[QUOTE="el matador, post: 1470804, member: 12193"] I would fill the case all the way to the top with some RL33 and weigh it. Multiply by 90% and that will be pretty close to your max charge. I've done some testing with this powder in my 338-378 and I didn't see significant pressure signs until I was compressing the heck out of it. Lapua brass can be pushed harder than the Weatherby stuff, too. For more consistent reloads using compressed charges you may consider using a drop tube. My cases hold 132 grains of powder when filled to the brim and my max loads were 118 grains. I got really good velocity and decent accuracy with the RL33 in my gun. I only found the accuracy by pushing it hard though, and if you understand the Weatherby brass situation you'll see why I'm not liking the RL33. Brass are north of $3 each and they don't take abuse too well. With your barrel length it should be easy to hit 3000 fps with those bullets. Hopefully you can find the accuracy you're looking for with a nice comfortable case fill. [/QUOTE]
