Thread: 6.5 PRC loads

The velocity ES isn't single digit anymore, but over the last few rounds and some load tweaks I've got the 140s averaging 3055 fps with ES from 3046-3061 for 10 rounds across 6 grains of case weight variance. I'd say it's acceptable.

    Very good info. I found this to be the case with the Creedmoor as well.

    Tagging in as my gunsmith is building me one now to play with, using SAAMI reamer on a Kimber 8400 WSM action. Mag box will allow 3.00” OAL
