Hi All-
I've got a great below 95 degree .308 load worked up with the following:
SMK 168gr HPBT
39.5 GR IMR 8208
2.202 OGIVE
2.80 OAL
BR2 primers
Trim 2.005
Savage Elite Precision rifle
If I shoot well, 1/3 MOA
I tried the same load with different bullets to see what would happen. The ogives on these are all over the place, so I just used 2.8 OAL. It was 110 degrees when I shot them, and the rounds were on a shaded cement bench for an hour.
I shot them clockwise (Berger first), and was trying to cool the barrel every 3 shots for 5 min, with a matress pump and a plastic hose, which didn't do much I think. These are 5 shot groups, except the SMK, which was 3. Wind was 3 MPH from the right. The Hornady seems to be great in heat. Interesting how I got 2 holes. I was shooting pretty good that day, so I guess I could conclude that the Hornady BC and shape like heat? Dunno, just thought I'd share. Good factory ammo is usually 1-2 MOA in 110+.
I get 1/3 to 3/4 MOA in extreme heat with the Hornady 75gr in my ARs as well.
