This past weekend I was shooting in the monthly 600 yd. IBS benchrest match at the Piedmont gun club in NC. They had 39 shooters including may current record holders. We shoot a four target(five shots per target) aggregate in both light and heavy gun class. I shoot my light 16 1/2 lb. rifle in both classes. (this was heavy class) I had been aggin' in the mid to low 2" range. This match my group agg. was 1.808" and my score was 193. I came in second (2) in group and second in score (2) which gave me #4. Another shooter came in first in group and third in score so he ended up with a #4. The other 37 shooters had higher numbers so that puts us tied for first place in the grand agg. Since his group agg. was lower than mine, he won the match. Anyway, it was the first time I went below 2" The cartridge is the 6mmbrx in a rifle I complete4y built from scratch. Richard
I had a buddy make a gun from scratch once. Did you use a boring bar and cut raceways for opposing lugs or did you do it with Weatherby style locking lugs? He made his with Weatherby style lugs because it was what his machinery could produce.

That's good shooting. What was the shooting position/condition? What gr bullet are you slinging and how fast? What twist on the barrel?
I shot some 3 1/2" groups at 500 yds with my .243 prone using 55gr NBT's at 4,000 fps. At 650 yds my best groups were about 5.5" and I was thrilled because I am not an experienced BR shooter...just an experienced shooter.
One thing I noticed was that even though my groups were "tight" they were fairly left or right depending on wind. Sometimes more than a foot! I always thought that judging the wind was, by far, the greatest challenge or skill for a guy making a shot that had to hit a "spot".

Good shootin' Rich. For those of you that aren't familiar with the 600 yard BR game you should know that Piedmont, where Rich shot those targets is home to serveral world championship winners and to win a relay or a match there is a big accomplishment. Whole bunch of good shooters have had their a** handed to them at Piedmont!
Thanks guys. 7mm freak...............I guess I hedged a bit. I bought a Stiller Viper action and a Brux barrel(8.5 twist) A friend cut the stock on his duplicator but no inletting or barrel channel...Just raw! I did all the stock work and the metal work..........thread, fit/headspace and chamber the barrel. The trigger is by Jewel and the scope is a 40X Leupold competition with fine crosshairs. The bullet is the 108 Berger BT traveling right at 2950 fps. 33 gr. of Varget along with a CCI 450 primer. The weather conditions were very good. (at least in the morning) It changed for light gun in the afternoon and averaged in the 3" range:(. We shoot two targets at one sitting with a 2 min. break between targets. So it was 1 1/2 hrs. later until I got back on the bench for the last two targets. You can see how the first two are similar in bullet location. (I made NO scope change) Targets 3&4 the group shifted to the left which caused me to loose valuable score points. Had I been able to get 1st.in score I could have won the grand agg! Disclaimer: That load was safe in my 6mmBRX chamber. Richard
Greenhorn..........Thanks! Its called wind! Some of it is hard to read. Mind you, these bullets have a higher BC then those Parker MH and Rocky Mt. bullets Luke has. That shift was not even perceptible to me and I had a wind flag in my scopes view. So when shooting those .45's with no wind flags and very often off less than concrete benches, small groups will be pretty hard to come by on any regular basis! Richard
I was there DBbut didn't do as good as Richard. My avg was 3.1. Richard,Bill and I are at most of the 600 yd shoots at piedmont.We love to shoot. I am getting ready to meet them at our club range in just a few minutes.Got 3 savage muzzleloaders and try a new load in my bench rifle. If you put me on a 1-10 scale,Richard would be a top #1 and I would be a bottom #10. I have averaged a few shoots in the 2's but mostly I am in the 3's. Richard you know I have both fingers crossed for you and Bill for one of those less than an inch groups.
