All,
I have been messing around with 308 lately. I was initially working with 130 class monos trying to run them fast. In my particular rifle, I could not get them to group.
So I just went the other direction, if I cannot get high velocity, I'll get ridiculously high bc. Granted, this is all just an exercise on paper currently. Meaning, plugging values into a bc calculator and seeing velocity, drift and energy numbers at extended range. Game performance is completely theoretical other than one YouTube video of one animal from a guy in New Zealand.
Important, I bought some Alpha 308 smaller primer brass. So I am loading about 1.5 grains over max Hodgon load data here. I'm getting away with that, anything more and I start seeing pressure signs if I torture test the load (fast 10 shot strings). Definitely do not try this with soft brass (Cough….Hornady).
Here is what I came up with:
212 ELDX at 2,517 fps. The 10 shot SD is 6.5 and the ES is 17 fps. I'm using Varget. Staball Match was a little more accurate but Varget was lower pressure. By the way, Staball Match is top shelf stuff. You should try it.
Oh, it's a 20 inch proof barrel. COAL is 2.801.
I'm printing one ragged hole groups with the above numbers. Again, you ain't gonna get there with ****** brass so don't try.
On paper, this is an elk load to 700 yards.
Do you guys think it will actually perform? Do I take this on an elk hunt?
**edit**
I don't actually intend to shoot an elk at 700 yards. I'm capping myself at around 500 yards. If I were to try at 700 yards, I would take my 300 PRC.
