Thread: Hornady 150sst load-30cal

So load accurate but now my concern is variation in speed as last night fired 3 shots and the chrony read in order 2624fps, 2482 fps & 2534 fps. At an average of about 2550fps i am happy with speed as i was guessing about that from mates who run the same combo or have in the past. Is this an issue that there is such a difference?
Also ran my 125s through and they were a hair under 3000fps with 49grs of 2206h and fed magnum primers but mate said not to run magnum primers in non magnum calibres but there was no pressure signs and only a 7fps variance in the load.
