Sako trg twist rate by serial #?

[chevytruck_83]

I’m interested in a used sako trg 42 in 338 lapua. The gentleman wasn’t sure what the twist rate is but he was kind enough to give me the serial number. Can I tell by the serial number what twist rate it is?

Did you get a reply to your question ?

if he never changed the barrel you can tell by caliber

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

there’s a remark on the barrel says 10” . That is my question . This one is produced in 2016 i believe

 

[Lowlight]

then you have your answer,

if you have the rifle and a cleaning rod you can confirm it in two seconds

That is correct , thanks
