[QUOTE="Buster Hemlock, post: 1660645, member: 109327"] Not all powders used in factory ammo is blended, plenty is loaded with the same stuff you and I can buy on the shelf. As far as velocity, myself and many others get velocities well above published speeds, without pushing pressure. This has been confirmed using Piezo strain gauges. Reloading manuals are a good starting point, but are conservative. Test barrels are typically cut to absolute minimum spec and because of this pressure up sooner than what our barrels on manufactured or custom rifles do as the chambers, Leads and throats are more generous. I know of multiple test barrels that had to be sent back because they were so tight they couldn't even chamber a round. [/QUOTE]
