Rifle he popped a yote with the other day, Daniel Defense .308, I put a different scope on to play at distance. It's in mils, working up a dope chart yesterday. Zeroed at 100, backed off to 400. Factory Norma 147 fmj put two 400 yd shots at slightly less than an inch. Middle of afternoon, heat mirage got bad so we stopped. Chronograph is key and mine had dead batteries so we were winging it on fps, just using the info off the box. Need slight adjustment left and up to be on.

I always hesitate to adjust my scope over hitting left/right at ranges beyond 200yds. There could be a bit of wind out there pushing you.

ARs tend to lose a little steam over a bolt action of same barrel length velocity.

Good shooting rifle and a steady hand.

That’s good shooting! Will he use that rifle for deer season or any other hunts?
Ron, he said he'll deer hunt with it but with a different scope, the one he used on the yote the other day, Leupold 2.5-8x36.
I put a Burris 3-15x50 to play at long range. Friend of ours, ex Marine, has taken my son out shooting at distance. Teaching him how to use mils where he dials it up. I've gone the same route but with a different scope. All of our scopes for LR are FFP with a fine reticle. Tough to see reticle below 10x against trees. 4-5x it all but disappears.

No wind when we were shooting Monday. Little hollow protected from the wind plus plenty of trees to get a wind read if there was a wind.
In the wide open at long distance, a Kestrel gives you the wind speed and shooting solution.

Are you saying two bullets exiting a barrel, at the same velocity, one from AR, one from bolt action, the AR will drop more over distance???

That's good shooting off that bench! Following the response to above! I'm gonna mess around with a Sig Scope that bluetooth connects to my rangefinder and see how well it works. Just haven't decided if I'm gonna take a scope off one of my existing rifles or is this the reason to buy a new one? Then the dilemna what caliber!

If the gas port is before the powder reaches peak pressure you can lose a small amount of velocity. With that long of a barrel I’d say the manufacturer specs tested with a 24” or 26” barrel were what threw off the velocity #’s.

I deducted 150 fps to allow for 6" shorter barrel. 18" vs 24". Plugged in the numbers on my ballistic program, shot low. Need to up the velocity numbers on the program, see what happens.

I'm getting the Kilo 2400 ABS to play with. Bluetooth to my phone. Will be a wonderful thing as long as everything is charged or good batteries.
