[QUOTE="Deleted member 46119, post: 1227157"] Absolutely. You are sub 90% fill with a sensitive powder in a magnum case. If using a magnum primer as well you may be (probably) creating a secondary pressure wave. There are a limited number of powders that behave well at fill rates below %90. RL-22 is not known to be one of them. 2 things I see from your description and pictures. JMO but and educated one. 1) your split case picture looks great. From that picture, case head separation is not the problem. 2) the picture provided is very nice quality. Unless there is some form of graphic aberration, I see a bulge at the base of your brass caused by the over pressure secondary wave. If it were me (IIWM) and not saying you should (anti lawyer Californian) Use at least the minimum reloading manual charge of 67grains of RL-22 for a 300WM loaded with a 180 TSX. If the problem persists, change powder, primer or both. This is of course standard reloading manual practice. Do not try to resize the bulge out of the case, it will cause case head separation (physics is physics). Instead, if you want to salvage the brass that is bulged, get: Belted Magnum Collet Resizing Die from [url=http://www.larrywillis.com/]Innovative Technologies - Reloading Equipment[/url] It's a great tool to have especially of you shoot multiple rifles with belted magnums of the same chambering. Example, I have multiple 300Wby. Each rifle has it's one lot of brass but if I need to move brass from one rifle to the other, I use the collet die as part of the brass preparation. [/QUOTE]
