If your not getting it on paper at 100 yards move back to 50 yards and zero it at that point and then move to 100 yards. You can get a trajectory table from the manufacturer of your ammunition in fact most are printed on the ammunition box. Bear in mind a lot of factory ammo is underloaded and doesn't match advertised velocity. This is just a guideline..too many variables in place to predict point of impact at ranges beyond 200 yards. Temperature,Humidity, Weather, condition of firearm etc etc. Generally using any high velocity magnum with pointed bullets if you are 1.5-2.0 at 100 yards you'll be within a couple of inches of point of aim at 200 but no guarantee on that either. As other's have suggested you must shoot targets at the distances you plan on shooting game to deteremine POI.

In my 7 rem mag using 150NBT's I am around -1/4" at 25, + 2 1/4" at 100 and zero at 250.
To your question at +2" at 25 I would assume you'll be around 10" high at 100, like mentioned this is just a guess. I would bring the POI down to around the bull at 25 yards(be 32 clicks down if your using a scope that is 1 click =1/4" at 100) , this will get you on the paper at 100 for sure. Then fine tune at 100 yards for your desired Zero/range.

Most of my rifles that hit dead on at 100 yards hit about 1 1/2 low at 25 yards. Be sure to fire a round or so at the desired range to be sure.

I went on an elk this fall in Alberta and the outfitter told me most elk were shot within 60 yds. due to the thick cover and the rut. My 35 Whelen had been sighted for a 200 yd zero and I was curious to see where it shot at 25 and 50 yds. Surprised me to see that the bullet was right in the bullseye at both 25 and 50 yds. I wouldn't be surprised to see the same results with the 7 mag.
