Brent,
We estimate using a standard model. The BC will be calculated from tests conducted by Groove Bullets from actual shooting.

Ahhhh, that's all?
Can you answer the others too???
It's still not clear what the "standard" in your statements actually refers to.

Brent,
We use a standard G model. Until we test the bullets we won't really know for sure. I can't answer without data.

LeMay,
We don't have load data for a 338 Lapua. I would suggest asking on forums.
You can obtain the 206gr EXP Groove Bullet through the web site or print out the mail in order form and mail it in with a check.

I don't know how right I am on this, but he (Shaky) could also have a very high Sectional Density. The PRL bullets are like that too. I read that when the Sectional Density goes up so does the B.C.
Just my thoughs.

wasn't there a round called the 300 peagus(i know i spelled that wrong) a few years ago made on the a-square hannibal action that was supposed to be the fastest 30 cal.

Yes there was, but the .30-378 and 7.82 Warbird are still a little faster.

Nighthawk, the only way to increase SD for a given caliber is to make the bullets heavier. That's what PRL does/did by using Tungsten Powder--make very heavy bullets for the caliber.

But it sounded good though right??
Hi,
I missed this thread! I asked the same question in another forum.
I am building a 30 cal for 1000 yards and the main problem is wind. A mate is using .338WinMag necked down to 30 cal and I was thinking of nekcing down my .338LM. But we are shooting only 155gr. What works best 30cal using 155gr -- wind?
Cheers.

The 240 SMK. Why use 155's for 1000 yds?
