are not a good way to read pressure. Flat primers can come from excess headpsace, cratered primers can come from excess space in the firing pin hole on the bolt. Primal rights has a great article on why primers aren't a great way to read pressure. I would post a link but every time I post a link my posts are set to invisible for moderator review. The article is Understanding Pressure [/QUOTE]
