I'm looking for a reliable source of Noslers in NSW. Any thoughts?
They should be fairly Available at all Gun shops down here mate, unless your chasing silly amounts?
depending where you wanna be in NSW, i can pre order what you need before you arrive or whatever.
Im around the Border of Vic & NSW Theres a large store here.
But i dont see much problem unless your heading rather Rural.
PM me if need be

The guy who loads my ammo because I can't fly enough of it lives in East Kurrajong. I hunt in the NT though. He hasn't been seeing a lot of Noslers, but that may just be a case of local availability. If they are in the system he will be able to order them.
I'm bringing my own .300 Win ammo and he will load 30-06 for my son and I. The Aussy airlines won't issue a Dangerous Goods permit to a minor.

I asked Marshall about these, I have a 9" twist 25 cal tube looking for long bullets. Hopefully something comes of it later this year.
G1 projectile is flat bottomed and blunt nosed. G7 is a
boat tail pointed projectile. Use the one that your bullet
looks most like and the trajectory prediction will match
better. "Applied Ballistics for Long Range Shooting" by
Bryan Litz is a great resource.

+1 to that.
The numbers are probably 10% too high: Nosler 308 200gr Accubond has a "Nolser B.C" of 0.588 G1 while its true value is 0.530...
It's not a big issue since Barnes, Nolser and Hornady BC are always 10% too high while Berger and Sierra are 100% accurate.
Remember that the 277 140gr Accubond is a death ray when fired at 3200fps from a 270 WSM and that the new 150gr Accubond LR will be ever better!
Accubonds LR won't be 25%-50% better but it might really be 10-20% better than the existing Accubonds.

Alex - I have found that some Noslers are close - a prime example is the 200gr Partition in .308", which is pretty much spot on. We looked at Bryan Litz's numbers, verified muzzle velocity with an Oehler 35P, and confirmed calculated drops out to 500 yards with actual range time. The 7mm 175gr Partition, on the other hand, is +15% off, going from a claimed .519 to .450, again confirmed in the above noted fashion.
While the ultimate responsibility lies with the person pulling the trigger, I think it would be nice to have accurate numbers because many folks (if not most) just plug numbers into a ballistic calculator and then think they can shoot accurately out to silly ranges without actually practicing and confirming performance on paper first. For example, if I looked at the "book" numbers for muzzle velocity and BC, I would have been well over 7" off at 500 yards (with a 200 yard zero). Granted at the regular ranges we shoot it hardly makes a difference, but then again the LR Accubonds aren't marketed for "regular" distances either.
I took my longest successful shot with a 270 Winchester, using the 140 Accubond
I had practiced with it right out past 600 meters, so knew exactly what the drop figures were. [real figures, not ballistic charts]
In my "hunting" rifles I have always used a similar sight-in....+3" at 100 yards. [30-30 and 38-55 excepted]
So sighted, my point-blank range on an animal is optimal for me.
The new Accubond will simply increase that PBR a bit.

I entirely agree with your point but Barnes, Hornady and Nosler only give us the 3000+ fps G1 BC of their bullets!
In fact, even Matrix Ballistics also only gives a static BC which is probably valid at 3000+ fps G1 BC.
What is required is a complete move to the proper BC (G7 for most boat tail bullets) and some SAAMI/CIP process to determine a standard BC value.
Remember that car manufacturers and governments still can't give us a realistic gas mileage for car but that any serious car magazine can easily measure the value.
I'm seriously considering building a custom 284 Win, 7 WSM or 7 RSUM chambered long range hunting rifle because of the new 7mm Accubond LR bullets alone!
