[QUOTE="Trickymissfit, post: 437021, member: 25383"] I'm sure there will be two dozen ideas here, but here's what I do: * run all the cases thru a full length sizer ** I will then check the cases for runout in the necks, and measure several to see if the neck walls are uniform * measure the overall length of each case in the lot, and then trim them all to the same exact length * deburr and ream the primer pockets if needed * weigh the cases, and sort them by weight * take the largest lot by weight and measure the O.D.'s (the I.D. should be to size) ** then do the samething with the others * if the O.D.'s fit in the window I plan on using; then all is well. I will then shave the necks on cases I plan on using in my smaller calibers (.22 and 6mm) * I then weigh them all again Everybody has an opinion on what's too much varience. In my bigger calibers I usually will work with +/- 2.5 grains per lot. Smaller stuff is about 1.5 grains per lot. In something like a 30-06 factory chamber I will often work with a +/- .001" on the O.D. as there's usually plenty of clearence in the neck. My small stuff will run in .0005" (O.D.) lots, with a set number as max for the O.D. and I.D. I know a couple guys that actually weight the amount of water a case will hold, but I don't have a need to be that precise. Another bunch I know swear that you have to load a round and fire it in each case before you ever start the above, but once again I don't own a rifle that good to even think about it anymore. Now back to the question what's good and not so good. If your using a threaded die to seat with, and always do a full length resize after firing; I'd not worry too much. But if you plan on using a bushing die I'd shave the necks to where they are all the same on the O.D., and toss out the bottom two cases in the group gary [/QUOTE]
