I have always used Noslers (partitions and accubonds) in my 7mm Mag but they are getting really hard to find. However I do know where I can get 160 gr Sierra Grand Slams for $21.00 a box and was thinking about giving them a try. I have never loaded Sierras of any sort and am looking for opinions on them for mule deer and elk to see if it is worth my time to get a couple of boxes. I have a lot of IMR 4831 on hand.
Grand slams are made by Speer. Is that what you are asking about?
Yeah. That's what I get when I post something before I have enough coffee in my system.
Ha ha. I hear that.. So if you are asking about the Speer grand slam, it is a great bullet. Works very well on deer and even elk. My good gunsmith buddy only used the 130gr grand slam in his 270 for elk hunting and he says, "he's never lost an elk". Its funny because I asked him once why he didn't use a 150gr grand slam in his 270 and he said because the 130 always worked so well, no need to switch.. Now, I'm still not sure if you are asking about Speer's or Sierra gamekings? However, either bullet will work well on elk out of your 7mm... Also at $21/box, you are doing very well. I'd buy all I could get my hands on at that price..
