    That’s at a density altitude of 5875.

    Edit to add: That’s with 750gr Amax at 2660fps, firing due north, with coriolis factored and no spin drift. Also removed some data to make more info visible for the screenshot.

    I'm in slacker mode from May to the middle of August, so most of that is the right time of year.:clown:

    Thats great info. Thank you.

    How do you read the left column? The only way it makes sense to me is to read it to the 3rd decimal sooooo 1 inch drop at 1500? Is that right?

    Also curious when the sonic transition takes place (roughly) in its flight?

    TIA

    NO! The Left column is INCHES, NOT decimal places . The drop at 1500 yards is about SEVEN HUNDRED inches. With the charted 750 grain bullet load the round goes subsonic at about 2300 yards

    Ahhh all right, I gotcha. Kinda started seeing through that when Younggun posted his chart.

    Thanks for bringing me up to speed. And you @Younggun

    If the timing is right, I’d make it. May always has a ton of family commitments for us.

    @FireInTheWire needs to hide the UTV and lockup the vodak with the crowd that’s planning on being there.

    Probably ought to lock up all the heavy equipment, too.

    This could be fun.
    Hush!

    Hey fellas! Thanks so much for all of the info and opinions, as well as pointers based on experience.

    So my goal is hunting out to 500 yards, but I've never hunted so to me that is just a "just in case" number. I want to get into it, and get my sons involved. I come from a humble family, but not a very self sustaining minded family and I want to teach me sons how to fend for themselves.

    Second is that I want to be able to sit on a hill and pop would be "bad guys" from as far away as realistic without having to be a special forces sniper, if the world or country goes to poop. I don't intend on walking around looking for trouble, but being able to defend my homestead from far enough away that any advancements would be thought twice about.

    As to the question on where I shoot and how far, there are places in the desert (El Paso) and NM that if you pick a good spot, you can get a good 400 yards away from a back drop and pop off all day and night. Probably even further. So I can practice all I want.

    This leads to the question of wether or not I HAVE actually practiced with what I've got and the answer is NO. Long range, no. I shoot all the time but it's always out to about 100 yards and in and not for a study of wind and what not, but just to have fun and at least hit an 8" plate.

    Thanks for the link to that sale. I had no clue a 308, ar10 lower can be had for that price.

    Last, with all of the great posts, I'm still left questioning whether it would be better to have an AR10, or a bolt rifle. My inexperienced mind say an AR10 is better just in case I have to use it like a regular ar (semi auto gun fight from close proximity), but I've read that bolt guns are more accurate and better for follow ups.

    I should had added a pole for those. So what's it gonna be? Should I start with a bolt or AR10?

    You guys are the best. Thank you for educating me.
