That report leaves me with questions .What was the composition and what were the specs that it was supposed to be?. What was the hardness and what was it supposed to be?. Just exactly what were the 'striae'? [mechanical scratches , tears ?] High sulphur steels like 416 are not recommended for much cold working. Did the button rifling process produce microcracks in the bore ?

Anyone hear more of this story??

I was given a letter to read yesterday regarding MAB having a barrel blow up.
It was a stainless one in a .308 fullbore rifle.The NRA have now banned MAB s/s barrels from all Australian ranges.
The steel was checked and found to be very soft???? The steel came from a steelworks in Taiwan.The specs stated the steel was harder than it in fact was.Also contributing was a worn cutter which made the barrel constrict also leading to the blowup.Another barrel was found to be soft but wasn't fitted yet.
MAB have no records on where the barrels went and from which lot etc.
All the above is fact read from a letter with a NRA letterhead.

Whisper is Bugden has done a bunk to New Zealand.

I think this is old news, unless another barrel has come apart? Details can be found on the MAB website. It will obviously do MAB no good publicity or sales wise. Wonder if they'll do some discounting to get their reputation and sales back up to scratch. Need a new 358 barrel

Thanks Con.I found some more info out there.

If MAB cannot prove the quality of their steel they should be testing every barrel that went out the door at their cost!
If they are unwilling to do this they should be offering a full refund to anyone who has no confidence in their barrels.
I would be demanding a full refund or legal action will be taken.Simple as that.
