I'm gonna step back into this pit of shit.
I'll start with telling you what I've been doing.
Lately, I've taken to setting up and shooting a very lightweight 7 Remington Magnum.
The length of pull is 1-1/4" too short for me. It has no cheek piece to rest my noggin on. It has the open, swept back grip that all of the plastic stocked Remingtons came with.
It weighs 7-1/2# loaded.
I'm launching 162 ELDMs at just under 3000fps velocity.
No matter how well I get behind the rifle, it will come up some and disturb the sight picture.
Impacts at 100 yards are tough to spot. From 200+, it gets easier and easier. The pig at 517yds is super easy to spot impact. The plates at 800 can be spotted and trace is also easy to watch.
My recommendation to you?
Firstly, you need to learn to get PROPERLY set up behind your rifle.
Whether you're shooting steel, paper or speedgoats, the info you're presenting says a lot about your form.
It's terrible.
Get your mind off of the mathematics of shooting and focus on the basic principles of good marksmanship.
Learn to square up behind the rifle and practice watching trace and spotting impacts.
Don't worry about measuring or converting anything. Just learn how to shoot first.
If you want to learn to make corrections, it's really simple. Go to the range and setup directly behind a buddy and use a scope or spotter with a reticle that matches your buddie's reticle.
Hint: it won't matter if it's MIL or MOA as long as it matches his optic.
Spend a couple of hours spotting and using that ruler on the reticle to call the corrections to your buddy.
If the light doesn't come on, then I suggest taking up golf or drafting.
If you insist on doing mathematical gymnastics then we're never going to be able to help you.
Here's an image of a reticle with two different impact points. (Sorry the color blotches are big, this was done on my phone)
Let's get the consensus on what correction the shooter needs for center impact.
Green first.
Red second.
