I just received 2 boxes of Peterson Brass. I have 6.5 Creedmoor brass. I have measured all 50 cases to see how they are. Case length 1.910- 1.912.5 .I called the number on t h e card included and believe it or not got an immediate answer. Their cases hold 50.4 grains is water. My Hornady cases hold 52.2 according to Hornady. A difference if 1.8 grains less capacity. I put in my redding compitition S full length die and it had no resistance. I neck sized with my .290 nitride bushing and agan very little pressure needed. The head space was 1.530-1.531.The case weight was 167.6-169.2 with an avg of 168.52. Extractor groove 0.0400. Case head stamp 0.467. I neck turned and the necks needed very little turning as in less thsn.001. I used a RCBS hand case neck turner. I can only compare these to my Hornady cases as that is all I have shot in my 6.5 creedmoor. The cases come in a cLear plastic box with about 1 inch foam pad on top plus 3 cards.1 with their phone number asking for my feedback. 2. Diclosure on load and how internal dimensions are different for vario u 's case mfgs.3. Data card for recording loaded cartridge info including a Times loaded section at the bottom. I'm totally sold on these and I bought through Brownell's for $39.99/ box. If you do some research you'll find they have bought all new modern equipment I have no comparison to Lapua but these are made in PA. USA. Oops forgot to say they are annealed!! Used a primer flash hole debuting tool and not one needed any thing.
