The pic is mostly self explanatory. Rounds were shot over a Caldwell Chronograph ( sun screen type ) and velocities should not be taken as literal but comparing the figures is probably more useful.
Apart from the primers the load was simply something thrown together from components readily to hand, and a powder / bullet combination I have never used before. I picked a charge weight from a Hornady manual that was sub max but gave about 90% case fill. Each charge was individually weighed.
I know it's hardly an exhaustive test but for my purposes I consider it shows White River primers are looking up to the task and overall I would expect similar results to my standard Federal 210 primers. At this point I see no reason to not include some WRE primers in future load development.
