The 129 ABLR going 3400 out of my 26 Nosler did considerable damage to a deer at 120 yrds through both shoulders,dropped in its tracks but needed a follow up.similar damage as the old Ballistic tips did out of my 300WM. I have a box of the 142's to try  :dunno: I know they are designed for long range but you never know what distance you will be shooting.

  I think a lot of bullets would have issues at 3400fps :chuckle: :yike:

This is the info I was going by:

http://www.longrangehunting.com/forums/f19/nosler-lr-accubonds-bc-testing-results-137554/

Quote
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.

This is accurate!!! I have the 150 LRABS all loaded up, doped and trued all they way to 1300 Yards. I am using a 9 twist barrel and the 0.291 G7 BC is good to go.

Glad they are spot on for you.  They weren't for me.  Even with an SG of 2.21.  I've stretched these out to 950 (max for where I shoot).
