Can anyone tell me what Hornady has for Minimum and Maximum brass length for 6.5 PRC, what they recommended trim length? I cannot find what I am looking for and my Hornady Reloading manual doesn't have the PRC.
Have you fired it yet? Your chamber length can have something to do with how you trim - if you have a short chamber - you may see signs of deformity around the rim of the mouth...if so, measure back to a thou below the low point and use that as your trim length.
If not and you are just looking to make them uniform, measure maybe 20 pieces of brass, find the shortest one and trim all of them to that length.
I have already fired them and some had been reloaded for several sessions. Just wanted to get them all to the same starting point, some measures long and others were only a few thousand different than minimum. This is all Factory Hornady rounds I had used to help break in barrel.
