Being an engineer little things intrigue me. I was at the range today, and I brought one of my M1 Garands, and my 1903A3. After shooting the exact same ammunition out of each (150 gr A-max in front of 47 gr of IMR 4895 out of Federal brass) I noticed that when the spent brass came out of the 1903A3, the brass was cool enough that you could hold it in your hand, where as the brass from the garand was too hot to hold for about a minute. My question, is what do you think the cause of this is? Any thoughts?
The only thing I can think, is that mabye the chamber of the Garand is tighter than the 1903, causing it to have a greater pressure hence greater temperature.
