OK,
I F-I-N-A-L-L-Y got to a shooting range today, and was able to try out my customized 17HMR. The range conditions were pretty harsh. How's this for shooting weather: Late afternoon; mostly cloudy; half-value winds 10-15mph coming from downrange; 47 degree weather complicated by the intermittent wind, and partially numbed fingers.
Anyway, to get to my original intent of this post, the three (3-shot) groups I fired came to an average of 1.99" at 100 yds. I think that is
very good with a 17gr. bullet under those conditions. When I'm able to go to the range next, and hopefully have much better weather for shooting, I'll try to update this thread.
