Pressure rating on a Swing Top 750ml bottle

[Thefatdoghead]

Im sure its been asked before but I cant seem to find anything and my internet is really slow.
Just wondering if the brown 750ml swing top bottles will hold 3 to 3.5 Co2 volumes safely?
Cheers

Most likely answer no. Go champagne or Belgian bottles to be on the safe side

Got the answer off Martin from NHB. Apparently the seal will lift at 3 volumes but the bottles could take it. I'm sure the Mrs likes champagne
Ill use the swing tops for my dry mead.
