I am chasing a 600 OK case and a 4 bore case for my collection. (I am looking into getting a 600 OK built on a Brno action). Who sells these cases? I was just after one each.

Call ED Plumer at AHR he has some .600OK brass and is equipped to send them out.-Rob

I can get you one of our newer style 4 bore
cases, with a 2000 grain bullet in it.
It won't look like the older 4 bore cases
with larger diameter rims. and ours has a
small groove ahead of the rim.Picture
below shows case and bullets.Two on the
left with bullets, and 3rd the case we make them from.Ed

I have just ordered a 600 OK case from Ed Plumer.
Hubel 458 ,do you have any of the original style 4 bore cases? I was after one of the original style cases if possible.

cr500- No I don't.. saw one sell on web for 60
bucks.There is some in Aust from Imperial cartridge, for the 4 bore pictured on here
a while back, but don't know who to get them from.
Check with Rocky MTN cartridge as he built some like the older styles for people, and he built the 4 bore TULA case for AL and others. That is a short 4bore you need in collection also,
which he was.307-587-9693..Ed.

Thanks for the input. I have ordered a 600 OK case from AHR and a 4 Bore case from Rocky Mountain Cartridge company.
The 600 OK will be my next project and a 4 bore a dream for the futute.
