[QUOTE="Darkker, post: 1279183, member: 81406"] 1) Excellent 2) This contradicts number 1. If you enjoy something, then doing that is never a "waste". 3) As Mike said, there is no "wrong" way to eat a Reese's. So here are some generalities to remember. Good book data is generated in Universal receivers and pressure barrels. These have tightly controlled minimum spec SAAMI dimensions, your rifle is going to be looser. No one lists lot numbers tested. Note that with differing books the charges vary, but very very rarely do the actual velocities? That is lot variation. Regardless of actual charge weight, when you match book velocity, you have gone over book pressure. If that doesn't bother you, then fine; but don't have any false imitations about what you are doing. Also don't ever use "signs" for pressure measurement, use velocity. Since the 1950's, NO ONE lists specs for brass cases, and CUP is NOT accurate when testing above roughly 45,000 psi. A random dude on the street can't stare or measure his cases and have any clue where he is for pressure. I've done enough with a Pressure Trace to feel very comfortable in stating that, generally, production cases begin to show "signs" around 70-75,000 psi, which corresponds with a few mfgrs Alloy specs for tensile strength. Do what you do, and enjoy it. [/QUOTE]
