T3X CTR sight-in
I was able to do a little sighting-in with my new T3X CTR .308. I put a Zeiss Conquest HD5 3x15x42 on. Even though we had a 10-15 mph x-wind, I was able to get some pretty nice groups at 200 yards. Not sure if this picture will post or not. If it doesn't, I'll play around with it a bit more. Bottom group is with Hornady 165 gr. SST factory load. Top group is handload using 44 grains of Varget and 165 Nosler Accubond. Using a 200 yard zero, it hits 2″ high at 100 yards, and just for laughs, I shot it at 50 yards with two different loads, and put the two bullets through the same hole about 1/4″ above the bulls eye.

Nice group, how do you like the zeiss optic?

Nice group, how do you like the zeiss optic?
This is really the first time I did any shooting over 100 yards. I have the Rapid Z 600 reticle, and to get correct bullet drop using their yardage marks, the scope needs to be zeroed at 200 yards. I have yet to shoot over 200 yards. Our range only goes to 300 yards, so when I get some free time, I plan on seeing how it shoots at 300. Using their computer program, it says I need to have the scope power on 11x, for the range marks to line up with bullet drop at 300/400/500/600.

First I must say I am not personally familiar with your zeiss optic. I would rely on distance and calculation with coresponding click up or down vs bdc. But if you trial your rifle at 100,200,and300 you can dial in your scope pretty well

One thing i can add that will help make your setup more accurate…I have years of experience with BDC scopes. Verify and adjust your scope at a longer range then 200yrds, …meaning…
Your BDC will never be as accurate as a “long range” click dial MOA scope. It could always be off by a multiplying factor of inches as you increase shooting ranges from 100 – 200 – 300 – 400 – 500 yrds…so what is zeroed at 100 yrds maybe be off as much at 12″ or more at 400 or 500 yrds when you keep multiplying the degree or error/difference in the BDC reticle and your load.
I have shot Nikon BDC scopes for years and we always sighted in at 400-500yrds after you get the gun grouping well at 100 or 200 yrds…once you establish a zero at 100 or 200yrds re-adjust your scope so you are hitting centre on targets at longer ranges…this will slightly shift your previous zero point but it will even out the errors / difference at multiple ranges and make the BDC more accurate. This may change your POI 1-2″ at 100 / 200yrds, something easy to compensate for and it will make the combo more accurate at extend ranges.
I hope I explained this well enough so you understand…

I fully understand what your getting at. I don't plan on shooting game any further than 300-400 yards. I would like to play around with steel targets at longer distances though. There is an option to fine tune the reticle at longer distances, which should suffice for what I plan on using it for.
