NO 4MK1 Range Report

I had a B-Square scope mount for a NO4MK1 rifle and aquirred one a while back. I put an old Weatherby scope on it. Shot it today at 100 yards. Wind blew over the box with 10 pounds of rocks holding it up twice and I nearly froze to death. Is'nt Montana grand. Shot a ten shot group before I left. Came out at 2 1/2 inch except for the pulled one. Ammo is some South Africian ball I've had. Wish I could find some for sale. The rifle is marked on left butt socket No4MK1 No Maker Marks. Marked on left butt socket AO 1943 https://www.milsurps.com/images/imported/deleted.gif
