[QUOTE="BountyHunter, post: 283607, member: 12"] JE Tom Sarver in Ohio shot a world record 1000 yard 5 shot 1.4" group, 50 score and 5x with 338 Lapua brass that had been shot 54 times. it was finally thrown away at 80 reloadings. he annealed after every firing and FL resized. see the article on [URL="http://www.6mmbr.com"]www.6mmbr.com[/URL] documenting that . As for case head separation issue, IMO that is a red herring. That always comes two things: Excess headspace and from improper set up dies and FL sizing too much and pushing the shoulder way back and causing the case to be pushed back and then stretched forward repeatedly when fired, creating that line where it separates. the excess headspace normally can be compensated for with die adjustment as described above unless it is just way to much, and that requires a barrel setback and rechamber. Never heard of it happening any other way nor anyone ever documenting such an instance! Brass just does not decide to separate on a line without that happening. in 1 K BR, we routinely have guys use mag brass for 30 plus reloadings and pushing the PSI limits. I know guys using one set of brass 4 years and two barrels. When the brass is thrown away, it is normally from loose primer pockets or hardened necks and not annealing. I have some Norma WSM brass (which is softer) that has over 25 reloadings and annealed each time, and still good. Pockets are starting to get loose and I just rebarrelled, so I just set up another 100 for that gun. If thechamber is properly headspaced and the dies are set up right, case head separation do not happen. If chamber is wrong and/or the dies are set up wrong, it can happen in 3-4 reloadings at med PSI. Bottom line in either case it is not a brass problem. One case it is a true chamber headspace problem and the other is "operator" headspacing.:) yes there is a major difference in quality between RWS and Lapua compared to the rest. Those two are annealed from the factory and much harder brass. Primer pockets last way longer compared compared to the Rem-chester brass that will go in one firing of a load that lasts forever in Lapua. I will gladly pay $2 for that brass for the cheaper that is only good for 4-6 reloadings. It is an amazing dicotomy that on this site we have guys with $3-5K guns, $1.50-$2 custom bullets and 40 cent brass. all I can say is, DUH Old top dog LR hunter and 1k shooter told me years ago, it takes three quality things to have a top notch LR load and gun, "bullets, brass and barrel". Miss anyone of the three and you are SOL. Lapua mags can be extended also don't forget and the Lapua AI will be 150 fps plus over anything else other than the 338-408s. Anyway, just my opinion and that is what makes life fun:D BH [/QUOTE]
