[QUOTE="Bart B, post: 1795841, member: 5302"] The metal properties in barrels don't significantly enough to change its resonant vibration low frequency and the several harmonic higher frequencies across most temperatures they're shot in. The zeros will change a lot more with altitude and powder temperature changes. Get zeros for each. A good barrel won't change point of impact across 30 to 40 shots fired every 15 seconds and it gets very hot by the last shot [/QUOTE]
