Hey everyone. I got a question for y'all. I'm running a pulsar xq38 lrf on a DD M4A1 .223. I zeroed it in at 50yds and it's a tack driver. At 20yds it shoots 1" low. At 100yds 1.5" high. At 150yds 3" high. At 200tds 4"high. And at 225yds 6"high. The inches are all estimated, yardages are from the built in range finder. So my question is is it normal to have to holdunder with yardage increase? It's been awhile since using glass and can't remember. Also at each yardage I did 3 shot groups and each group the shots were less than 1\2 inch apart.
Thanks
Jack
Ok so I finally got around to taking a picture of my issue. The shots in blue are at 50yds and the red at 100yds. Shooting a DD M4A1 in .223 with a 1:8 twist. Ammo is tulammo 75gr HP. Thermal is a pulsar xq38LRF with latest firmware. View attachment 7872
In post #1 you detail one scenario. The pic shows us to distances shot, not the others listed in your scenario from your original post. Do you have a pic showing those POIs described, or are you simply calculating those elevation increases based upon your measurements of fifty and one hundred yards (shown in the pic)?

Sorry I just did those distances today, 50 and 100yds. No I did not calculate anything based off of my 50 and 100yd groups. I will try to do those other distances here in a few. Just kill some hogs so I'll try to take some more shots here in a few from the 150,200 and 225yds
