The sun finally came out here so I could properly chrony my 4.7 gr Unique/158gr LSWCHP loads today. Big surprise. Last time I tried it was overcast and the only reading that looked real was 795....the rest read in the 400 fps range which I knew was incorrect....assumed 795 was a real read. Today 5 shots from my LCR averaged 910 fps! 908,917,919,914,893...all about 100fps higher than I expected from what I've read and heard here. Double-checked my old RCBS scale with an even older Pacific (c. 1964...the kind that came with a little tube of weights). It indicated that, if anything, the RCBS charges were a tiny bit light...4.6 or so. That leaves the chrony--a new "Shootingchrony" made in Canada ordered from Midway. Any thoughts? If I'm really getting that kind of velocity with that load from a 2" barrel I'm very happy but seems too good to be true.
