.257/.300 Win Mag

Recommended Posts

Anyone hear of someone doing this kind of wildcat round for a little higher velocity Quarter Round?

I have never heard of this particular cartridge, but it would not equal the .257 Weatherby, a factory round available in a variety of rifles. If you want a faster quarter-bore, there is always the .257 STW, but it's a wildcat, as well...

HOC,

I probably have about 350 rounds down the tube. I do not have a bore scope to look at the throat. Have seen no loss of accuracy yet, but 350 rounds is not many.

 

If the BR guys get 1000+ from a 6.5-284, I should get 2000 with a reduced rate of fire and not getting the barrel toasty-hot, ya think.

I am very intriqued with the 6.5 Lapua.

 

257 - Look at the forums at longrangehunter.com on the round.

 

Saw a rifle that Accuracy International (tactical) built and it was shooting in the ones and twos.

 

I want to put together a rifle for sniper challenge matches and am leaning toward this round pretty hard, just dont know if the 6.5 WSMer wouldn't be better if the barrel held up.

 

I don't know about 2000 rounds, keep me informed. I have two 6.5x284's but less than 500 rounds through either. No reference there.

 

I think hot loading hurts too. Look at what happened to the .264 mag as a sporting round...Dont think that was from rapid firing.

 

 

Thanks Doug

H-o-C, I saw that AI rifle on the military channel yesterday. It was an impressive display. It sounds like it would work great on deer and lopes.

I've always wanted to do a 6.5stw or 270stw ar maybe a 270RUM. Then I dont wanna mess with the whole wildcat deal either. I never understood why winchester made their quarterbore a supershort instead of a regular WSM. Im even one of a few that likes the wssm cartridge. 264's are one heck of a cartridge. I know a guy on here that has one.

There were a lot of people left scratching their heads in befuddlement over the lack of a 25 WSM from Winchester.
