I have never used a factory load either that was as good as my carefully developed loads tailored for each gun I have, but stubblejumper is correct. If you are willing to test various brands in a particular rifle, you will find one that gives you better performance than the others. However, no-one can tell you which brand it will be for your individual gun!! Sorry!! You have to discover this by testing each brand. And, it can also vary from ONE LOT NUMBER TO THE NEXT in the same brand as well!! So, when you find the load that is better, buy several boxes of that lot number, so you don't have to go through the testing drill too often!!

Keep yore powder dry!!
