Hi , can someone tell me if the 10” indication on the barrel refers to the twist rate ?
because in the manual it states 1:12” twist rate

The .300 Winchester Magnum chambering also has a non-traditional 280 mm (1 in 11 inch) or 36.7 calibres right-hand twist rate.

For the .338 Lapua Magnum chambering a non-traditional 305 mm (1 in 12 inch) or 36.4 calibres right-hand twist rate was selected to optimise the rifle for firing 16.2 gram (250 grain) .338-calibre very-low-drag bullets. As of 2009 .338 Lapua Magnum barrels can also be supplied with a 254 mm (1 in 10 inch) or 30.3 calibres twist rate optimised to stabilise longer, heavier very-low-drag bullets like the Sierra HPBT MatchKing and Lapua Scenar .338-calibre 19.44 gram (300 grain) bullets. The traditional 254 mm (1 in 10 inch) has since become the standard twist rate for the .338 Lapua Magnum chambering

I am almost certain it does. I have found photos of known older models that do not have the 10” stamped on the barrel.

Do you have a picture of the trigger group? the trigger was changed in 2013. If it has the new trigger then it will for sure have the 1-10. Some rifles will have the 1-10 and the older trigger as well.
