I am very new to longrange shooting but sent my Zeiss Conquest out to have target turrets put on it. Now I am wanting to order Kenton Turrets. I do my own reloading so was looking at there TTC#2 order form. Problem is I do not know the answers to most of the questions on the order from. I know I can get the velocity from a chrono. Where do I get bullet b.c from? What about barometric pressure? Sorry if this seems like an answer I should easily know.

The BC is readily available on the bullet manufacturer's web site.
Scope height can be measured (check archives).
Barometric pressure you can get by checking weather.com the day you shoot.
I'd send them the temp on the day I shot plus the average temp of the season I'm shooting. For example, if it's 50 when I sight in but usually 30 during elk hunting I'd tell them 30.
FYI I'd also tell them the altitude where I'm shooting now and the altitude where I'm going. You can't give them too much info.

Walker1,
Any chance on actually doing your own drop chart? I know they have an order form with the option of providing your own drop data. I have used software from several different manufacturers. They all get me on paper and seem to be close out to 600 yds. Beyond that, my actual performance with my rifles seem to vary from that computed from the software.
If it were me spending $100 for a Kenton turret, I would first develop a drop table at the elevation and weather conditions that I would encounter most of the time when hunting. This would serve you better than providing the velocity, BC, etc. and then hoping that they get it right. As I said before, their calculations will most likely be accurate out to about 600 yds, but after that? For my $100, I would rather be sure.

+1 on your own drop measurements. Sight in at your "zero" then shoot at 100 yd intervals holding on the center of your target each time and measure the drop from each yardage. This will give Kenton the arc of your particular bullet then they can match the turret to the different distances.
It doesn't have to be out 1000 yds. if you can not shoot that far, but I'd go to 600 yds. if possible.

After doing some more searching on the forums I have thought of that myself. I know I can shoot out to 900yrds in my shooting area. I should have started doing this earlier when the weather was colder. I figured I would zero in at 200yrds. I have the Burris Signature rings with adjusters so I can offset the scope to shoot further. If that makes since to anybody.

I have no knowledge regarding Zeiss target turrets, so I cannot comment on that. However, I would encourage you to dial up and keep track of just how many MOA it takes to hit center at 100 yard intervals, rather than just measuring the drop. Each scope tracks differently, and not each every scope that advertises 1/4 MOA actually moves your point of impact 1/4 MOA. Rather than have Kenton assume your scopes clicks equal 1/4 MOA - just do it yourself. That way you know for sure. Also be sure and use your own rangefinder, rather than relying on someone else's, or the yardage marked at the range.

I have a zeiss conquest 6.5-20x50 AO on my 340 Accumark and have Kenton Turrets. They are basically the Zeiss Factory Knobs custom engraved. I have a Speed dial one turn (18MOA) out to 900 yards. The markings are large and bright for my old dim eyes. I have taken elk out to 650 yards with them. Ziess scopes are pretty good about tracking 1/4 MOA per click.
You can try the box test and see how repeatable the return to zero is for your particular scope.
Zero your rifle dead center at 100 yards. Move up and right +5MOA then Shoot 3 rounds. Move straight down -10MOA shoot. Move left -10MOA shoot.
Move Up +10 MOA shoot. Move down and left -5MOA back to center. If your scope tracks well every group should be at the corners of a 5"x5" rectangle with its center on the bull.
If it doesn't track right, call Zeiss USA in Chester, VA and they'll fix it FOC.

azsugarbear has a good point which I did not take into consideration because my PST tracks very accurate and repeatable.
