[QUOTE="Tumbleweed, post: 588249, member: 9281"] Not sure what bullets you're using, barrel length or if this is close to your max load. Something I have noted in the past: I rifle's barrel can only burn so much powder. I have worked up a couple of loads in my 300RUM where you get close to max load or even a tad above and you stop gaining velocity even with more powder. The pressure signs seem to increase on the case but you can get to a point that the rifle will not produce more velocity even with a grain or two more powder. In this case I have backed down the powder charge until the velocity just starts to fall off. So to answer your question, in your big case chances are you won't notice a difference with .5 grains unless you've got very tight ES with our current load. Hope this helps. Of course, watch for too much pressure! [/QUOTE]
