Home Forums Reloading Varmint Rifles 6mm22-250, does anyone use one?

I am considering the 6mm22-250 cartridge instead of my 6mmNormaBR. I want something with similar power and low recoil. Also I want something that will feed from a magazine. I have tried to make the 6BR a repeater, but I gave up and made it a single shot.

try the 257-22-250???

I have had two 6/250's, customs for shooting chucks and P. dogs.

60's at 3900, 70's at 3550 were very accurate and the only powder I ever used was WC844 which is H335.

If you are considering going this route, then you may consider the 6/250 AI, which will get you another 200+ fps at a minimum, and is a very accurate cartridge, I shot the barrel out of two of these also.

Both of these cartridges will feed from the magazine fine.
The 6/250 AI is right on the heels of the 243AI with less powder.

With either cartridge, you will be happy, make no mistake about that fact, however you will not have quite the accuracy of the 6 BR.

Your choice of the 6/250 over the 6 BR is a good one due to the cost of brass...exactly my thinking as my 6br's were finicky to feed out of the magazine plus the fact that the brass was lost while in the field shooting coyotes.

Pac Nor Super match barrels are what I used on these 4 barrels. I sent them dummy rounds with the bullet seated the way I wanted it and they matched it perfectly with no extra charge. I used - twists on both cartridges.

Good Luck

257-22-250, that's a new one for me. Do you have one?

Keith,

Thanks for the reply. I am interested in the standard version and I was hoping for 70's between 3200 and 3400 fps. I want a mild 6mm which is accurate and can feed from the magazine. Now that Lapua is making 22-250 brass I was hoping to just neck it up and go. What twist did you decide on with your barrels?

I have two of them, set up differently......28" heavy straight K&P, and a 25"Schneider Rem Varmint contour. Both are 12" twist, braked. One uses PMC 22-250 brass necked up, the other uses WW .250 Savage necked down. The idea was a 6mm with performance not too far behind a .243 but using enough less powder to cut way down on heat and fouling. It does that fairly well. The 70TNT with W760 is a good combination. In my guns the best is WC844 with a 65 - either VMax or one of Keith's nasty 65gr HP's - at about 3690. But after having these since the mid-90's, if starting from scratch I'd do as Keith said and just make it a 6-250AI. If choosing between 6BR and 6-250, I'd stay with the 6BR which pushes light bullets only slightly less fast, is stupid easy to make shoot, and uses a whole bunch less powder.

Ackman,

How much less accurate would you say the 6mm22-250 to be or is it just a little harder to find the right load?

How about 6mm Creedmoor? Hornady is making properly head stamped brass available through G.A.Precision. He also has dies available.
G.A. Precision is building AR-10 style rifle in this caliber, so it should feed fine from a magazine.

Here's more info on the brass

CamW,

How does it compare in terms of water capacity?

I have a 6-250 that I absolutely love and I'd highly recommend it to anyone who reloads.

Mine gives me fantastic accuracy using:

Sierra 60 gr HPs & IMR-4895 @ approx 3700 fps
Horn 75 gr HPs & RL15 @ approx 3250
Sierra 85 gr HPBT & Ramshot Hunter @ 3300 fps
90 gr NBT & RL15 @ 3k
90 gr Speer Hot Cor & Ramshot Hunter @ 3250

Crazy thing about my rifle is it puts all those (sub-MOA) loads into nearly identical POI so it is the ultimate multi-purpose game rifle.

efw,

I sure don't want to sound like some of those guys who don't understand the .22-204 and say it's just another .222 Rem Mag, or somehow can't measure up to the .223AI., etc.

That being said, what does the 6-250 offer that a .243 or 6mm Rem won't do? I'm sure you have your thinking on why it needs to exist and what it offers.

So, please educate me.

I don't know.....MY own 6BR is extremely accurate but that doesn't say how yours is. That gun is more accurate than MY 6-250's but I can't say how much more, or how yours would be if you had one. It was easier finding best accuracy with the 6BR because that cartridge is just stupid easy to work with.

Seriously... I just stumbled into a deal on a rifle that I liked and I've always had a thing against the .243 Win (270 also... and I freely admit my "thing" is not connected to any rational line of thinking, just "because") so it appealed to me.

The fact that it shot lights out only confirmed my initial attraction. Add to that the facts that it has less case capacity than the Win but, from my limited experience, it does extraordinarily well velocity-wise while maintaining a rather substantially decreased amount of blast & heat, and you've got a winner.

I guess that is the long way of saying I got no answer for ya. I certainly wouldn't advocate it being offered as a commercial cartridge, but for the use the OP appears to be seeking, particularly if he is into these rather obscure cartridges (like the BR), it would make sense.

When my throat gets toasted I'll likely have another rifle built for this cartridge and make great use of my 26" long sako tube by rechambering to 6-06!

Dirtfarmer this is for you......

Thanks for that info.

How does the 6-250 stack up against the 6BR/6PPC bench rest rounds?

DF

Thanks for the information on 6-250s, it's been on my list for some time, as I think the 22.250 is too snorty while my 22 BR is just about right for "full power" 22 cal. But feeding stinks.
So, I'm gonna go for the 6 Imp, there are three versions and I want the fattest shoulder.

Would you need a custom reamer, or could you just have a 'smith cut a 22-250 AI chamber and finish w/ a 6mm neck reamer?

efw,

How did the Speer 90 grain perform on game?

I haven't had a chance to kill a deer w/ 'em yet... hoping to do that this summer on some crop damage permits!!

I would be interested to see how they do. I have an uncle and cousin with Remington 722's in 244 Remington. They usually use varmint weight bullets and I always wondered how the Speer would perform.
