joecichlid Posted May 28, 2009 Share Posted May 28, 2009 HSMITH, at 10 yards is the bullet impact at the top, center or bottom of the 6 MOA dot? I am thinking about trying a closer Zero and trying to get used to it over the next few months. Joe W. Link to comment Share on other sites More sharing options...
HSMITH Posted May 28, 2009 Share Posted May 28, 2009 Joe, details will follow in about a week, maybe 10 days. Link to comment Share on other sites More sharing options...
jasmap Posted May 28, 2009 Share Posted May 28, 2009 I set mine at 17 yards so I can be nearly dead on at longer ranges and for head shots at close range I can just aim at the top of the A Zone. Link to comment Share on other sites More sharing options...
jid2 Posted September 1, 2010 Share Posted September 1, 2010 Bump for this thread to say thanks to Jeff for making the spreadsheets. I've known about all of the factors, but never compiled them mentally to understand how they interact. I had my zero set at 10 yards and it was too much work making the compensation for longer shots. So I re-zeroed at 20 yards, and now the shoots are easy to make out to 50 yards and I just aim 2" high for the up close ones. And now I can tweek these spreadsheets and go out with calculated data points to verify with empirical data (shooting)! Link to comment Share on other sites More sharing options...
RH45 Posted September 1, 2010 Share Posted September 1, 2010 Even though I still have an upright mount on one of my open guns, I tried an old, Barry mount on the other open gun, and even though it is a PITA to sight in, with it set dead on at 50 yards, pretty much everything closer is somewhere in the dot. I just may have to change the mount on the other one. Link to comment Share on other sites More sharing options...
gunsteel Posted September 1, 2010 Share Posted September 1, 2010 I have been shooting a S/V open pistol for 16 years. I have owned every dot that has been available looking for that extra edge. C-More is basically the best for me as I never had any trouble finding the dot and it always stayed true when sighted in. I have always sighted in at 15 yds. (1/2") groups then went back to about 40 yds and tried it. My pistol would rise about 3 or 4 inches at that distance. Main thing at that distance is the horizonal setting. It may shoot perfect at 10 to 15 yds (you think) but if you have to shoot the 50 yd. standards it may shoot 6" off to the right or left. Fine tune there and your in business.

joecichlid Posted September 16, 2010 Share Posted September 16, 2010 Chris, I'm with the "short distance" zero theory. On thing, in addition to the other posts - after you zero at 10yds or so, try shooting off the "top of the dot" at 50. Often, it works out pretty cool. Because of the minds tencency to "center things," it feels easier to align something specific, like the top of the dot in the center of the target, as opposed to forcibly "holding low." be Brian, I need to give this a shot, pun intended. With the Nationals right around the corner and no telling what the stages might have I best practice up on everything. Joe W. Link to comment Share on other sites More sharing options...
Aircooled6racer Posted September 16, 2010 Share Posted September 16, 2010 Hello: I shot my open pistol today. It is right on at 10 yards. 1" high at 25 yards and 3" high at 50 yards. That is with a Quinn II mount and a 12MOA dot standing up It was even grouping 3" at 50 yards(Thanks G-Man). Thanks, Eric Link to comment Share on other sites More sharing options...

It might have something to do with that big ass dot.... You shouldn't see more than an inch or two at those ranges.

Aircooled6racer Posted September 16, 2010 Share Posted September 16, 2010 JT: I was standing up with a breeze blowing behind me. I was very impressed since the last time I did this with another mount and could hardly hit the paper at 50 yards It should be ready for nationals now.

n1guess Posted September 11, 2011 Share Posted September 11, 2011 what if you have the new 45 degree scope mount off the side of your gun that puts the dot closer to the bore....you wont have the big swings that you have with it on top....so do you still do the same distance??

BoldasLions Posted September 16, 2011 Share Posted September 16, 2011 50 yards. Have the bottom of bullet touch the top of the dot. Shoot from rest and bring magnification. BTW: C-mores are very sensitive to adjustments. Link to comment Share on other sites More sharing options...
Pete Whyte Posted September 17, 2011 Share Posted September 17, 2011 What do you mean shooting off the top of the dot? I've never used one before. Would you use the dot as a clock and use 12 o'clock??????? thanks. Link to comment Share on other sites More sharing options...
Singlestack Posted September 17, 2011 Share Posted September 17, 2011 What do you mean shooting off the top of the dot? I've never used one before. Would you use the dot as a clock and use 12 o'clock??????? thanks. At 50 yards, an 8 moa C-more is covering 4 inches of target. That's a pretty big aiming point. Use the very top of it (12 o'clock) as an aiming point instead of the whole thing. Link to comment Share on other sites More sharing options...

zhunter Posted June 23, 2014 Share Posted June 23, 2014 (edited) Question for you Dot Gurus. I'm going to mount a Delta Point 2 on an M&P 9mm CORE, so the dot to bore should be much less than the typical mounts used in Open. I'm going to be using MG 124 JHP and going for 1050-1100fps. What is going to be my best zero? Going to shoot Steel Challenges and local USPSA, so seldom over 35 yards. Thanks in advance ZH Edited June 23, 2014 by zhunter Link to comment Share on other sites More sharing options...
lcs Posted June 23, 2014 Share Posted June 23, 2014 I zero my C-more for 25 yards. Using a 90 degree mount is pretty much the same as a Delta Point and I'm dead on at USPSA distances. Link to comment Share on other sites More sharing options...

turkeypoker Posted November 16, 2014 Share Posted November 16, 2014 I'm also new to the open game. I think I will try 10-12 yards for zero Link to comment Share on other sites More sharing options...
skeeljc Posted November 16, 2014 Share Posted November 16, 2014 I've read and heard of people that zero the dot at 50 yards and then shoot off (Kentucky windage) for closer distances, and then some that zero at 25 and do the same for both closer and further. I've also heard of people who zero in with a 4-MOA dot element and then switch back to the 8 or 10 for actual shooting. Pros and cons? Favourite methods for zeroing? The POI changes when you change the dot. I wish it didn't. Sight in with the dot size you are going to shoot. Link to comment Share on other sites More sharing options...

Thanks in advance ZH it's actually higher than people who mount the cmore slide rides on a 90 mount. with that mount the glass starts just a couple of mm over the slide and the dot is centered very low. even milled into the slide the delta point still has the sight body (between 1/4 and 1/2 inch from memory) before the glass starts. but yes, it is lower than a traditional upright mount but still not as much as you might think. if you're shooting USPSA and SC I would suggest a zero around 20-25 yards is the best way to go. 20 is probably where I'd start.

sauza45 Posted November 17, 2014 Share Posted November 17, 2014 I zero mine at 25 yards, I run a traditional mount. After I zero at 25 I then shoot at 5, 10, 15, 20 to see where it hits. I am only about 1 inch low at 5 yards and about 1/2 inch low at 10. Everything else is dead on. Link to comment Share on other sites More sharing options...
