Just for the heck of it I took one of my new 150 gr LR Accubonds and compared it to a 140 gr BT and was surprised that the length was not all that much more. I'm running a 24" Hart 1-9 so twist rates should be absolutely fine. Can't wait to load up these new Accubonds with some VV 165. These new Accubond's (at least my 150's) have a very high BC (claimed 611 G1).

I'll wait for Litz's BC # on the ABLR. I'd bet it's well below 0.600

So far, I haven't gotten my Brux 7RM to shoot 150 ABLR's as well as it does 168 gr. VLD's. But, I haven't worked with them as much as I have with Bergers.
What's the consensus on ABLR accuracy?
Any tricks I need to know about?

He's flushed them out already...

.576 vs. .611...
Seems Nosler got a bit ambitious with their B.C. numbers...
Seems less of a spread between Nosler and Litz for the 6.5mm 129 ABLR, .553 vs. .561, or 6% with the 7mm, 1.4% with the 6.5.

The 168 is sleeker than the 175... go figure that out.

A Nosler tech told me that the ABLR's shoot best when jumped about thirty thous.

Thanks, Lefty.
I'll try .030" and see if they shoot any better. This gun has shot 168 Bergers around quarter inch at a hundred. I was hoping for at least half inch with the ABLR's, just haven't yet found the magic load.
This gun also likes 180 Hunting VLD's and 175 Partitions.

From that chart, it does appear that Nosler was a little ambitious with their BC figures . It is still sleeker that teir standard BT and their Combined Technology BT 150 gr with their claimed BC of .493 and being an Accubond, I'll assume quite bit tougher.

Noticed something strange, to me anyway and I'm sure you guys with way, way more ballistic knowledge can answer this, but that chart also lists the .284 168 gr ABLR as having a very, very slightly higher BC that the 175 ABLR with the same twist rates for both bullets. Anyone see this before or is it just a slightly different profile that makes the lighter (probably shorter too) ABLR slipperier that it's 175 gr brother. Has Mr. Litz tested the AMAX (.284 162 gr in particular) to see their actual G1 figures, or are most bullet makers optimistically inflated. I'm only asking this as it probably would have been smarter (realistic) for me to have compared the ABLR 168 gr. to the 162 gr. AMAX . It looks like Mr. Litz's testing shows the 168 gr ABLR to be almost dead on.

I got 150 and 175 ABLR's, 168's are currently not available.
Judging by the numbers, the 168 may be the pick of the litter, of course depending on how they shoot.
Right now, my best 7RM load is with 168 Hunting VLD's. I just got some Hybrids to try.

Remember as well that Bryan is not shooting your gun in your conditions. You may do better, or you may do worse. Some guys taking LRAB out to 1000 and beyond agree with Nosler's numbers. There are many variables that could account for why they would get those results vs Bryan's. I think the only way to find out how they'll work in a particular gun is to get some and shoot them.
