Look's like you could use some AR500 steel - so as to not cut yourself when measuring group sizes.
I got home from work today and decided I would start sorting everything by weight. What I found out is that my empty Reminton brass weighs on average 8 grains more then my Winchester brass. Taking that into account I've now narrowed my exstream spread down for my loaded rounds to about 5 grains. That's a little more along the lines of what I was thinking it should be. Now I'm wanting to go to the range this weekend to see if the Remington brass rounds preform any different then the Winchester rounds.

You know we have discussed this and where my position comes from. If Speedy did all of the research years ago and determined that weighing cases is a waste of time then it is not a conclusion that I take lightly as we have discussed this subject more than once. If you can set world records and be in the HOF there must be something to your process. When shooting I never give it a second thought because 99% of the people do not know how to set up bags correctly or judge condition when evaluating loads and a multitude of other things so if it makes them feel better then let them muddle along. Believe me if it make a difference then it will get done---now sorting bullets by bearing surface—YEAH BABY!!Like BOSS HOSS I do not wiegh brass
Here are a couple of 300 yard groups
There is a theory that calls for negative mass. In fact most relativistic mechanics do not forbid negative mass. It is very common in Area 51 to encounter wrecked alien space craft with negative mass propulsion systems. With as much work as Speedy did in area 51 it does not surprise me that he used negative mass alloys for cartridge cases.
Most of us operate in a world of positive mass where alloys have weight and that mass is associated with a volume of the alloy and once we confine that alloy to a certain external dimension the only place for variation to be is in the internal dimension.
Nonetheless, one must have a method of getting rid of weird components even if it is sprinkling them with dried mushroom powder and waving three buzzard feathers over them. These ten Berger 155.5 fullbore bullets have been sprinkled with dried mushroom powder and pretty soon I will wave the feathers over them to determine if any of them are weird.
I have been reloading now for a couple years but have never sorted my reloading components by weight. Up until this past week all that I used to weigh out my charges was a balance scale. It took too much time to weigh each component to make it worthwhile to me. I reload more for the cost savings then the accuracy although I do strive to get groups under 1 ½ @ 100 yards. This past week I picked up an inexpensive digital scale that seems to be Accurate to +/- .1 grains. I decide to go through and measure all my previously loaded rounds to see how consistent they are. I was very surprised to see extreme spreads of 15 grains. Meaning that when I weight the finished rounds I am +/- 7 grains from the average weight. For those of you that do sort your components by weight what kind of normal weight swings do you get? Do you thing that sorting your components by weight is worth it for hunting accuracy out to 500 yards?

I love this site probably more for it's entertainment value than it's technical value
