I have some old .45 colt cases from my silhouette days still going .Think early 1980 something. I reserve them for lighter loads now and will lose the odd case to a split neck once in a while but they are 1980 vintage. Don't shoot the old [first .45]7 1/2 in Ruger much anymore either since the 4 5/8 and 5 1/2 came along.Son will get it and all the cases both old and new,One day! Guess I'll keep the old 4 5/8th .45 ,feels so damn comfortable in my hand. Thanks for the generous offers though.
