I have been wanting a 28 ga for a project for some time. I found one . A Crescent of all things. The serial # is 425* Crescent donated their records to the war effort but I heard someone here might know what year it was made. The barrels are not Damascus or twist steel. No proof marks. I am going to load for it,but I am having trouble find low pressure load data. Please don’t hate on the crescent. What can you tell me ? TIA
