Ok, I just bought a box of 165 grain Speer Grand Slams to try in my .30-06. I have the Speer #12 Manual and it states a starting load of 54 grains, and a max load of 58 grains. I know they have a new one out, and it seems that EVERY manufacturer that comes out with an updated manual changes the charges. Could someone double check this for me with a #13 manual. I am sure that 55 or 56 grains of IMR 4350 should be safe, as I am shooting a Sierra Gameking (165) right now with 55 grains of 4350. I have tried a Corelokt (my grandpa's handloads) and the Gameking thus far, and just want to try something new. Give me something to compare. I have also tried other powders, and 4350 seems to be the best for my gun.

Go for it Charlie.....the load is OK...I'd start with 53 grains and work up from there.....and I sure hope you have better luck with accuracy from ther Grand Slams than I have.

Vapodog,
I was thinking of trying the grand slams...what kind of problems did you have with them??

I've bought Grand Slams for 25, 27, 30 and .338 cals and tested them in my guns for hunting loads and have never had therm shoot good. A friend has had the same experience.

I think they'll work fine for most hunting but 2.5" groups just don't trip my trigger. I've had good luck with other premium bullets such as A-Frames and Northforks and even Noslers Accubonds. I assume Hornady's innerbonds are good too but just never been successful with the Grand Slams.

I too have never had luck with grand slams. Best I could do is 2.5" groups out of my 300RUM with 180gr.

I noticed that when weighing the .30 cal Grand Slams on my scale, that they varied as much as 3 grains from bullet to bullet in a lot of 50.
My groups at 100 yards were about 2"
