5. If you’re not worried about a 3 degree F change in powder temperature, don’t worry about a tenth of a grain of powder more or less, in rifle cartridges similar to this one. Both produce about the same change in pressure and muzzle velocity.</div></div>

However, the U.S. economy is in a recession, and I'm highly in favor of other people spending money to no effect, which will help.
Besides, I think the Prometheus is a neat gadget as well as a status symbol. You don't buy a Rolex to know the time - they don't keep very good time - you buy a Rolex to demonstrate to the world that you have enough money to buy a Rolex. So, drive on, brothers!

Making perfect ammunition eliminates a lot of deduction when trying to determine a failed shot. The Prometheus has no wandering zeros or powder throw issues associated with other systems. It makes SD and ES lower than any other powder thrower.
If the ammo is perfect and the weapon/optic is sound; the booger hook can always be blamed, focused and corrected. So now, I keep working on my hook.........
