Len,
My barrel is 30".
After reading Wayne's post with his weighing 116.1gr, I went back to look at mine, mine was also 116.1gr, not sure where I came up with 117gr. Maybe I figured when the necks lengthened back out to 2.720" they would be 117gr. They were all trimmed to 2.690" after fire forming and 116.1gr is wrote right on the side of them.
Wayne's case has a bit more capacity above the shoulder because his has a 35 degree and mine has a 40 degree, mine is a tiny bit larger in diameter below the shoulder though (.570"), which is why I think we have basically the same capacity in the two.
210 Bergers blew holes right through my 3/8" steel plate at 600 yards yesterday, and almost through the 1/2" plate. They're going 3200 fps. I've got a bunch of welding up to do on 'em now!
Going back out to try 800 and 1000 yards today, a few shots before it's dark anyway.
DB,
The water left in the case
WILL add about 2-3gr in my experience. Even if you tap it out real well it will always weigh over by this amount. I weigh them first, primer upside down, fire formed, drop of dish soap in the eye drop bottle, top it off until the water is flush to the top. No big bubble on top, just flush so you can barely see the water looking at it across the case mouth from the side.
Tap every bit of water out of the case afterward to see what the difference in dry weight verses wet weight is.
Now there's a difference in the way your rifle is throated for long bullets, which could give an even bigger edge to the shorter fatter Lapua case design, that is if your magazine box doesn't allow the big bullets to be seated out in the Ultra's, it can using the Lapua case. The neck on the Ultra is real short, which also eats up more capacity when seating bullets when a chamber is improperly throated for them. If each is throated properly, the mag box will still limit the Ultra or Weatherby/Rigby case where as the Lapua will gain an edge on it as it won't have to be seated any deeper.
Loaded OAL at land contact for the 30-338 Lapua IMP with:
210 JLK....... 3.818"
210 Berger.... 3.741"
240 SMK....... 3.694"
200 Accubond.. 3.769"
178 A-Max..... 3.701"
I think I'm going to have to end this shooting with Michael, he pretty much wipped my *** with his awesome shooting 308win yesterday! When I shot his 308, I found out his secret! It's a freakin 1 ton trigger pull!!!
Must be all of 10lbs anyway. He stacks 'em in there with it though, 3 different bullets too! You don't ever want to be in this guys sights!
