I tried the older Grand Slams in two rifles, which if my memory serves me correctly were a 7 x 57 and a .270. In both cases the accuracy was pathetic, even for this not-so-accurate shooter. Those two experiences turned me off the idea of using them on game, and I have not done so.
This topic has come up before, and a lot of very experienced hunters and shooters DO like the Grand Slams, and HAVE had good accuracy and good performance from them. I am thinking about fellows whose opinions I respect and who (I believe) really HAVE DONE what they claim to have done. (Both on this current thread and the previous ones.) Sometimes on the forums there is a bit of, shall we say, nose-stretching, and I guess I discount a lot of what I read here and elsewhere on the Net. But if a whole bunch of experienced guys say that the Grand Slam is their "go-to" bullet for hunting, I am inclined to believe them, even if I am not going to use this bullet myself.
Chrysler vs Ford vs GM, methinks.........I drive Fords and shoot Noslers........
