.200 short 22BR

I shot a .200" short .22 BR for several years and really like the cartridge. There was a lot written about it in Precision Shooting in the mid-to-late 90's. I switched to a .100" Short .22 PPC around 2001 mostly because Dwight didn't want to open up a bolt face. In my opinion (which you are stuck with... I shot it a lot more than anyone I know of) it is a accurate as a 6PPC or any other real good BR cartridge.

I have a ton of information on this cartridge. Call me or email me if you want more. My phone number is in the columnists page in Precision Shooting.

Skeetiee,

The "theory" seems to be when the neck angle and length of neck is long the focus of the hottest gas is inside the neck rather than more downstream and into the bore.

Dick,

The .200 short BR sounds like it would be fun. How much powder were you using in the case? What was your barrel life like? Do you have a drawing of the reamer?

Years ago there was an article in PS about long necks and barrel life. The author wrote about what Jon has explanine and had line drawings supporting his thesis. I have no idea what year it was but perhaps there is an index somewhere.
 
Pete, that's the T.P. (Turbulence Point) theory. I believe Bob Greenleaf was the author of those articles.

Good shootin'. -Al
 
No Al, it don't believe it was Bob Greenleaf -- he has more sense. IIRC, the "Turbulence Point" theory was completely disproven. All they did was to assume the PPC was perfectly proportioned, and evaluate other cases by those numbers.
 
Thanks for the clarification on the author, Charles. Now I'm gonna' have to drag out my old PS Mags and make like Henry Jones (Jr.). ;)

As for the theory....:eek: -Al
 
I have not seen the Turbulence Point theory disproven or proven. I am 71 years old. I was shooting M-1 rifles at 14. Over the 57 years I have fired more rounds than most, made many observations and I have always made notes. My experience suggest that when the T.I. is inside the neck the barrel life is usually longer. But not always. I think this is because there are many things in addition to the location of the T.I. that come into play.

Rather than high jacking this thread I will start a new thread. "Barrel Life" for this discussion.

Check it out.

Thanks for your interest.

Our hope is these new Waldog barrels with the longer necks will last longer. ...

How much longer did you make your necks? I've shot a .22 PPC .100 short that leaves the neck full length. I shot it in a rail gun a year or two and in a few varmint class rifles. It shot well and was less work than making standard .100 short's. The main disadvantage to shooting a .22 is mirage at 200 yards. I've shot groups at Midland before where you shoot your group with a .22 and find out where you hit on the target when they hang the target on the wailing wall.
 
Mike,

Our reamer (Pacific Tool) uses a 0.246 OD for the neck. Neck dimension on the reamer is 0.314.

Usually I shoot the moly coated bullets which leave a better ring on the target. Makes spotting the hole better. (Still an issue at longer ranges with a 36D scope.)

Mostly we shoot at 100 yards due to range limitation. At 200 yards I would expect the 100 short to be better than the Waldog a 125 short.

since you have played with a 22ppc .100 short in a rail gun, can you conclude that a 22ppc .100 short is as accurate as a standard 6ppc? With the one barrel i have on my bag gun, some days the 22 short is as accurate and some days it is not. that has been my limited conclusion. you sir? Lee
 
I've won more matches shooting a .22 PPC .100 short than with a 6 PPC. The only time I've seen a disadvantage to the .22 is when you can't make out your bullets because of the mirage. The main reason I don't shoot a .100 short more is that it's easier to make brass for a 6 PPC. I have ordered a couple of .22 barrels for next year along with 6's.
