[QUOTE="rustyshackleford, post: 1904083, member: 59526"] According to Hodgdon you test to see if a load is overpressure or get a fair approximation if overpressure by measuring the case head expansion. You obviously can’t go by the book due to variations in powders, bullets, and casings from lot to lot. Then you have variations from throat length, chamber dimensions, and the dimensions of the bore itself. All these factors relegate reloading manuals to guides. For the record I don’t work up to ejector swipes and pierced primers. I’m pushing a 195 TMK from a 20 inch barrel at 2560. No pressure signs and win brass is still good on the 5th firing. This load is well over sierras max but gives me no pressure signs whatsoever. [/QUOTE]
