6.250

Hi. Just a few Q's. I read on this site & in the varmint section about a caliber called the 6.250

I have a new 22.250 & when it needs a barrel I thought of this cal.

My q's would be since the dies are harder to find & much more expensive, what is the real advantage?

I know a bigger, heavier bullet has advantages & some increased yardage but other than that?

Thanks

Also consider the original 250 Savage which is of course the parent case for 22-250. Redding do their series B dies for the 250 Savage, and series B dies are only a little more expensive than series A dies. Winchester still makes 250 Savage brass, and other companies may also but I haven't checked yet. That they are still making brass after all this time suggests that they aren't going to stop tomorrow. With the exception of limited choice of .257" bullets, the 250 Savage has a good story for varminting. The 75gr VMax may be all you need.

As I see it, one of the primary reasons for necking up the 22-250 is to get better barrel life, on which score the 22-250 is quite bad. The 250 Savage will be better again in this regard than the 6mm/22-250 .

Thanks for the info. I did look up the 250. Brass is priced higher than the 22.250 & not very available. Runs about the same as mags in costs.

I do like the ballistics on this & will keep this in mind when I need to re-barrel. I keep getting so many different views on the 22.250 & barrel life, guess I'll find out soon enough?

Very accurate * low recoil, which is an issue for me.

If I go w/ the 250 Savage, what twist do you reocmmend?

Thanks again

One decided negative against .257" diameter bullets - the selection of quality ones in 6mm and 6.5mm is usually better.
 
My wife shot a 6/250 for about 4 years. It was a very effective varmint round, and outperformed my 22/250 quite dramatically. She sold it to make way for a 204, but now that my 22/250 is into it's last season, I'm planning on rebarrelling it to the 6/250.

Redding makes dies for it, and they are easy to obtain.
 
250 brass seems to be cheaper than 22-250 brass:
http://www.winchester.com/products/catalog/components/rifleshellcases.aspx

The Redding dies for 6mm/22-250 are not cheap at $172.50 for a 3-die set because it is their D series. 250 Savage dies are in their B series at $118.50 . The B series dies are reckoned to be more in demand than D series.

Do not worry: necking up 22-250 cases to .257" is very easy, and you will have more choice. Also, try Federal brass in 22-250...

I will have to get with you on this, can you tell me who makes the equipment to neck up to .257 Is it the same as the 6.250, Redding?

Where do you get Federal brass? Not Midway.

Still lots of time, my 22.250 is new. Should have a few thousand rounds through it before I have to figure out which cal to step up to, the 6mm OR .257. At least I hope so, if I hold down the hotter loads w/my 22.250. 3400-3500 fps?

I have looked at both 6mm & .257. There is more selection on the 6mm but I will use 75-80gr for varmint not the 55's. I live in a windy area, a little heavier bullet is better here.

Which of these two cals has the best density/construction, in your opinion, gives the best performance, "is the best fliers", & barrel life?

As you know I am knew to this and to this web site. I very much appreciate all of your time & feedback.

Thanks again

The 6mm 75gr VMax has a BC of 0.33 .
The .257 75gr VMax has a BC of 0.29 .
The other considerations are pluses for the .257 .
The barrel life with .257 will be better again than with 6mm.
The .257 will push the 75gr faster than the 6mm, having more base area to push against.
I don't expect there are any differences in construction between .257 and 6mm 75gr VMaxes, at least none that varmints will care about. The .257 may blow up faster, having a larger impact area.

Thanks ghermitage, will look at this seriously

There is a particular risk with .257 that 6mm does not have.
If your .257 gun just doesn't like 75gr VMax no matter what quantity of what powder, suitable lighter bullets don't seem to be available. In 6mm you could go to the 65gr VMax or 58gr VMax, but in .257 these options don't exist.

I'm just not making fun of anyone, but it seems quite obvious to me that any 250 Sav die by Lee or Pacific or Redding, provided they're fitted with an elliptical expander, should resize a 22-250 case in to a 250 Sav...

Fed brass should be available at Graf's, Widener's, Sinclair's, or Huntington's.

.257" bullets are available from Sierra and Speer also, not to mention Berger or Fowler...

What I would do would be to wildcat the 250 Savage, asking a gunsmith to chamber a .264 barrel in 250 Savage using a removable pilot reamer, then to ream a bigger neck and a throat for .264 bullets.
I would use regular bushing dies in 250 Sav by Redding with a different bushing, et voila!! The whole range of .264 bullets would be available and barrel life would be longer.

Think about it...

Take Care.

Thanks, I thought the std dies would work, just wasn't sure. As far as the 6.5mm, I thought they would be a strech in size/weight for the 250 case capacity to really be an effective cartridge.

I have been told that velocity over 3000+ is what starts eating up throats/barrels.

Thanks for the feedback

The discussion was about varmint bullets, and the point raised was about the availability of bullets lighter than 75gr should they be needed in a particular gun for accuracy. None of the manufacturers listed there does a varmint .257 bullet of less than 75gr, and none does a varmint .264 bullet of less than 85gr. With 6mm, there are options below 75gr.

Note: the online listing of Fowler bullets that google found first is out of date - 2002.
 
Well one other option is to stay with the 22.250 just go with a faster twist barrel so I could use the heavier bullets like the 60-75gr's, right? Keep the velocity down to 3400-3500 fps?

LCS
 
With a 24" barrel and a 70gr bullet,
22-250 will do 3000 fps
6mm/22-250 will do 3225 fps

Also, with a 70gr bullet the 6mm/22-250 can be expected to have a good deal better barrel life than 22-250.
Recoil is the same, bullet weight being the same,neglecting the velocity increase).
In all regards but BC which only comes into play at longer distances, the advantage is distinctly with the 6mm/22-250.

I have found that using the cheaper 22/250 bushing dies and using 6mm bushings in them work quite well in making 6/250 ammo,also works for the ackley version. Reamer rentals are not that much from http://www.reamerrentals.com/and having your gunsmith use the reamer on your seating die when they chamber the barrel almost guarantees a perfect fit. RANDY

Can this be done w/o the bushing typre dies? Can I modify Redding seater die the same way?

Out of a 26" barrel, I shot the 70's at 3550 fps into tiny groups and never full length sized the brass using H-335 and cci200 primers, I believe the loads was 35.5g.

Was this a 22.250, what was the rifle twist, 1-12 or 1-14?

The 70's was bullet grain?

Thanks
