I have a single shot 6.5x58R on a Heeren action. Years ago from what I read it had a .262 barrel so I found someone making .262 jacketed bullets and got a few. Do to a lack of brass I only shot it a dozen times or so. A couple of attempts back then of making brass out of 9.3x72R did not work out well as I found out the neck (when I managed to get nicely formed ones) would have to be inside reamed. Got a reamer but lost interest in the project. Recently, I woke up and slugged the barrel and found out it is .264. I found some good brass and discovered it really liked Sierra 120 grain bullets. Now that good 9.3x72R brass is available I feel that I could do a good job of forming them. I may have to dig it all out and try again. If I had the single claw scope mounts it was made for I would have gotten around to it sooner.
