Without really looking I reloaded 100 rounds on the week-end , at the range i had 6 casings where the primers fell out in the magazine . failing to allow the weapon to go into battery and messing powder everywhere.
I was lucky that nothing blew up …
I picked up the casings at the range and hadn’t properly checked them – but it looks like “durapoint” (or somthing like that) reload’s, in the orange box, has been reloading berdan primed casings with boxer primers .obviously drilling out the old primers anvils which works just fine with the primers they use, once … but when reloading the primer pockets are stretched.
My winchester primers seem a little small and they were falling out … while they felt fine and looked fine on the press.
Needless to say I ditched all the berdan primer casings from my brass stash and now will sort my range brass a little more closely.
