For you 6.5x55 Swede shooters, what velocities do you get as compared to the published values?
I loaded some 140 grain Sierra Match Kings with a 43.7 grain load of RE22, as per the Sierra manual. The manual says that should give me about 2600 FPS.
My ProChrono gave me me a very consistent 2290 FPS - way low. I am always suspicious of my chronograph, but have no way of knowing if it is giving me bad numbers. I am shooting a very accurate M96 Swedish Mauser with a 27 inch barrel, so I'm not losing velocity from a short barrel.
What kind of number do you get?
