How close would these two be?

Read an article on the '6mm Creedmoor' which made me wonder if that round was being commercialized.

I recall JB mentioning the 6.5 parent round can be made from 22/250 brass, so figured the 250AI would be perhaps identical ballistically and perhaps almost the same in specs as a 25/6.5 Creedmoor.

Anyone?

I think there would be some following of 6mm, 22, and 25 versions of the Creedmoor and based on past success of calibers in this country, would expect the first two might be more popular. A 22 version would be similar to a 22/250 AI, as a 6mm close to a say XC. A 25 Creed would eliminate brass forming for a 250 AI if mfg.

IF they ever are produced, I hope to see a fast twist 8" bbl used in the 22 and 6mm for heavies and of course a std. 10" ROT in the quarter bore.

I just wonder how 'niched' the Creed may be to competition shooters and if a larger opportunity exist with other small bore sizes - 22 thru 25. No doubt a 5mm version would be smoking hot!

The big difference between the Creedmoor and .250 AI (aside from the bullet diameter, of course) is that the Creedmoor has a 30-degree shoulder angle, and the Ackley Improved use a 40-degree shoulder.

In reality the 6.5 Creedmoor is more like the .250 RCBS Improved, which used a 28-degree shoulder. Which is why I didn't refer to the Creedmoor as an AI in my article, but a "6.5/.250 Savage Improved."

I am sure rifle loonies everywhere are necking the 6.5 CM up and down in search of the perfect cartridge. Whether Hornady will do so is debatable.

Thanks JB, a 30 degree seems better regarding feeding. On that note, any issues w/250AIs feeding well w/standard OEM magazine parts?

As us Loonies know, there is no round that is UTOPIA.

I see alot of potential in a 22, 6mm and 25 cal round i.e. on the 6.5C case, the benefit being having as low a recoiling round that shoots flat w/ample power for varmints thru deer.

No doubt, the current 22s, 6mm's, and 25s ballistically do those jobs now, though I appreciate the efficient design of the Creed case, low taper, sharper shouldered, and I like short actions.

To carry it further, no pun - a fast twisted 22 and 6mm might offer a niche not presently occupied to my knowledge in a mid sized capacity round. LR shooters would take note I believe.

I never could get the 250AI to feed consistantly in my 77RSI, so I rebarreled it to 25 Souper, which has the same case capacity and feeds better, at least for me.

Whats wrong with a 308?


The older I get the more I realize that you can pretty much kill everything with a 308. I've thinned the herd to the 308 Montana, and about 3 dozen flyrods wink

There is NO FLYROD UTOPIA!!!! But a high end RL Winston 4 piece 5 wt is CLOSE...

Dan, I guess where a 308 interest me is in using a 130 TTSX, which runs neck and neck with a 130 in a 260 (trajectory etc.) out to 400 yds.

Now don't even get me 'learned' in the art of casting a fly rod else I wish I might have taken to Golf wink LOL.

Good info guys thanks.

Oh, as to that one round dilema, LONG before I had my first rifle, I longed for a 270 b/c JOC loved it, so he wrote. I was sold on it - and owned a few......maybe someday I will go back to it as a mainstay, and who knows, I MIGHT just try a 308 one day!

For now, I prefer smaller bores for most of what I do, but you being in the big mountains where big critters abound, there may be some added comfort carrying a rifle of larger bore size.

I cannot argue that you have not chosen well.

Dan,

Back when I wrote perhaps a little more about flyfishing than about hunting & shooting, I had a pile of flyrods and only 3 centerfire rifles (.223, .30-06 and .338 WM). Now that I don't have time to write about flyfishing anymore, I have half a dozen flyrods and 50 centerfires!

So I guess it depends on how you define "need"....
