what would the difference be between XM193 55gr and M855 62gr at say 100 200 300 meters and on Ive been told its almost no difference but I dont think so especially at longer distances any ballistic charts out there thanks I need to sight in soon |

actually it is for an acog but i never found this in the search... Im sighting in my ACOG NSN and its dead nuts my 25 meter initial sight in put 3 bullets in less than 1/2 an inch...I put them into a hole that was in the top of the carboard silhouette...i guess a hanging hole for ita and then 10 rounds inside a 3 inch shoot and see so it is less than a 3 inch group at 100 meters prob about 2 1/4 im not a sharpshooter by any means I did sight in as per trijicons manual Federal XM193 55gr ammo was used using the 300 meter mark to get it in the ballpark 16 inch barrel 1:9 twist flattop mount it put 10 bullets in a 1 inch diamond and at 100 meters put 3 within 2 1/4 inches and one flyer when the wind blew and shoot the table I was on I love this sight next time I have to look a little harder for that topic |
