Yes they are known distances. Cold knows more about it . (Cold is a moderator here that shoots three gun a lot) I understand in the real world 600 yards is not that common but they throw those targets into matches with some frequency. 400 is fairly common. In Alaska the longest I have had to shoot is 250 so its not an issue up here. But I want to go down south and shoot with the big boys.

Looks pretty good, how much will these sell for?
If you look at the optics that 3gunners are using, you will rarely see exposed turrets. I think they would not only not be needed, but could be a hinderance. Exposed turrets can be bumped out of zero. Also, if you are using a turret to adjust your poi for long targets, you are adding time to the clock that you don't need. There might be times being able to adjust the elevation could be useful, but those times are so rare that it would not out weight the disadvantages, imho.
Targets at 3 gun matches are rarely much over 300 yards, and almost never past 400, although I like an occasional 400+ target to add some challenge. The toughest match I've shot is the MGM Ironman. The longest target last year (for the 3gun rifle) was about 440 yards. There were 2 longer targets, at 500 and 730, but they could be engaged with a separate rifle. Few competitors engaged the longer targets with their 3gun rifle.
The answer is to know your holdovers. A scope with some kind of bdc reticle can come in handy, but it isn't necessary. I've been using a Trijicon Accupoint TR21 1.25-4 (amber triangle on a double post) on my main match rifle the last few years, and it's pretty satisfactory, although holdover is a bit iffy at times.
That said, I'm interested in this Vortex scope. I like the looks of the scope and the reticle. I can overlook the disadvantage of exposed turrets. Could always make a 'cap' of duct tape!![]()
You can always employ a locking turrent like the S&B short dot. I signed up for Larue's match this year and the furthest targets are at 500. Curious as to how you do hold over with your TR21. I am going to have the same issue at Larue with my Swarovski. The only solution I can see is dialing in the range. I also disagree on the disadvantage of exposed turrets. I ran my GAP AR10 through a week long sniper class which involved low crawling, running and shooting from very awkward positions and never once did my scope turrent get knocked out of place on my Night Force.

Nice to hear they don't get knocked out that easily. It still bothers me on my LR scopes like the Leupold MK 4. I wish the turrets locked.
You can hold over with the TR21, but it can be a little problematic. I didn't have any trouble at 440 making my hits. There was a slight breeze from the right, so I just held off of, and slightly above, the right shoulder (from my view) and made the hits. The target was a steel plate the size and shape of the USPSA metric, so a hit anywhere was good. One thing that helps is that I zero for the longest range I can to take advantage of the 223s trajectory. This year I started sighting in 4" high at 100 yards. This lets me use a 6 oclock hold on 8" plates and other steel targets from 75 to about 250. The Accupoint triange works really well for that sighting system. I'm on at about 275. A hold near the top of a 300 yard plate gives a good hit. Much beyond that and you need to start figuring hold over.
You'll have a ball at the LaRue match, I'm sure. The 500 yard target should be a challenge. A scope with a good holdover system, like the Burris XTR, would be a good choice for that match, I think. Whatever you use, you'll need to verify your holds at the range you'll be shooting. Don't just rely on ballistic tables. A range where I shoot has a steel gong at 500 meters. That has been a big help in learning my holdovers.
You should go to the Larue match. Sounds like a blast to me.

Although I'm retired, I'm having to re-join the ranks of the working stiffs, so I can't make it to all the matches I'd like. I'll be doing good just to make it to Ironman this year. That match is "the most fun you can have with your guns on"!
Another good match you might look into is the NW Challenge at Albany, OR. Sponsored by R&R Racing. I haven't seen any info on it so far this year, so not sure of it's status.
