[QUOTE="MudRunner2005, post: 972107, member: 12995"] I've found with a Weatherby and lots of freebore, to load about 0.005"-0.010" short of magazine length, then ladder test your powders from there to find where it likes it. Also, if you like the way your .300 Wby is shooting, you should consider having the chamber opened up to .300 Ackley Magnum. It's basically an improved version of a .300 Wby (sometimes called the .300 Weatherby Ackley Improved 40*) that has a 40* shoulder instead of the rounded Weatherby shoulder, to improve accuracy and case life. You can form brass out of your .300 Wby brass you already have. All you have to do is load it up and shoot it, and out-pops a fully formed .300 Ackley brass. You will need custom dies made, but in the meantime (after fire-forming) you can use an RCBS .300 Wby neck-sizer die and size just the neck of the .300 Ackley brass, since they have the same neck dimensions. Just a little tip I've learned along the way with mine. And also, for load data, you start out using .300 Wby load data and work your way up to find your rifle's preferred charge. It's just something to look into and think about. I have a buddy who has a .300 Wby, and after showing him my .300 Ackley, he's considering having his chamber opened up to it, as well. Oh, and like Calhunter, I also use IMR 7828 SSC in my .300 Ackley. [/QUOTE]
