I went to the Whittington Center today with the 6mm Beggs .269 neck and played with 4 bullets. My barrel didn't like the Rubright 68's or the Zia 68's:(
but the 58gr Zia's over 25.0gr H4198 shot in the low 2's. Gene says that load with a 68gr bullet hits about 3400 fps. With the 58's, Who knows. I did not bring my clock, but they have to be over 3500.
The last bullet tried was Randy Robinette's 67.7gr bullet. Over 24.6gr H4198 and a Winchester primer I got a .140 and a .195 before the wind picked up and knocked the flags over.
The tuner works as advertised.
I'm a happy camper!

Hey there Bryan,

How has NE New Mexico been..? Hope some snow or heck, just some needed moisture has been around there this winter. 2006 and early 2007 were pretty dry !

How has your Hornady die been?

Sounds like a good shoot'n session. Learned some things.

Take care and see ya Memorial weekend,
cale

The die is perfect. I've had some trouble in the past with bending the pins on Hornady dies, so I have some extras. It was a good day. I learned some things, and have a lot more to learn, but the Beggs cartridge gives up nothing to the PPC. I need to clock that 58gr load! I'm certain it has the same speed as the .22's and a way better BC! I really think the round is ripe for lighter bullets.

Brian,

If around 24.6 is a good load with the 68's it would seem reasonable that 25.0 would be pretty mild with the 58's. Did you try a hotter load with the 58's, like 25.5 or 26.0 maybe ??

Just interested.

Bryan,

Something that doesn't seem to have been mentioned with the people now shooting the Beggs is the case growth, the big down side of a tapered case, or so it is said !!

I shot a two gun with 15 x 6PPC cases, plus practice etc so each case had 20 firings plus 5 before they were pressed into service. They started off trimmed at 1.495 inches and now measure 1.502 - 1.505 inches. After 25 firings they have grown no more than 10 thou and are still 20 thou short of the chamber end.

Just wonder how the Beggs stacks up with the altered radius and all ??

Good question, glad you asked. I make a "case maintenance" trimmer. It is designed to "skim" that little bit of brass that always results from multiple firings......makes a case grow. (or should I say Flow). You can't put 70K pressure on the inside of a soft metal case that is contained in a harder metal without some of it moving. I trim 6PPC cases every other target, and find that I am removing no more material with the Beggs than with the PPC. The system works.
As far as velocity is concerned, I can only say that the same load with 58gr bullets yealded signifigantly higher velocities than the 68gr bullets in the PPC and would expect to see similar results in the Beggs cartridge. I will clock them when I get the time.
Is there an advantage to shooting the 6 Beggs? Probably not, unless it allows the use of other powders than N133, which could very well be the case. Disadvantages? None that I can see.
Good Shootin'

6mm Beggs

I devoted two good weekends to the 6mm Beggs, I made up about 25 cases, and shot no less than 200 rounds through the barrel. I experienced no more case growth than I do with my 6PPC, probably about .005 to .008 per case through the entire testing.
With my Rail Gun,I would say that the 6 Beggs leaves nothing on the table as far a grouping capability goes. I shot some very small groups. You can hit 3400 fps with a 66 grn Ultra if you wish to go there, but velocities in the lower to mid 3300 range are the practical upper window for the sane world.
One thing I did mention is you have to be carefull in using a chambering reamer with as much body taper as the Beggs has. In other words, it cuts all the way. .001 advance yields a greater increase in diameter than with a reamer that most of us have become used to. Just be carefull. You can mess upa chamber in the final few passes. ( yes,Ilearned this the hard way,even a san experienced machinist).
As for the practical application of the Beggs Cartridges, I think the 22 is where the real advantage lies. For all purposes, with the 6mm, you still have to go through most of the same steps in case prep as with the 6PPC. You have to neck them up, turn the necks, and then fire them at least once. Most of us fire a 6PPC twice before we take it to the line, that might be the only step you save.
But the 22 is a different story. If it will shoot just as well as a 22PPC .100 short, and case life becomes a non issue, you then have a good option if you choose to shoot a 22. And of course, you don't have to do all of that case forming, which is the big Achilles Heal of the 22 PPC short.
In my opinion, the 22 Beggs is where Gene should concentrate and put his best efforts towards developing to it's fullest potential.........jackie
 
chamber reamer

Jackie, you mentioned issues using a reamer with this much taper and that you had to be careful.
"One thing I did mention is you have to be carefull in using a chambering reamer with as much body taper as the Beggs has. In other words, it cuts all the way."

What can go wrong that you have to be aware of and guard against? And how do you go about keeping it from happening?

I too agree Jackie,

In the limited effort I have given, the 22 WILL shoot.

Seems to prefer n-133
 
With the 22 Beggs, a full case (halfway up the neck) of Vit133 (51.75 clicks) was giving me 3410 fps with Bart's 52gn bullets. Accuracy OK. No pressure.

50 clicks on the Harrel of Hodgdon Benchmark was giving 3580fps and better accuracy. Again, no pressure.

My barrel is only 20 inches as I rechambered a 22PPC short.

Any more data guys?

Good Feedback Guys

Experimentation continues almost daily in the tunnel with the 220/6mm Beggs cartridge. Hodgdon's Benchmark has emerged as the winner thus far in the 220. With Cheek's 52 grain flatbase bullets, muzzle velocities of 3500+ are the norm with exceptional accuracy.

Satisfied that the 220 Beggs is now as perfect as it can be, I have been concentrating on the 6mm. To say that I am very pleased would be an understatement. All of my 6mm barrels are now chambered in 6mm Beggs with a .269 neck.

Some have suggested that I should concentrate on only the 220 version of the cartridge feeling that the 6mm version cannot compete with the 6ppc. Nothing could be further from the truth! It gives up nothing to the 6ppc. Hodgdon's H4198 is THE powder for the 6mm Beggs. It does not heat the barrel like other powders and felt recoil is noticeably reduced from that of a 6ppc sporter shooting N133.

From my 22 inch sporter, Bart's HH6 68 grainers have a habit of following each other through the same hole with 26.5 grains of H4198. Average muzzle velocity is 3380 with very low extreme spreads. The cases go in and out of the rifle as smooth and effortless as can be and seem to last forever, growing maybe, .002 after a dozen firings. I have never had to trim the cases after the initial trim. That says a lot about the chambers and the custom Hornady sizing die.

The 220/6mm Beggs cartridges are part of a shooting system, each component designed to work perfectly with the others. The entire system consists of,

1. A two-piece, aluminum stock in which the forend bolts directly to the barrel and is adjustable fore and aft for proper balance.

2. Both the 22 and 6mm use the same Hornady sizing die.

3. An adjustable, 3 oz., tuner is standard equipment.

Hope to see you all at the Super Shoot.

Gene,

how perfect did the 22 perform, AND what is the magic Benchmark load?

Thanks,

Ed

Ed, accuracy with both the 220 and 6mm is limited only by the quality of the barrel and bullets. As far as the mechanics of the cartridge, i.e., sizing, loading, function in the rifle, etc., I believe they are as perfect as can be.

You asked, "How perfect did the 22 perform?"

Of course, no cartridge has ever fired the 'perfect' zero group. I don't measure every group I shoot, but I can tell by looking whether or not a rifle is performing at a competitive level.

You asked, "What is the 'magic' Benchmark load?"

All rifles are different and some will accept more powder than others, but 27 grains of Benchmark is producing about 3650 fps from my 26 inch HV barrel using a Stiller DropPort action. This is with Cheek's 52 grain flatbase bullets. Of course, it goes without saying; always start out a couple of grains below maximum and work up slowly. If you begin seeing signs of excessive pressure,, STOP!

Depending on the details, this could violate the "bedding" rule. As I read it, no part of the stock may touch the barrel four inches up from the boltface.

I'll refrain from saying what I think about that rule.

Charles, this question has come up before. While designing the 'no-stock' rifle, I studied the NBRSA rule book carefully and could find nothing that prohibits the use of this type of forend. Bedding? The rifle has no bedding.

The 'no stock' rifle was introduced last year at the Cactus and was inspected by both Dennis Thornbury and Don Neilson. Both pronounced it legal.

Photo?

Gene,

How about a photo of that "no stock" rifle?

Thanks,
