Butch, what's posted is match 4, Light & Heavy. Light was shot at Hawks Ridge, heavy at Butner, along with match 5 LG. What we've been told is next time (at Butner) we'll complete match 5 (HG), and shoot all of match 6.
I figure we'll need some more people stepping up to volunteer to get things set up early. Due to the setup, initiation to the procedures in the pits, battery problem, etc., etc., we didn't start until well after 11:00 AM the first time. Maybe noon. for all I know.
BTW, anyone have an idea as to how large a circle you can see through a .22 bore at 100 yards?

Charles,
Not sure how accurate you need this but I used the similar triangle method to get a circle size.... 24" barrel would give you a 33.6" circle and a 30" barrel would give you a 26.88" circle at 100yds. Anyway, if it will help here it is... if not the circular file it is.
I had to run after the last match to get my guests home because it turned into an all day affair. But I'll plan on being there to packup next time. But it wasn't all for nothing, one of the guys is seriously talking about building a rifle even before we left the range. And he has asked many questions since then also.
Thanks for the update Butch!!

Steve -- you're probably ahead of me.
What I was thinking was that we lost an inordinate amount of time getting people on paper at the first match.
Suppose we had a piece of coroplast on the 900 yard line -- 100 yards away. We make a fair size black bull -- say enough to fill 2/3 of the bore for a .22 (which would be correspondingly smaller for larger calibers). 25 inched below that, we have a 1-inch orange spotting disk. Now, you just boresight, and the crosshairs S/B on the orange disk?
What do you think?
One alternative is to clone yourself 9 times, & we'll put one of each of you behind every shooter to watch the bullet trace. Technically, that's a bigger challenge.

Bore Sighting for 1K Alone
I had the same probem. We do not have pits and shoot clay pigeons on a sand bank in front of the targets. I wanted to get on paper at 1K. I ran my load on Quicktarget (one can use other programs). I came up with an elevation of ~ 36.4" at 100 yards. I made 2 points on the clean paper on the target back. They were in a verticle line ~ 36.4" apart. I sighted the bore at the upper mark and the scope at the lower mark. I shot one round and came very close to the upper mark. I then shot at 1K and was on the steel (~ 20" square) in about three rounds. Hope this helps.

On bad wind days at Sacramento which is most of the year we have the pit boss walk the line while each shooter puts one on the paper.This gives you 20sets of eyes in the pits looking for the impact and only 1 shooter firing at a time.
It is better than everybody asking to have there target pulled at the same time over the radio.

Jeffrey -- well, whatever works. 36 inches seems quite extreme.
I prefer the program at
http://www.jbmballistics.com/~jbm/cgi-bin/jbmtraj_simp-5.0.cgi
and to use a 1,000 yard zero, then read off how high you'll be at 100 yards.
Be sure to fill out the scope height portion -- the scope on my HG is 5 inches above the bore, and that does make a difference.
For a .308 caliber, using a bullet of 190 grains at 3,000 fps with a B.C. of .500, you're *about* 27 inches high at 100 yards. For a 6mm, a 105 at 3,100 with a B.C. of .520, *about* 25.0.
The high-velocity magnums with a high B.C bullet can run as little as 22 inches high at 100 yards.
* * *
Essentially, we did as Lynn recommended. We had 32 HGs and 33 LGs, with most people using different rifles in HG and LG. At 1 minute per gun to get on paper, that's a little over 1 hour total time; time we don't have, esp. since that's a lighter turnout for us. in IBS, we're required to have a 6-minute sight-in period in addition to any informal "getting-on-paper" time.
* * *
OK, at Hawks Ridge, we did not have pits, but used clay birds on a couple of banks. At Butner, we have pits, but no birds on the banks. Assume that for any band-new system, we're going to lose a lot of time the first time out. But it is still a problem we have to address.
The worst problem was low shots -- the people in the pits can't see a low round. And of course, the first shot out of a cold, wet bore usually goes low. So if you're a little low generally, and the first shot goes lower still, no one sees it.
Wide is less of a problem -- I think if we use two different colored spotting disks, with one for a hit and one for a miss, we can take care of windage. With a 6-foot wide target backer, holding for the edge of the paper (backer) after a miss gets you another three feet with each shot.
Highpower shooters who have a no-wind zero may have the right idea. Start there, and take a guess on windage. Likely you're on paper with the first shot?
At Butner, the bigger problem seems to be elevation. You can't see a low round, and you can't reach up high enough to mark the backer with a high miss. The different colored spotters would at least address the high misses.
* * *
Just a guess, as it is early days, but I think the regulars will get a 1K zero and adapt pretty quickly. The bore sight target should address the new shooters.

for the present 308 Win. (Next week the 6 BR gets here). My velocity is only 2754 and the bullet is 175 SMK. So all in all not a very good rifle for the distance. I agree that better bullets going faster will have less elevation at 100 yds.

sorry to change the subject
man steve that is a mighty fine heavy gun group ,are you going to iowa?if you are ,i better double check my tune.and charles sir it looks like you shot very well too,man the bibs are mainstream now for long range,thats funny.and i noticed mr thomas ellington shot well with his dasher,i never thought i would see him shooting a 6mm.well congrats to all, great shooting.i hope the range works out for you guys. tim in tx

Butner will work out fine. jsut typical issue when you change venues and have a different system.
Yea my gun is shooting pretty good right now. Charles HG looks good, but right now Bob Rosen is the one I think has the hottest HG gun. Hopefully Bob makes it out to Iowa. and yes Dave, Scott, and I will be rolling in for Iowa and then heading further west for the 600yd Nationals the next weekend!
can't wait for that big ol' steak from that Steak joint over near the Knoxville speedway. Wish I was at the Speedway right now... those sprint car boys are getting it on this weekend for the big prize for the Knoxville Natl's.
time to head home.... 89hr week and haven't eaten today.....
