FWIW...again...
Got my new 50 count of Peterson '06 cases, which were nicely boxed with a hinged, MTM type plastic container. They're annealed nicely, and after I ran them through the f.l. resizer, they ALL measured @ 2.385" (plus-minus less than .001" on some). Every case had very near the same "feel" of "squeeze" as they were run through the sizer, very lightly lubed; I was quite impressed at the uniformity. AFAIC, no trimming needed whatsoever on these, and I won't run them with the pocket nor flash hole uniformers, either. They do get chamfered and deburred, though, as they should, and they're ready to reload and get fire-formed.
Working the new "Pete's" were very similar to the new, unfired, f.l. sized Lapua '06 cases I have on hand. The Lapua cases I have, and after f.l. sizing, all measured @ near 2.385," too, with a plus minus of .003" on some. Otherwise, they were all very uniform and compared well to the new Peterson's. I don't pocket nor flash hole uniform on the Lapua's, either, but do properly deburr and champher, and they're ready to reload and get fire-formed.
Now, on the other hand as a comparison... and FWIW,
Just a week ago, I got a 50 count bag of new WW cases in .270 WSM. I went through all of those starting with f.l. resizing, too. ALL of them had a different "feel" to the "squeeze" running through the sizer, and I had to make sure I had enough lube on them as I did the job (needed quite a bit more lube on these than I did on the Pete's and Lapuas). When it came to case length measurement, the whole lot varied from min. trim length of 2.090," to 2.11" (.001" over max.). So, I trimmed the whole lot @ 2.090" (luckily, the shortest cases were right at trim length). These cases all got their primer pockets and flash holes uniformed after trimming, then champhered and deburred. They all did load up nicely though, nonetheless, and are awaiting their fire-forming.
Just a little comparison here as to brass brands, new brass prep according to my method, and nothing more. My new Remington, Winchester, Federal and Starline cases, pretty much always get the full treatment of prep when I open a new bag. Just gotta do it.
