Hello,

Anyone using the 6mm/22-250 cartridge?

Stumbled across an article on it in the October 2001 issue of Precision Shooting magazine. Gunsmith Fred Szablewski (Sabreco, Inc.) says it's a great choice for 600yd matches.
His 1/8 twist pushes a 107gr bullet at about 3025 fps.

Looks like a good candidate for long range coyote sniping.

sounds great, i think

3000 fps from a 107gr bullet. making brass would be easy too. ballistically one would have a cartridge called the 243 win. come to think of it, i think david tubb used something like that ( i believe he called it the 6XCH)till everyone went to the 6X47 lapua recently. what the heck if i had a pile of 22-250 brass sitting around that is what i would do too.

Hello,

The 6mm/22-250 appears to be more efficient with less powder for the same bullet.

I think the 6x47L is a great cartridge but it's only one step up from the old .243win and barrel life is always a consideration.
Correct me if my conclusion is wrong.

Thanks, Larry

Your conclusion is wrong.

:D

The 6X47L is a better cartridge choice than the 6-250.

6 hls

Anyone played with the 6HLS?

Several versions, but basically a 6 mm Rem reamer run in to the length of a 22-250. There was a PS article on it several years ago.

Merry Christmas,

6mm22-250

AZLarry: I also read the article in P.S. in 2001 about the 6mm22-250. Was looking for an alternative to the "barrel-burning" 243. Had a chambering reamer cut, Shilen Varmint contour stainless 1-10, Redding bushing die, micro-seater, etc. Had a lot of $$$ invested, worked with it for 6 yrs., nothing special. Others may have great success with it, mine was mediocre. 5 shot groups were slightly under moa. A good learning experience, but would not do it again: too many really great cartridges out there, like the 6BR and others. Just my experience/opinion. Probably created some "work" for 'smiths, before some other "wonderful" cartridge got its' 15 minutes of fame.
 
I cannot believe that this subject keeps coming up - over and over again.

In the 1990s, and even before that, there were so many 6mm mid-sized wildcat cartridges that it was impossible to count them all. In the 47mm, 48mm, and 49mm range there were dozens of them. Ballistically they wasn't a nickel's worth of difference between them. Making brass was a chore for some and relatively easy for others. But all of us yearned for the day when good factory brass would be available. Well that day has come. In 47mm length you have the 6x47 SM and the 6.5x47 LAPUA. In 49mm length you have the 6XC TUBB. Why would anyone want to go back in time and make a wildcat case??? :confused::cool::rolleyes:

Buy a supply of the brass you want to use, get a reamer to match from Dave Kiff, and start shooting. But if you are still determined to make your own wildcat, send me a PM and I'll send you a list of at least 10 that will meet your criteria. And I'll include photos. You'll have to make up your own name.

Good Luck

Ray

6XC and don't look back

I've had most of the mid-size 6mm wildcats and have abandoned them all for the 6XC. In general, that capacity of powder and a 6mm bore is a very happy proportion.

I have 6HLS and 6mm Remington International reamers to sell if you are interested. But I strongly suggest you go with the 6XC. Its so easy to buy reamers, brass and dies that all work together.
 
After reading this and other info I agree the 6XC is the best choice going.

Thanks all for your insight.
 
The availability of Lapua brass and its higher pressure tolerances and uniformity is reason enough for many folks to choose the 6x47.

Don't forget too that the Lapua case provides a small rifle primer, while the other cases have the large primer. If we can believe what Dr. Louis Palmasano and Ferris Pindell tell us, this should translate to improved accuracy and might be one more consideration when choosing between cartridges.
 
And if you choose NOT to believe the estimable Messr's P. and P. of PPC then just test it yourself. You can (I HAVE) test Lapua brass for Lapua brass amongst the various cases.

A small primer pocket case WILL WIN and does and historically HAS in every 22/6MM venue.

The 6X47L is the winning case.

G D Tubb had the 6XC case manufactured to his specs. We all followed it's development closely here on the board. I have samples of gen 1-2-3 brass, you can search the archives to find all sorts of information from back in the day.......back when neither the 6XC nor the 6X47 even existed. I was one of those who ordered 500pcs of the 6.5X47 brass months before it was available.

Here for instance is one post which I turned up, PRE-6X47, there are many.

http://www.benchrest.com/forums/showthread.php?t=29295&highlight=6X47+alinwa

Anyway......We begged for YEARS for this case. I tried to find out from Lapua just how many cases we'd have to order to get them to interrupt a run and give us UN-DRILLED flashholes. OR, ideally, a run of cases with small primer pockets. For 5 yrs, no dice. Then the 6.5X47L showed up on the radar.... YIPPEEEEE!!!!!!.....Lapua either listened or saw the light on their own, the 6X47L IS THE CASE that we who wanted it hoped it to be. It is the new standard for both 6X47 and 30X47 or HBR cases. My hope is that it will revive HBR as a sport.


My point is this, the 6X47L is measureably, quantifiably, the superior case.

there ya go

the verdict is in AZLarry you HAVE to snipe coyotes with a 6X47 Luppie. ;)
Just having some dry humor, :D dont have a cow!!?? :cool: Fred
 
Back near the end of the stone age, in the mid 1950's, several people around my area experimented with a 6 mm built on the old 250 Savage case and it worked very well. :)

This forum is fun. I went from asking about a wildcat in a magazine article to building a custom coyote rig in 6x47L.

Found details on twist, reamer specs, bullets and loads at www.6mmhot.com. My primary interest is with the 95 to 107gr bullets.

All of you have educated me well. If I'm going to step into the 6mm world might as well do it right.

Thank you and happy hunting, Larry
 
Another vote for the 6X47. I have them in 1-8, 1-12 and 1-14 twist. The quality of the Lapua brass rocks. I have become a Lapua snob - if I can't get Lapua brass, I won't fool with that chambering.

Out of the 1-12's I am running 3850FPSwith a 70 gr sierra blitzking with sub 1 inch 300 yard groups. Very happy for a non match bullet. No pressure signs at all. I know Alinwa gets greater velocity, but I am not quite sure of his sanity (sorry Al, love your posts)

Out of the 1-8's I am running 3200+ fps with 105 bergers with no pressure signs. Some 300 yard groups have 5 bullets touching - I have several .25 inch groups. I wish someone would make a true varmint bullet in 100+ grains. Don't use Bergers, Sierra or Hornday match bullets on PD's - they pencil hole at longer range. Not humane.

Just started working with the 1-14's - used a zero throat reamer - will try 55gr bullets and see how they do. 4000 FPS with a wider cross section than a 22-250 ought to make the fur fly.

I have my 4 & 5 PD trip with the 6x47 case scheduled in May, then July. Fur definately will fly.

Now have 3 different reamers for this case. I had been shooting 6mm remington's, 6MM Ai's , 6MMBR's, 243's, etc. The 6X47 is the 6MM answer. I rebarreled every other 6mm to 6 X47.

Andrew,

Don't neglect to try the 55gr NBT from a TIGHT TWIST barrel!

The extra rotational energy is AWEsome........ you touch meat with these bombs and it's like who flang a cat ag'inst the grain bin. Extreme auditory verification of hits. Everybody on the friggin' RANCH knows you hit something.

Now, this next is anecdotal....... take it with a large grain, nay a SNIFTER, of salt .... but I could line you up with three different folks who'll SWEAR that the ejecta leaving the spotter's scope is revolving in a CLOCKWISE direction! ;)

Now my wife just sez...." Well, THAT was gross"......


But anyway, just hit 'em center-mass,high, SUCK 'em out of their burrows......and you'll NEVER have to worry about them finding their way back to their liddle holes. Unless you're hunting miniature squirrely T-1000's with their mimetic-poly alloy construction and even THEN the particulate matter is divided wicked fine......

The only thing more extreme is the 300WSM spitting 112gr BIB's @4200fps......... but that's another story entire.....

:D

Al,
Have you whacked any critters with the 6 X 47 Lapua? Curious as to what kind of varmint rig the cartridge would make.

Never mind Al, I just read your thread (above). Might have to just get one of these to whack feisty PA groundhogs.
