Thread: Velocity loss in short barrel 308

I have the SI chrono coming to me next and once I have finished with it can send it south to him @Gibo

Oops just realised he is up north. So ignore above

eg look at bottom 5
say zeroed for 190-245 will be hold dead on to(less than 4" low untill)230-285 and hold 12" over at300-370

so I would try the 303 figures and wiggle your height at 100 yards till it suits what you intend to do...
pointblank online on www.huntingnut will allow you to play with your numbers and via the bullet curve picture SEE what it should be doing....
yip you will have to validate by shooting a couple of groups out further but by using these two things as A STARTING POINT ,you should be on the money reasonably easily
