7 re mag and 150 g bullets

Three bullets with 68 grains of RL-26 proved to be very good. Nosler AccuBond Long Range, Swift Scirocco II and Hornady ELD-X each made a half inch group @ 100 yards. Seat the bullets so you have a maximum length to feed from a full magazine.
RL-26 is extremely hard to find now, H-1000 is a great substitute for -26.
 
I have taken two mule deer bucks and one cow elk with a 7mm Rem Mag and 160 grain Accubonds, one shot each.

I think the 150 grain AccuBond (only 10 grains lighter) would be a great all-around load frankly. Something in the 4350-4831 burn rate range would work famously. I’ve not found the 7mm Rem Mag to be difficult to get to shoot well!
 
Yes, I have used 150 gr, BT's in the 7mm RM with Reloder 23 and achieved excellent accuracy and great terminal performance on whitetail deer.

I have also use 150 gr. ABLR's in the 7mm WSM with Reloder 23 with similar accuracy and terminal performance on whitetail deer.

During fire forming I had some great groups with the 154 gr. Hornady interlocks.
 
Sorry, I only used 160 gr AccuBonds and 165 gr SGKs (Federal Premium ammunition) in the 7mm Rem Mag. Both worked very well.

As I have chosen to use the 160 gr bullets in my 7MM STW, I am going to use the 150 gr Ballistic Tips and AccuBonds in my 280 Rem.
QuickLoad shows that I should be able to achieve 3000 to 3060 fps with a variety of powders, which is approx. 100-180 fps slower than the same bullet in the 7mm Rem Mag.

With a max velocity according to Nosler's Reloading Guide of 3248 with the max load of IMR-4350, it should perform well on game from your 7mm.
 
I have used the 150NBT's extensively in the 7mmRM using 64 grains of RL22. It is a great deer bullet and was very easy to get to shoot well. I never caught one, they always exited on red deer and smaller game. If that was the only bullet I had available to me for that cartridge, I would be a happy man.
