Jay, are you talking about the 300 RUM Federal brass that caused a stir a few months back? If so, I also would be quite interested in any report. How has it compared to the Remington brass?
I ordered a 250 piece lot. Looks like a good bunch. The only thing I have done sofar is measure the water capacity of a few cases. I must tell you that I necked them down to .284 to fire in my factory 7 Ultra. The capacities are as followed;
The Hi is 113.3 and the Lo is 112.2. The average is 112.935grs of H2O. It also looks like a 215 primer is used and sealed. Maybe someone else has measured wall variations.
