As far as I know the 30 Aardvark is a 30-30Improved, I believe I saw somewhere it was used in "Hunter Bench rest".

This should cover the 6x44

World Record 6x44--the "6BR Long"

Here's and old thread on 6mm-250:

6mm-250 ??

I am planning on building a varm/pred rifle. I already decided on the basic Savage m10 platform, from my question I asked earlier. I was just wondering about the 6mm-250 chambering, I don't see a lot of people using this wildcat much. I was planning to go with the 6mm BR and a heavy sporter...

Thanks Brians

I'm building a 6x250 now on an old XTC gun. Hobbled together a sizing die and have a seating die on the way. Mine is an 8 twist and I expect around 35-37gr H4350 to be about right with 105 class bullets. 22-250 or 250 savage brass work. Depending on chamber specs, 6 creedmoor brass may work and get you small primer pocket.

 

[david12601]

Sounds interesting 6-250 seems like it could be a fun gun

 

[Pawnee Bill]

If these are vintage rifles, the 6x47 is a 222 Mag necked up to 6mm. It was the BR master for a while, until the PPCs came out.

 

[snert]

Every one of those smiths are or were gooood at the craft. Seely Masker guns are held in high regard. A Ferris chambered PPC? Methinks I would keep that just to shoot now and then.

You got a lot of history there my friend.

The 6x250 will come scary close to the 6 Creedmoor. I think .011 shy actually.

6.5x47L, 6x250, 6 creedmoor, 6xc.

 

[david12601]

The .30/30 based 30 Aarvark is among the very efficient thirty caliber cartridges, and proved it's worth in Hunter Class bench-rest competition. Those who were able, used the Federal made 30American case, which featured small primer-pockets. I have attempted to attach a print (rimless version), sent to me, by Gary Long, in 1997.

Also, if it works, a pic of L-R: 30x47HBR; 30Aardvark; 30 IHMSA - all of similar capacity, & very good cartridges. Keep 'em ON the X! RG

P.S. I believe that Frank McKee (one of the BEST Hunter Class competitors to walk on earth) told me that his original gunsmith, Dale Madera (Sp?), head-spaced on both rim and shoulder. The large primer brass worked very well. During the mid 80' through the 90s', replete with experimentation - "those were the days"! BTW, Frank performed the majority of his posterior bruising using a pair of Rem. 788 actioned rifles, "trued"& bedded by Mr. Madera, and barreled/re-barreled by both Dale and Gar Long.

The 6X47 Remington is a .222 Magnum case necked up to 6MM. The 6-250 I think that was also called the 6MM International.

The 6mm International was/is a somewhat shortened [body] version of the 6/250, featuring a longer neck.
While both share the same OAL (1.912") the International sports about, 0.119" shorter body: 1.531" bolt-face to neck:shoulder junction, while the 6/250 is about 1.650". The International features a .381" neck, to the 6/250 length of 0.262". Both are excellent cartridges. These dimensions come from SPEER #9 hand-loading manual: page 146 & 147, 6mm INTERNATIONAL. I'll attempt to include a pic . . . RG

I believe that was the Walker version of 6mm International. There were a couple out there. But, all the versions were different than 6x250.

This is correct - this is the version used by Remington, for the 40XB rifles - the other versions of the 6mm Int. varied the distance to the shoulder and shoulder angle. All are very efficient and capable of extreme precision.

To add more depth, and hopefully, not muddy the water, here is a pic, of the 6x47mm (.222Mag necked up to 6mm), from the same SPEER manual, covered in pages 143-145, . This one, I never messed with . . . note that Mr. Walker dictated a 1:12" twist - a most excellent twist for bullets up to about 0.90" long! Jim Steckel(Sp?) may have had finger prints on these - they are, certainly, all over the BR family - my memory can be faulty. RG
