[QUOTE="djtjr, post: 521242, member: 13195"] Guys for thousand of you loading for the 300 rum or other hot overbore cartridges I have some questions. I built up a load settled on 93.5 gm of retumbo under a 200 accubond in rem brass and a 215m primer with the bullet seated to mag depth. A few weeks ago I built up in .5 gn increments from 90 to as high as 97 before starting to see pressure signs ejector marks flat trimers etc. I settled on the low node and took it out yesterday just to chrono it for a upcoming hunt to start building my click chart. In similar temp weather as the last excursion I blew the first 3 primer clear out of the case with some other signs of presure but not much. It was only the 2 nd or 3rd firing on that brass so would it be customary to get loose primer pockets after 1 firing any other thoughts? Is there a better brass option? How many firings are you getting out of your mag brass. Any other thoughts welcome. Thanks Don [/QUOTE]
