Opinions please of above bullet---reliability and accuracy.

I haven't shot anything with them, but they are accurate and appear well constructed.

None of the grand slams I used were tack drivers, but there's nothing wrong with MoA accuracy.
The 285gr out of my 375 Weatherby performed very well on Water buffalo here, the 260gr Accubond out penetrates them slightly, but penetration is still fantastic.
Never recovered one from a deer, so performance was stellar.

Cheers.

I've used GS on Alaskan brown bears to black bears and the larger african game.Always good penetration and accuracy with 80 grains of ww 760 powder winchester primers and cases,bullets seated to 3.560.

I've only used the 300GS and that was almost 15 years ago. At that time they were fairly soft up front giving very good expansion but lacking in penetration. My PH said they would be excellent lion bullets.

Ive used them on one Cape buffalo and 3 or 4 elk in my .375 and they proved very accurate in two guns I had that I tried them in..They performed like any other of todays super premium bullets, good expansion and penetration, usually stopping on the off side skin of a cape buffalo shot broadside and gave me pass threws on elk, one of which was going away and the bullet went in behind the last rib and exited behind the opposite shoulder..I gave 6 boxes to the PH I was booking for and he liked them in his 375 on buffalo, Lion and Leopard, plus he used them on all the Pg for camp meat...

That said, Im still a Nosler partition or Accubond fan given my druthers.

Thanx for the replies----very helpful !

My buddy and I used the 285s in my 380PDK wildcat. Driven around 2600. Side by side against the 260 Accubond on hogs in TX. In both rifles the Accubond gave better accuracy. In our "opinion" gave better killing performance. The 260 is now the only thing we shoot in those rifles.

The 285 gr. Speer Grand Slam was not designed for hogs, the softer Accubond or just a Sierra is all one needs on hogs..I shot many hogs with a 222...Save those Grand Slams for elk and Moose, or for your first shot on cape buffalo, followed by solids..
