This is an appeal to anyone willing to help me validate my chronny. I've tried unsuccessfully to develop a 308 load, partly because I am unable to trust my chronny readings. They seem too slow (~200 fps). I am a member of the TCGC and test my loads Saturday mornings. I'd like to know if there is anyone out there willing to set up his/her chronny in tandem with mine for a handful of shots. Please, PM me.
