    Read the essay in my signature line and do a seating depth test. I run Nosler brass and 81g of H1000. Win brass is not nosler so start at least 5 grains below this its max!

    I use 74.5 gn h1000 in my win brass @ 3.535 o.a.l. With a case lenth if 2.610 using 190 smk's. Hope this helps.

    And ya this isn't max load but I'm getting .5" groups at 300 yrds so I stopped.

    Try them out if they don't work try something else, like the cci br2 that's what I use with that bullet and h1000.

    I am currently sitting at the range waiting for barrel to cool between strings and decided to test different brass today. After 3 shots of same powder and bullet between Winchester and Remington brass I have already found that the Winchester brass is sensitive to pressure. Same powder load and bullet all seeated to same depth and the Winchester brass is flattening the primers. No sticky bolt but primers are flat! What's the opinion on Hornady brass? Remington sendero in .300 win mag is the gun
