Just received my new 6.5 X 47 Lapua, hunting rifle and took it to the range to break in the barrel and do a little chronographing. Tried three powders: H-4350, Rl-15, Rl17. While testing, even though the initial groups looked good, velocity spreads and SD's were very high. like 80 fps and mid 20's. After a lot of head banging, I stumbled across the fact that my Lee Priming tool which I have been using for years was not completely bottoming out the primers. I took the tool apart and found that the white metal cam that pushes up the ram was badly worn. I switched to my Sinclair tool and Es went to 16 while the SD went to 5. Just thought, I would mention this in case anyone is using the Lee Tool might want to take a look at their cam and make sure it isn't worn to badly. If you have a new tool, a little lube on the cam might be a good idea. This is not intended to be a flame on the Lee Tool as I have loaded thousands of rounds over the years with it, just something to be aware of because priming is something I personally havae taken for granted.

Well, I also just received my new 6.5x55 30'improved hunting rifle from the same smith as your build.
What's say we get together before deer season and have a long-distance shoot-off?......you know the place....name the date and time........only this time DON'T let Ol' Roge forget the Butches!
Maybe there's not enough JD in Rogers diet?

Sounds good to me Lamar. It used to be that between the two of us we usually had everything covered. It's quite apparent that's no longer the case. Very scary!
