If you take the extreme spread and divide by the median case weight your extreme spread as a % of weight is about 2.3% not bench rest but probably not anything a hunting rifle would be able to tell the difference. I dont think im going to start sorting brass for hunting especially when they are shooting tight at the ranges I test and hunt at.
Also when I was prepping my Bertram I had some laying on my bench and in the bright sunlight i could see the top half were definatly a darker color showing an anneal line.
I have fired about 50 rounds of the Bertram 28 Nos. and so far it is working just fine. One nice thing is one of my 28's I have been shooting 162 gr because I couldnt get over 2950 fps with 180 gr bullets without heavy bolt lift and ejector marks using Nosler brass. today with the Bertram I worked up to 3082 fps with Berger 180's no sign of pressure and right at 1 moa and ES of 13
On exact same loads with both brands of brass 162's accuracy was very close- both sub .5 moa.
Nice to hear the Bertram Brass is going well. I'm currently in the middle of a custom build in 28 Nosler and have stocked up on some Berger 195 eol pills and picked up some brass off Bruce Bertram as well.
