Thanks for your quick answers.
Jim, I realized you were from Victoria just after I hit post. I grew up there. So, you are right that we don't have to go south to get answers, but I find there is a lot of experience particularly on the M1icon's and some of the other US made WW1 & WW2 rifles I own. Its the numbers of 320+ million to 36 million people. Also, thank you for the lapping video. Very informative.
On the Canadianicon sites, it always seems to turn into a ****ing match with who has the best answer. A lot of chest puffing. It gets frustrating, so I went searching for a site that I could ask a question and expect good answers without being schooled.
