Thanks George, that helps.The original design by Fred Hasecuster was an .080 short br. the photo looks a little shorter, but there where many variations by others that where also tagged talldog...
They look FUN!These days theyre good for a tinkerer but serve no purpose. Good brass is available now
Yes they used remington brand BR basic brass usually. Lapua brass is pretty bad in the old br rem designed chambers. We had a real bad shortage back in the late 90’s on ppc brass. The resourceful guys had reamers made to tune the powder capacity of the good br brass that was available like mr ulrich said above. Me, i was a hard head and used sako ppc usa brass until i was staking the primer pockets ruining boltfaces (like everybody did back then. You can slways spot an action from that era) and i was also using the shittiest brass available- bulk once fired 7.62x39. I still have that forming die set somewhere. Man that was awfulDusty most of them probably used Remington BR brass or norma, and the back end of those old chambers are small, and using Lapua brass caused problems unless you open them up ! Full length dies were Remington 6BR with the proper amount removed off the bottom of the die, They presented a lot of problems in case and die’s if you were trying to rekindle a old gun with today’s components ! Been there did that, But mine would shoot,still have all the stuff From the late nineties !
George, you likely nailed it.Most of these cartridges where made to match volume to burn rates of powders available at that time...Gerald Forys played a bunch with shortening the br to get the volume wanted..
I bought a 22 REM BR back when I didn't even know what they were. It was a 40X from the early eighties, Rem chamber, tight neck -- I went to the trouble of a small base die, neck turning -- would have been waaayyy ahead to just open things up a bit with a reamer. And of course when I got some non-Lapua brass, there was no problem.Dusty most of them probably used Remington BR brass or norma, and the back end of those old chambers are small, and using Lapua brass caused problems unless you open them up !

Clay, do you have dies or have you tried forming one? I’m pretty interested in this but not sure how easy it would be to push the shoulder down that far on a 6BR case. Seems like it could be tricky to anneal far enough down the body and I’d hesitate to try it without but maybe the concern is misplaced.Clay, it sounds more like Harry Rowalds dinky dog. he shortened it a bunch and shot ultra lite 6 mm's like 56-60 gr area. it shot fairly respectful as long as the conditions stayed easy. I'm not 100% sure on the base case but think it was a br
George, you likely nailed it.
I just measured the volume of a PPC case filled to the rim with 133. With my pour technique and my funnel it measured 31.34gr. Using the same powder (the 31.34 charge that came out of the PPC) and pour technique, funnel, it over flowed about 5 kernels of powder.
I deduct the volume has to be very close to the ppc. The Dinky Dog case I have is Norma brand and base to shoulder is exactly the same as a Dan Dowling's Waldog case.
I may dabble with this a bit more, just for fun.
Thanks

Virtually nobody annealed when the case was designed. Although, it make it easier.Clay, do you have dies or have you tried forming one?
