I actually used CCI 200 std large rifle with my .375 loads which utilized over 80 grs of IMR 4831 powder with no issues. Mag primers can sometimes elevate pressures and I only use them when specifically called for with some of the hard to light powders like some ball powders or really large doses of slow burning powders. While it would seem that my .375 loads would scream for mag primers I never used them.
Went to the range today for some testing and found that my best 3 shot groups came from the CCI BR -2's that I use for my cz 550 in .308! Thirty rounds later,my shoulder is a bit tender but at least I have no more plaque on my teeth..!
Mule deer and Colorado elk seasons almost done! Hunters driving farm roads, looking for racks, their PH driving them along, I ask that you not pull into my drive. The buck behind me, on the boundary line of the GMU somehow knows. The hunter laughs, I would invite you in to see my Searcy rifles but social distancing prevails, darkness arrives and the buck slides away into secret tree grove...
i‘ve taken to heart a suggestion to tell my story about a lion hunt 37 years ago. ‘I don’t know, but am thinking there are site rules as to posting and file type. Three of the four posts (chapters?) are done, I took time away from here to write up the story. I have a couple of photos too.
also, I’m going to dissemble the rifles and see if Butch may have signed them. I’ll let you know.
