[QUOTE="Hummer70, post: 1606719, member: 85770"] I realize this is a rather outdated thread but thought I would pass on experience I had with Lapua 30.06 brass. I won the Palma Trophy Match at Camp Perry in 85 and 86 using new Lapua brass and every one I shot did well but several of them had the primers fall out when I opened the bolt. My load was 54 gr. 4350 which is not max in any manual. The case heads were obviously soft so I never used Lapua 06 cases again. Guys I know that load Lapua 308 do not have the problem. That is the last Lapua 06 I bought. I just fell into a Rem 7600 270 and while I have never been a 270 enthusiast the price was right. I have some commercial 270 cases I will use but I know from experience that most commercial cases will have the primer pockets get loose in 5 to 7 rounds. I will probably at some point convert some LC 06 Match cases and that will hold me for years. I have one 30.06 match case I have loaded 157 times and primer pocket is still snug. Measure the dimension of the case .200 up from rim. New 270 ammo will measure about .465" at that point. Next measure same place after firing. You will most likely find they have expanded to . 471/.472 range (SAAMI CHAMBER). I was lucky with this rifle as fired case came out at .468 which means I don't have to worry so much about incipient case separation. As a general rule you will find US milspec brass exhibits a much longer reloading life. Keep in mind not all FL dies are made the same. CIP I have several 30.06 dies I have picked up over the years and I have them marked as to the size they take fired case down to. I have 06 dies that size .466, .468, .470. I polished one set out to .470 and use those on the jumbo SAAMI chamber rifles I have to give long case life. I have not measured my 270 dies as yet but I expect to size a base size dimension in the .468 range. To give a idea of how long cases can be used I have 500 LC 06 match cases dedicated to my No 1 course rifle and that same brass has been used since 1982 and it is on it's third barrel as every barrel since has been chambered with the same reamer that cuts a .469 base and I use the .468 die on those cases. Simply put the less the brass moves the longer your case life so if you plan accordingly and use the proper dies your brass will last and last and if you have US milspec brass you are set for years. I forgot to add that I stress relieve the neck and shoulders before sizing them down to 270. I would fire them once and stress relieve them again and from then on about every third loading as cases will last and last and last. [/QUOTE]
