338 Lapua Magnum

Disagree. Berger's calculator gives SG 1.52 with the 285 bullet parameters, 12-twist, 2700 fps, altitude 4000 feet, temp 59 degrees.

If he's at sea level and it's cold, he may have marginal stability, but I've shot bullets with marginal stability and they performed fine. My 12 twist 375 barrel had basically this same SG for the 390 a-tip and it shot lights out.

So it may be worth a try.

Except he said that his rifle didn’t like the 285 bullet. Whether that’s from testing or some other opinion is what matters.

Take a couple zeros off that altitude and that's right where I'm at.

We shot some of the factory hornady 285 stuff and the rifle didn't care for it. How it would do with handloads, only one way to find out. My brother only bought 100 of the bergers to try so he'll be out of them pretty quick. I might get a box of the 285 eldm for him to try.

When he bought the rifle he bought a case of the prime 300gr ammo. We must be on the ragged edge for marginal stability for that one. We've shot it some days and it'll shoot ¾ moa. Other days it's 3 moa. Still made round holes at 300 yards though. Maybe we should give the 285 a try.

It loves a 250 smk. Cheap s&b loaded with them was one ragged hole at 100. At $2 a shot, he should have cleaned the lgs out on that stuff.
 
Anyone have a hookup on 300gr bergers? Mile High my usual go to is out of stock, everywhere I look seems to be out of stock too. I have a match coming up 6/1
 
gunbroker has some.. 250 count. $$$
but with the handle of 10k a day.... that's bubble gum money ;)
