243 WSSM and 25 WSSM AR Upper Questions

[j_smith01]

hey guys. I have an AR lower that needs an upper. I found an Olympic upper in 243 and 25 WSSM that sounds kind of interesting. Looking for opinions on these cartridges, would one be better than the other, and also this upper, have heard some bad reviews on Olympic stuff, hows this one......anybody know? Also considered the 6.5 Grendel........experiences and opinions on this one would be great too. Uses will be target shooting and some deer hunting.

Thanks

The WSSM calibers are basically short WSMs. They are good, but they burn barrels, the .243 is equiv to the 6mm remington, and the .25 to the .25-06. They will burn barrels just as fast with light bullets.

The 6.5 Grendel is a great cartridge, with good brass available* and a wide selection of bullets. THh problem is, parts and brass are kinda hard to find (this is the "*"). AA has restrictions on it, and they are not letting people make 6.5g rifles and ammo without paying royalties, which most companies are not willing to do.

What kind of barrel life can be expected from the WSSMs?

If you want an interesting upper take a look at the 300 Whisper.

You can load heavy, slow and very accurate long distance 240 grain rounds or you can load to just under 308 performance with 150 grain rounds.

And you use very little powder in the process.

.243 WSSM – The Long-Awaited 6mm "Answer"?

Introduction
Despite their wide-spread use as sniper cartridges, the .223 Remington, .308 Winchester, and .300 magnums are arguably less than ideal. Each has inherent limitations which reduces its effectiveness, and many in the sniping community have long awaited a better "answer". One possible "answer" that has repeatedly resurfaced during this search has been the prospect of a high-velocity 6mm cartridge. In the past few years Winchester and Remington have offered several new short magnum cartridges, one of which may be that "answer". This article compares the .243 WSSM's ballistic performance to current service cartridges, discusses the range of .243 WSSM options available to the tactical marksman, and speculates on options that may be available in the near term.
