As the title states I am curious about the options for quality brass for a 7-300 Win. I would very much appreciate any info from any of you out there who have ran this cartridge.
I bought some Winchester brass at the suggestion of my gunsmith and some reading on the Ballistic Studies website on the Practical version. When I opened them it was pretty standard for what I have experienced with WW brass in the past..Out of the 100 pieces I had to throw 13 of them in the trash just from a visual inspection. The necks are not cut straight and just seems like the quality is not the greatest. Only fired a few of them 1 time so far.
I bought 200 pieces of Norma brass and it was as expected also. Very clean, straight and good quality. The problem that I have now encountered is that after the 1st firing from my rifle, I can push the primer into the pocket with my finger and it falls right back out. I have ran into loose primer pockets when running very hot loads, but never to the point that it won't hold at all. Most of the times I have seen this problem is when I have reloaded the case several times at max charge. Even then, I have had to at least tap the case on the reloading bench to get the primer to move. But after a single firing, it won't even begin to hold the primer. I have been shooting 180 and 195 Berger bullets and Retumbo powder. Charges with the 180 have ranged from 69 to 75 grains, all with the same results on the primer pocket. Charges with the 195 have ranged from 69 to 71 grains with the same results.
So my question is this..Have any of you got a suggestion on what brass to use to try to get more than 1 shot from a piece of brass??
Do i stick with the Winchester? Or are there better options for this cartridge?
