Mil-Dot/308 Load Integration

Posted
This list contains loads that will integrate very well with a Mil-dot reticle when zeroed at 100 yards. I know there are quite a few of you that shoot the 308 near sea level when deer hunting, and have not gotten an R2...yet. Setting up with one of these loads will allow you to produce a precise shot within a couple seconds of having the range.

Hornady 150 Interbond at 2860 fps. 46 grains of Varget.

Hornady 155 Amax at 2820 fps., 45.8 grains of Varget.

Berger 168 VLD at 2760 fps., 46.5 grains of Varget.

Nosler 150 BT at 2840 fps., 45.6 grains of Varget.

Nosler 165 BT at 2780 fps., 46.8 grains of Varget.

Lapua 155 Scenar at 2760 fps., 44.6 grains of Varget.

Sierra 175 MK at 2780 fps., 50.5 Grains of H-4350.



By carefully zeroing your rifle at 100 yards, your first Mil-dot below the main crosshair should be almost dead on at 300 yards, the second dot below should be dead on at 400 yards, the third dot at 500 yards, and the fourth dot below should be dead on at 600 yards. When given a short time slice to break a quality shot, here is the trick....LEARN TO NOT CLICK!

Good luck this deer season.

What velocity and BC ranges will integrate with the mildot reticle this way?

Are there any .223 loads that will also integrate?

At 5000 ft. ASL, the 75 grain A-max at about 2,760 might work in cooler weather, as well as the 80 grain Sierra if you can get it over 2700 fps.

So anything with a velocity of 2750 to 2875 fps and a BC of .415 to .515 should fly pretty close?

Do you think you could still make the velocity requirements out of a 16 to 18” AR10 with any of the above loads?

Altitude plays a big part in which end of the velocity and which end of the BC range will work best. Your initial target trajectory should be 13.75 MOA up from 100 to 600. If you can find a bullet and powder combination that tunes on your barrel at that trajectory, near the altitude you are shooting at, you are in real good shape.

Pardon my ignorance, but what should the MOA drop be for each of the mil-dots? 13.75 for the bottom one. . .

Thanks! I want to get a mil-dot scope to put on my 300WM or 300RSAUM, but I would like to know what the set-up will be ahead of time. That way I can work on my drop charts now, and try to tune the loads to fit the dots.

Got a chance to see the effectiveness of mil-dot holdovers this morning. Ran across 3 coyotes in a neighbors field and just happened to have my .308 with me. Ranged the first and second coyotes at 530 yards, the third yote at 580 yards, and the edge of a sagebrush draw at 720 yards. My second dot down is 545 yards so I held bottom of coyote and watched the feet flip upright after recoil. I chambered round #2 and found the second coyote just standing their looking around. So I dropped Her also! First double on coyotes ever so I was feeling pretty good, only to notice coyote # 3 heading for the brushy draw I had ranged previously. My fourth dot down is 740 yards so I lined up on the edge of the draw thinking maybe the yote would give me a look before exiting the scene. Sure enough it stopped and turned back and gave me a quartering away look for about 7 to 10 seconds. I've only got a Weaver Tactical 3 X 9 scope on this gun and that coyote was looking awfully small to me about this time; and my adreanalin was starting to takeover my bodily functions!! I opted to let it go, but after thinking about it a bit would never have even had an opportunity on the third coyote if I was still ranging and clicking like I did in the past.

Thanks for the great site and all the information shared.

500 plus yards on a double with a 9 power scope is flat out superb markmanship. Way to drop the hammer mt rancher!!!!!!!!
