Grand Slam????

[Big joe]

I check into the reloading room frequently and love the info and various opinions. I have heard many of you talk about your favorite premium bullets but I rarely if ever, hear anyone mention the Speer Grand Slam. I'm curious about this bullet. The price is a little lower, technology sounds good. Have any of you tried the Grand Slam ??? If so... Let me know what you thought. By the way, I shoot a 243 Win, 270Win and a 300 Win Mag.

Thanks for your info in advance.

I bought three boxes of loaded Speer Nitrex ammo in .308 Win. with the 165 gr. grand Slam bullet. They shot quite well giving groups equal to the best handload in that very fussy rifle.

I also picked up 200 250 gr. 35 caliber Grand Slam bullets for reloading in my .35 Whelen, but have not shot any yet.
As to how they work on game, here in Arizona, one has to draw a tag in a lottery to be able to hunt. I haven't had a chance to try them on game.

I have also heard that curent Grand Slam bullets are no longer made with the hard core and softer front core, but are more like a conventional bullet. I'm not sure I like that idea. I don't think they changed it to a bonded core type bullet, but I may be way off base on that point.

probably wasn't much help, but that's my experience with them so far.

For whatever reason, Sperr bullets just don't seem to get much respect. It isn't that anybody badmouths them, but nobody sings their praises, either.

That's both weird and a shame.

They're good bullets - just as good as any others. The Grand Slam used to have a dual core, as mentioned by PJ. They poured in a molten alloy of a somewhat hard alloy, then a front core of very soft lead. I've also heard that today's Grand Slam has just a single alloy, but is still poured in molten.

I'd try a box and if your rifle likes them, I'd have no druthers about using them on game.

I think they are better than standard bullets, but I think Partitions are arguably a little bit better.

My opinions of bullets keep on evolving. Right now, my theory is that Sierras are best for target shooting, and a lot of game hunting. I think Partitions are best when you really need a little bit of an edge, such as shooting an elk with something sub 270, or when impact is likely to be above 2800 fps.

I have seen the 165gr .30cal grand slam take deer quite swiftly when fired from a .300WSM. Velocity was about 3100fps and they were very accurate also. It was by brother's rifle and load and he also did the shooting I was along and watched a doe get run from stem to stern with one she was D.O.A. Not alot of damage and complete pass through I think it was a good performance. The stores in my area just don't carry alot of them so I buy other brands but I would have no problems using them on most any game including elk or moose.

I've shot 145 gr. Grand Slams through a 7x57, and they shot
well, providing very-respectable 100 yd groups. But, just about
every spitzer or semi-spitzer that I've run across, from Hornady
to Sierra to Nosler to Barnes to non-Grand Slam Speer, has
a significantly better ballistic coefficient than the Grand Slam.

I don't typically use "premium" bullets in my deer rifles. In my
experience, using non-magnum cartridges, they just don't seem
to provide any appreciable benefit.

In my elk rifles, on the other hand, which are magnum offerings,
I use "premium" bullets exclusively. But, Nosler Partitions,
Win/CT Fail Safes, and Barnes all offer significantly better
ballistic coefficients than the Grand Slams, so I am inclined
to use one of the former unless I just can't get any of them
to shoot well. I might then consider the Grand Slam.

Does ballistic coefficient make any difference in the real world?
Not for 99% of the shots I take on deer at 200 yards or less.
But, for an elk/mule deer/antelope at 350 yds, shooting into a cross wind, it may
make the difference between holding the crosshairs on hair
or on air.

I use the 180 GS in my '06 -- it's a good bullet and does the job providing good accuracy. Guess that's the nature of us hunters and shooters, always looking and wondering if anything is greener. I'm getting ready to try both the A frame and Barnes Triple Xs out. Waidmannsheil, Dom.
