new hunting cartridge,6.8 x 260) ?

[Austin]

Thought of this today.A 270 version of a 308,243,260,257 class.
I don't know about it,maby there is one.It may be a good deer round.A mediocre round with a little more punch than a 243,257 or 260.Bullets could be 6.8spc 115grainers,130gr cor-lokt, 130gr speerGRANDSLAM,110&130gr barnesTRIPLE X,or other bullets in 90-140grs.Tell me what you guys think.

Brass is easy also.Neck up from 243,257,260 and down from 308.

I gather it has been tried quite a few times in the past. It never took off as a hunting round because comparison with 270W was hard to escape, and those wanting to use a short action had the 7mm-08. It would be a fine round, but pressed to make a name for itself in the company of some established cartridges.

JMHO butI see no practical purpose for this round or a 270 win for that matter. Go with a 7-08 and actually have an assortment of bullets to choose from and better performance.

If it weren't for the crapload of press from Jack O'Connor the 270 Winchester would have passed into oblivion,or at least be on life support) long ago.

7mm-08 has better performance than 270W ?
The difference in accuracy due to case design isn't going to show for hunting. If you are figuring an efficiency argument, that leads to 308W.

Actually the two cartridges I was comparing wer the 7-08 and the 270-08, since this is the cartridge in question. My point about the 270 win is that it has a very limited bullet selection and will be outdone by a 280 Rem if you wish to compare apples to apples.

 

[ghermitage]

Why stop at 7mm? There is a truly great selection of bullets at 30 cal, more bullet base area, more efficiency and better barrel life. One could choose 308W or 30-06, depending on one's taste in fruit.

Is there something special about 7mm, such as a particular relationship between cross-sectional bore area, bullet weight and ballistic coefficient ?

I have always argued for 7mm, but this time I will play the other side of the argument to see with what logic others are running.

Thanks all.
