Had an opportunity today to play with the ballistic app on my phone, a laser range finder and a 300wm with an accurate 208gr load on a piece of ground that disappeared into the distance!
Have never really been able to dial for distances as I was struggling to get matching figures for the data I had for the load
managed to get a good average MV
BC is known
rifle is very accurate (pic is 5 shots at 130yds)
Drop was always a bit more than the app indicated only proven at one distance past 100 yds by 0.5 MOA at 200 yds
have not managed to test it out past that until today
relatively new to the world of dialling and ranging.
having adjusted a 200yd setting and shot a stag this afternoon I found a perfect spot with lots of targets with the slight breeze right behind me
first one was a burn bank, solid mud with a good 6ft of water in front to show any error.
spot on the bank was a perfect aiming point
ranged at 358yds
app said 5 MOA
first shot landed low by a smidge and just hit the water
adjusted to 5.5 and smacked it!!
i managed to tweak the zero range slightly and the three known drops at 100, 200 and 350 all lined up.
time to test the app.
rock face with a white spot on it , ranged at 480yds
app said 9.5 moa
even with the recoil at that range you have plenty of time to get a steady sight picture and see the impact
dust and debris bang on target indicated a clean hit!
impact noise arrived a second or so later!
We're to need more space to play tomorrow!
