New Contest Starting Now! This Target Haunts Me
Tell us about the one that got away, the flier that ruined your group, the zero that drifted, the shot you still see when you close your eyes. Winner will receive a free scope!
Some great stuff by Diver here. I personally highly rate both the 123 and 139 scenars, these are not the highest BC slickest bullets out there but man they tend to shoot accurately easily. I also use 130 berger vld but the scenars are better to me. Going to give the 140 RDF a try soon I think...
Thanks mate part of my problem was I was comparing a JBM print out with the same environmentals etc as ballistic AE thinking they are exactly the same but they are not this was throwing me off.
Once I compared a screen of non corrected data from ballistic AE with corrected data like you said...
Yer man I wasted enough ammo and barrel life to work all this stuff out!!!! I think this might be why so many have issues with "truing" which is actually scope errors that they either don't know about or have the wrong corrections in their app based on a single tall target test they may have...
Can anyone help me before I delete this app off my phone. The litz formulas for scope correction do not work on this app. If I want to put a 1% adjustment in there how the hell do you do it? For example if my scope moves 1% more than it supposed to the correction factor should be less than 1...
I'm not sure if shooting the tall target test is an accurate enough way to measure scope error when trying to get below 2%. I'd be interested to know if any members have done several tall target tests on the same scope on different days.
I think unless you are using a benchrest gun capable of...
The most truth written on this site. Recommendations of tangent theta and ZCO these cost more than my car must be lots people with very deep pockets around here!!!! The guy that came 3rd at the ELR event with his 7mm hunting rifle and SWFA scope will still wipe the floor with just about anyone...
yes it gets hotter than that here too well over 110f in American terms my point was that its ALWAYS hot 80-100F all year round no such thing as a cool weather break where mirage backs off like you guys get in the states.
no one is mentioning the weather that cannot be controlled in this (mirage/heat shimmer)? here in the tropics I shoot across flat field temps are always 80-100F in American terms with high humidity. at 700m I usually have to add between .2 and .3mils to hit steel. That is a bigger error factor...
Ok so I have being playing with JBM and I need math help. I have the 6mph worked out it moves the bullet 5moa at 1000, and 0.5 moa every hundred perfect. I cannot work out how to do the calculation if the wind is for example 9mph or 14mph or 4mph?? Is it possible to work these out in your...
Everything here is understandably US based in yards, will any of this work for those of us using MOA scope but ranges in metres?? I must admit most of this thread is way beyond me I don't honestly think I can crunch any of these calculations in my head on the firing line but I guess anything can...
Diver can you please tell what AOF means and CEP means?? I'm guessing CEP means once your group size is bigger than the target ie you gun is 1/2moa but the target is 1/4moa??
