luv2safari; All,
IF I found another O/U 2400 & with a .222REM barrel, it would be rebored to 5.56NATO quickly OR (more likely) it would head to Jessie at JES to be reborn as a .257 Roberts or 7x57mm Mauser, as .the .222REM isn't often available here in South TX. - I'm sure SOMEBODY routinely has it in stock but seldom is my guess.
Note: IF a .222 is rechambered to the NATO cartridge specs, it can SAFELY fire both .223 REM & .5.56NATO. = YES firing the NATO cartridge in a .223 chamber IS DANGEROUS.
NOTE: IF you have a Model 2400 in any caliber OR one of the similar combination guns that is branded as a VALMET that you wish to sell, please PM me with photos/price.
yours, tex
JES can't rebore combo gun barrels. I asked him about it several years ago. If he could I would have a 12/9,3X62.
If he is set up to do them now, someone please tell me.
