Got my shipment of the 338 edge Bertran brass from Shawn Carlock Defensive edge.
Took 20 brass and checked them out by weight and found ES- 1.5 which is out standing. Then checked head space, siezed down and trimmed brass .
Loaded 90 gr H1000-Fed 215match primers pushing 300 gr bergers at 2815FPS. Checked concentricity .0015 with Bertran and best ever with Remington was .0025
Three shot group at 300 yards 3/4 inch, very happy with that.
Then took my Remington loaded rounds with the same load and found the three shot group open up to just over 1 1/2 inch at 300 yards.
This brass is equal or better that Lapua brass that I have used for the 6MMBR and 22-250.
Bottom line is ,yes it cost more than Remington but is much better and I expect to get over 15 or more reloads before primer pocket goes away which reduces your cost of brass.
Thank you Shawn for you bird dogging to get this brass for us 338 edge shooters.
