I need load data for Speer grand slams

[12bhunting]

DSH had a partial box of .284 145gr grand slams cheap. So I get to play with bullets. I'm hoping I can run 3,000 + fps using imr 4064 or imr 4831. Every book I have lists 140 & 150gr, but not 145. Common sense tells me to split the difference in max and min loads, but that's not the safe way or the correct way. But if one of you fine gentleman have the actual data that would be good...


Also picked up half a box of SGK .284 175gr for $4, man I like that place..

I found a load for speer 145 in Hodgdons #19, but it only list using 77gr 5010 @ 3100fps

Good to know that speer data is availible for asking. I don't have that one. :goodjob:
I have lyman #49, sierra, hornady, and lee load data.

Got a Speer book too, soon as I get back from freakin jury duty I'll check it out and see if it is different.

Speer 14 has more data than 10, however 10 does have info on 4064 10 is the '79 edition. LOL

.284 grand slams in 145gr.
Before the barrel swap it would shoot 160gr SGK with unbelievable accuracy. But the new barrel will not group them better than 1 1/2-2". Well let me rephrase that, it does not seem to like them pushed by imr 4831, another powder choice might have different results. Now the good news is 150gr core lokt store bought grouped at 1 1/4", so I always have a back up.
