There is a table on the 400 yard range.
Do you have a bipod?
You betcha...But I’ll probably lay prone...Shooting from the bench is a bit hard on peoples shoulders...
You need to put your body in-line from the rifle to your shoulder, straight back through your hip and right or left leg (as you choose to shoot), heel down and dug in...
That way the “lurch” transfers nice and easy down that line through you and to the turf...
Big bores don’t really kick, in my opinion...they kinda “lurch”...I also recommend staying off the scope with the eye...At least a good 3 inches...I have the scope setup (eye relief to about 3 inches...A good cap or even a small towel will shade that gap and give you a good sight picture for your shot...
I also recommend double hearing protection for those shooting it...plugs and muffs...Its got a nice bark to it...
One thing I do owe (and thank) T.C. on this, is he sent me down the path to aquire one of these...
It may not be as fun as a belt fed MG, or a semi-auto version...But it does get you to remember ALL the basics of marksmanship and good safety practices...
