Ok, that's what I was curious about is the velocity required for the LRAB. At what range does your load drop below 1300fps?
I shoot the 95gn VLD's out of my .243 and killed alot of coyotes at various ranges. My sisters and nephew have killed multiple deer with them as well. I can honestly say the VLD's do act funky at close range. I have shot coyotes at 150 yards or so with no exits but also had others at the same range with baseball sized exits. Deer wise my sister killed a buck at 520 yards (perfect heart shot) that the bullet had fragments that almost exited the offside shoulder. I killed my spring bear with the same load at just under 300 (if I remember right) and had an exit on the 1st shot and followed up on a quartered too shot that bang flopped it. (No exit) All that being said, the consistency of the Bergers are 2nd to none. I just purchased a Sendero in 7mag and have 168gn VLD's on the way. This will be my bear gun ONLY so my plan is to load some Accubonds or Barnes to keep on hand for that one time the bear shows up under 200 or so. Donno guess I will see.

I played with the 105gr in my .243 this fall and have been very pleased so far. I actually got an exit on my montana buck which suprized me. Internal damage was epic! Those things dump everything they've got inside that body cavity.

I'm right at carps numbers. I hit the 1300 mark right around 1150 yards @ my shooting spot here at home. Change elevation and temp and that number also changes.
500. It's a 9 twist which is a bit slow for that big 105 Grainer so I had to push them pretty darn hard to get good stabilization but they shoot well. I just needed them out of the land and stuffed to the gills with powder and it shot good.

I just needed them out of the land and stuffed to the gills with powder and it shot good. Mine is a factory heavy barrel Rem 1.9.25 but has a custom chamber job and it shoots the 95's extremely well. Never tried the 105's. The 95's are at 3136fps. I'm assuming you mean you had to get them seated into the lands?
As you can see, the actual BC's can be quite close; within 1-8% of advertised if they're properly stabilized. If they're not properly stabilized (which you might not know according to groups), the BC can be 10-12% lower than advertised. The LR AB's are well designed (low drag) bullets. One reality of long/low drag bullets is they typically require faster than conventional twist rates to stabilize. However Nosler doesn't provide recommended 'specialty' twist rates for these bullets (at least not that I could find) so users are left to assume that standard twist rates will work.For example, the .270 caliber 150 grain LRAB fired from a 1:10" twist 270 Winchester only produced an SG (stability factor) of 1.19 under the conditions of the test. This low stability resulted in a G7 BC of 0.278, which is 12% below the advertised value of .317. Note that groups were good at this stability level. However, in order to achieve the highest BC, you need to generate a stability factor of at least 1.5*. Retesting the bullet in a 1:7" twist 270 Winchester produced an SG of 2.31, and a BC that's 4% higher (0.291).It's the same story with the 7mm 168 grain. Fired from a 'standard' 1:9" twist 7mm Remington Magnum, the stability factor was 1.33, and the BC was 10% less than advertised. Same bullet fired from a 1:7" twist .284 Winchester produced an SG of 2.19, and a BC that's 4% higher, and within 6% of the advertised BC.
