I spent the money for my 1st chronograph. Labradar. Always use it working up loads. Hornady book will show max fps on loads but then go shoot superformance ammo and this stuff exceeds anything in the book. I know, its Hornady's special powder not for sale. I will chono these rounds and try to get close, which is near impossible, but I don't exceed it. Will research the trace equipment just see understand a bit more. Popnfresh on ar15.com post some of that info also. Been debating on spending the money on quickload. Anything better?
