17 HMR Acurracy Again!

I've been doing a little more shooting again, this time with a Remington 783 in 243 Winchester.  On my second time out to the range I figured I'd warm up with the 17 HRM before shooting groups with the 243.  I've been working on my technique and wanted to make sure I was in the groove before getting started with the 243.  I put ten rounds down the barrel, two groups of five at a hundred yards.  Here is the target.

 

I realize there is a shot pulled in each group.  What surprised me was the group on the left has four shots in about a half inch, and the group on the right has four shots in just under 3/8"!  You can bet I'll be testing the rifle out again on a nice calm day!
