You need to start low and work up. You need to know and understand pressure signs and when to stop and back off. This includes measuring brass at approximately the .200" line for expansion growth and not working up a max load in 20 degree ambient temperature that you will be shooting when it is 85 degrees out (ask me how I know!). If you don't know and understand this process, I recommend that you find a mentor to teach you. Reloading is serious business.how do i do that by not being in the danger zone ?
I will add that RL 26 may get you more fps at a safe pressure. I am using it for my son-in-laws 7 Rem Mag with 168's.
