IMR4831 is one of my favorite powders. It performs excellent in my son's 7mm Remington Mag, 2 of my cousins 7mm Remington Mags, and my 243 Winchester. As stated above it is a pain to meter and might cause you to do what I did, buy a RCBS Chargemaster. Now I actually look forward to reloading with it

It really likes a full cartridge so fill up a case to the bottom of the shoulder and start from that charge.

Snolden, I'm thinking that statement should've come with a disclaimer
