[QUOTE="hemiford, post: 2956760, member: 72104"] I have several rifle projects with quite long barrels that are inching toward completion. I know I'll have to experiment with different bullets and powders. I do not have a chrono yet but this new Garmin looks interesting. However, even with a chrono, the long barrels will give higher velocities without pressure signs so I can't compare velocity data with other shooters, as evidence of overpressure. So, starting off, can I only go by bolt lift and primer appearance for detecting overpressure ? [/QUOTE]
