Starting a list for a new build for next year, calibre is 30 Boo Boo,( have RWS brass) action will likely be a BAT M, barrel 30" throat for 210 Berger vld, heavy profile, Jewell trigger, the stock is the sticking point, it will be for shooting supported either bipod or bag long range deer, thinking about a MacHale the rifle will be single shot, any pro's or con's on components listed, any words of wisdom, help would be appreciated.

What is a 30 boo boo?
I think Paul janzso might have started that one. I think it was meant to be something else but the reamer was stuffed up so it was called the boo boo.
As a suggestion if your looking at putting a long heavy barrel on a heavy action like that have a look at a thumb hole stock. I've got a couple of bat m's as f class guns. One used to have a thumb hole and was much easier to maneuver when shooting off a improvised rest.

As far as I know, Dave Tooley developed the BooBoos some time ago. A friend shot one with 190 and 210 VLDs at Butner some years ago. He is a big guy but he had to use a pillow in addition to a recoil pad when he shot the BooBoo in an F-Class gun. It is about like a 300 WinMag capacity wise. The brass life is what impressed me the most. He got 200 cases from Dave Tooley when he first got the rifle in what I think he said was 1994 and he still was shooting 190 of them when I met him in 2009 and that was shooting a lot with hot loads. A bipod and a muzzle brake would make a big difference with that much recoil. I shot a 7mm BooBoo on a BAT M with 180 Hybrids at about 3100 fps without a muzzle brake and it was just manageable but extremely accurate. I wouldn't want to shoot the 30 without a brake.

Anyone got a reamer print for a boo boo?
Forgot to mention, the rifle will be moderated, probably with an Ase Utra SL7.

Good point, thanks.
I've got RWS brass and you can treble that price you paid in UK poundsdkhunt14 said:

Anyone have a picture of the 8x68s compared to the boo boo?
GSPV said:
Extra case capacity and velocity, high quality and extremely strong brass that will last forever after fire forming, 50 firings on a case is not unheard of even when it is run hard.
Not a direct comparsion with the 8x68s but the cases are as follows:
223R, 7 SAUM, 300 WSM and 30 booboo.

The 8x68mm S rebated rim bottlenecked centerfire rifle cartridge (the S means it is intended for 8.2 mm (.323 in) groove diameter bullets) and its necked down sister cartridge the 6.5x68mm (no S, or anything else, required) were developed in the 1930s by Mr. Schüler of the August Schüler Waffenfabrik, Suhl, Germany as magnum hunting cartridges that would just fit and function in standard sized Mauser 98 bolt action rifles. This is one of the early examples where a de novo rifle cartridge (the 8x68mm S and 6.5x68mm have no other cartridge as parent case) was developed by a gunsmith to fit a specific popular and widespread type of rifle.

History[edit]
The German ammunition manufacturer RWS[2] (Rheinisch-Westfälischen Sprengstoff factories) introduced both cartridges commercially in the spring of 1939. With the official certification of the .375 Hölderlin and the 8.5x68mm Fanzoj this German 68 mm "family" of magnum rifle cartridges that all share the same basic cartridge case got expanded in the 21st century.
The cartridges in this German 68 mm cartridge "family" are, in the order of development:
8x68mm S (1939)
6.5x68mm (1939)
.375 Hölderlin (2007)
8.5x68mm Fanzoj (2012)
The M 98 bolt actions and magazine boxes of standard military Mauser 98 rifles have to be adapted by a competent gunsmith to function properly with these magnum cartridges since their cases are longer and have a larger diameter than the 8x57mm service cartridges. In properly adapted standard military Gewehr 98 or Karabiner 98k service rifles the large 8x68mm S cartridges are however praised for very smooth and reliable feeding.
The widespread availability of standard size Mauser 98 rifles and the fact that the .375 H&H Magnum cartridge and its necked down version the .300 H&H Magnum with approximately 72.4 mm case length were too long to fit in standard sized Mauser 98 bolt action rifles makes the shorter 8x68mm S, 6.5x68mm and .375 Hölderlin interesting chambering options.
World War II spoiled the commercial introduction and spread of the 8x68mm S amongst German hunters. The cartridge became due to its high performance and flat trajectory popular after World War II when German hunters were allowed again to own and hunt with full bore rifles. The 8x68mm S performance also made that hunters who had problems with handling magnum cartridge recoil stepped down to less powerful but for German conditions adequate medium cartridges like the 8x57mm IS, 7x64mm (Brenneke) or .30-06 Springfield (also known as the 7.62x63mm in metric countries). Recoil sensitive shooters can fit an efficient muzzle brake to significantly reduce the amount of recoil. With the help of a muzzle brake the 8x68mm S recoil is reduced to tolerable levels.

Extremely thick brass results in 'only' 5.58 ml (86 grains) H2O cartridge case capacity for the 8x68mm S. A rare feature of this

Yes the case taper is reduced quite a bit, the original diameter at the shoulder is .478 and the Booboo is slightly above .500, and using a 40° deg shoulder instead of the 17° that is on the original 8x68 case design.
Case capacity is 90 grains + somewhere, it will also depend on what brass manufacturer you choose RWS, Norma or Horneber.
The European 30 Kovacs is altered even more for extra case capacity, and the other wildcat designs have varying degree of case taper reduction, and 30,35,37 or 40 degree shoulders so there is a bit of difference in capacity in all the similar designs.
If your really interested the Booboo is proprietary to Dave Tooley, and if you inquire he will gladly give you some solid information on it.
I do not own one yet, is the first thing on the list when the Shehane is finished at the start of next year. So i have only done some basic research on the design
