I don't think it has quite the accuracy of the GD 503 but it is more than sufficient for 600 and 1000 yds. I use a +-.005 Gr. a total of .01 and the 120i will do .02Gr. and i think that is all that is needed……..jimJefferson said:johara1 said:If you can't get a GD 503 invest in a A&D FX 120i for half the money ……. magnetic force registration also ………. jim
