I finally found some 150 gr AccuBonds, now I need some load data. Nosler doesn’t list Big Game in their data, and that’s my fav, so I’m hoping someone has some data. I have plenty of Hunter, too, which delivers the highest velocity of the powders listed by Nosler.

If I push it hard, I can get a 150 LRAB going 2700 fps out of the 20" barrel of my 700Ti
 
Not the AB, but 45.5 got the Lapua Scenar 2710 ave from a 22” . That’s right up against max in my rifle.

Don't have the 150 AccuBond in my QL bullet profile, but I'd feel comfy using the BT data to work up with.
 
We use the 150g NBTs in the Wife's Kimber 22" mountain rifle with RL17 at 46.5g I believe, for 2825fps and 1/2-3/4 MOA. I know it's not the AB, but it's pretty close enough anyway.
 
If I push it hard, I can get a 150 LRAB going 2700 fps out of the 20" barrel of my 700Ti
Just out of curiosity, what kind of accuracy are you getting with that 150 gr. ABLR? I've tried it in three 7x57 rifles and a .280 Remington and so far accuracy has not been good. I should say just patterns, not groups.

I have a lot more Hunter than BG, I’ll give it a go.

I get 2780 with 150 ELDX and superb accuracy, BG powder.

Interesting that Nosler’s max is of Hunter is 49.5, which indicates a dangerous load.

Thanks SJB.

As with both, it is just a guide to get you started. I pay more attention to the speed and pressure than pure charge weight. Brass difference and gun difference seems to make more difference in the actual speed than the listed charge weights.

Case in point is Nosler's 130 data for a 270. I haven't ever had a 270 that'll come close to 3100 with 59 grains of any variety of 130's and H4831.
