Have reloaded it and used it for a few years in my .270 win. Many shooters absolutely refuse to allow this bullet to have the honor of a "premium bullet" title. I think it's an excellent bullet for hunting any big game in N. America, provided you select the appropriate caliber for what you hunt.

A very good bullet. I've loaded many a Speer. I'd still be using them if my new favorite rifles could shoot them to satisfy me.

Never had a problem from My old Brit .303 with them loaded up in the mix...Deer dont know if its a hornady or a speer...They just know all of a sudden they gots them a big ole hole a leakin Thumbs up And COntrary to popular belief them 145's would be just dandy as well....139 grain hornady interlocks outta my 7mm.08 Blast a smackdown on deer sized game so Id be willing to guess that 145 grainers from that 7mm mag will do the trick just fine Thumbs up

GS

The GS is not a prem bullet, performs like a conventional bullet, the 338 Win 250 gr perform a little better, but the .308 bullets perform no different than the Speer Mag Tip.

For the 7mm Mag the 160gr Nosler Accubond and Reloader 22 powder.

Actually the Grand Slam was intriduced as a premium bullet. It has two cores in it, a hard back core and a softer front core and a thicker jacket. They are locked together with a groove and they origionally had the mag tip design. When they came out, about the only other premium bullets around were the Nosler Partition and the Barnes bullet's. They were quite a bit more expensive than the Speer Hot Cores and my luck with the Hot Cores was such that I felt no need to give them up. The biggest improvement I saw in tha G.S. was the mag tip. Speer also started making a Hot Core mag tip about then.

Those not familuar with the mag tip, it is similar to the core lock in that the tip is rounded just past the jacket. Little exposed tip. Speers claim was that the tip melted anyway soon after leaving the barrel and they even had a ohoto of a bullet in flight to proove it. I believe that is true because at that time Vernon Speer had full control of the company and he cared about his product and his customers faith much more than OMARK did after they bought Speer out. I don't use Speers simply because of that.

GS

The GS in the lower cal........perform the same as the Speer Mag Tip bullets.........pent. was the same.........diffeerence occured only at the 338/250 level and above.

For the 7mm Mag the Nosler 160 AB or Part and The Barnes 160 TSX are excellent bullets teamed up with Reloader 22
