Hey Guys I have been drawn for SD mule deer, I am going to take my 338 LM and I need to get things in order first order of buisness is getting a reliable ballistics program however I may already have it. I currently have Bullet Flight on my Iphone and back in June when I was prairie doggin up in S.D. where I will be mulie hunting I could not get my drops correct. @ 950 yards I could not get the program to give me the right dope. I tried to adjust velocity, temp, alt, to get me there and I just couldn't get it right. My dad could take his 6.5 and dail right up and smack the target no problem, everytime I would dial up using Bulletflight I was 6 or 8 clicks off. I am thinking about Exbal and putting it on a pocket p.c. Do you guys recommend Exbal or something similar over Bullet Flight or Iphone based apps. I wanna get a very reliable program and start to practice for my upcoming hunt. The owner of the lodge has watched my father and I shoot steel out to a 1000 when we have been out their for prarie dogs, and promised me a booner if I can shoot like that when out in the field.
