Title: ballistic program on the phone
Post by: Jamieb on September 16, 2010, 06:50:40 PM: I've been playing with a (new to me) 375RUM/ 260gr accubonds lately.
Pretty much done with load work up, the 260's are running right at 3000fps with 101 gr of H-4831.
Tonight I was thinking that I might go up in the hill and stretch the range out this weekend so I went to JBM (http://JBM) to print a drop chart out.
When I was printing out the chart I got a idea, my wife bought me this Fancy blackberry cell phone with unlimited web so I checked and you can get on JBM with the phone. You'd have to have cell service but it will be fun to play with in the field, especially for wind drift.
I've been using JBM for my drop charts out over 12000 yards for years, if you plug in the correct numbers it's pretty close and close enough to get on paper way out there so you can fine tune a drop chart.
I just read what I typed and I am a gun geek :P

i just ordered a 375 ruger #1, so i plan on using the app again for much longer range. :IBCOOL:
