the number at the back in the circle is 270 I think.

I assume here you are speaking of the elongated C. If you examine it real close it probaly reads 12-70.

you are absolutely correct it does say 12.70 inside an elongated C.

Thanks and I hope that means 2&3/4 inch chambers.

any luck with the chokes????
