Seems like everyone pretty much agrees for a change....as for me, I do separate batches of brass by make and times reloaded. ( as someone else said , don't know why..I just do. ) I DO inspect my brass and mic it , I have found several calibers really stretch ( 460 , 357 max , and even the 357 mags ), I like to keep a consistent crimp. Once I get the powder thrower adjusted with my load , I may throw 20-25 loads to a loading block...with a light , glance at each and every case for a visual inspection of powder. ( esp if using bullseye or maybe unique , very easy to double charge ) After checking the weight of the batch ,then I finish loading the 20-25 in the block and start the process over again , I will weigh the last charge of every batch. Just the other night , I found I had forgotten to tighten the lock nut on the adjusting thingamajig on my RCBS powder thrower...I dumped that 20-25 batch and started over again. I have never weighed the brass or bullets...35 to 50 yards mostly , I can put everything into a 4-6 inch circle ( open sight from a open stance )....that's fine for hunting where I hunt at. As far a working up loads , I've always used CCI primers....I will start with close to minimun load and work up with a moderate load , and usually do a few with max loads, assuming everything looks good on the lesser loads....or pick a velocity and try to load to it , watching for pressure signs as you go. I usually test for the accuracy of my loads with sandbags...after that, its all offhand or with a mono stick. Just be careful with the fast burning powders , its awfully easy too screw up.......also , turn the cellphones off...no TV ....keep your mind on what your doing ! OMHO Good shooting!
