Is there any prevailing problem with Ruger #1's headspace. I traded for a 7mm rem in a #1 and got it with 3 boxs of 1x brass. The brass all had a bulge at the case head about halfway around the case. I found this odd, particularly from an action that is thought to be quite strong. So, I loaded a 5 140 Accubonds over 64 grains of IMR 4350 & a Fed 215 in new Nosler custom cases. Granted that is being a bit rammy, loading at 1 below max, but that is the recipe that I most often end up with after a workup and sometimes I rush things.
Fired off 2 of the 5 loads I put togather, no excessive barrel heat, but the same bulge and quite a flat primer. This leaves me a bit concerned about the headspace. However, instead of jumping to conclusions, I have put a coat of Hoppe's 9 BR copper remover in the bore and I'll look for some green patches in a day or two. It is either headspace, or a fouled or improperly broke in barrel. If cleaning it doesn't reduce the pressure at all, I will get a bit more abrasive defouler and really try to clean up the throat area in case it wasn't ever cleaned or broken in properly.
