Thank you. I'll order some Remington brass. I have made a couple of cases from 30-40 brass using a 308 die set a bit long to set the shoulder back. I trimmed to 2.115 and then sized in a 6.5x53R FL die. They came out perfect and chambered in my rifle. I have a 30-40 so I don't really want to use up my brass. The 303 is closer in dimensions anyway.
