[QUOTE="martinakl, post: 2288777, member: 74115"] I used a cleaning rod to measure the twist rate. It came in at 1:10 multiple times. If you go to build a S20 on SAKO’s site, it says it’s 1:10. The new, 2021 Tikka 300 Win models are now 1:10. Inside the barrel is labeled “300 WM 10.” the barrel marking is what made me research further and try the cleaning rod trick. Not 100% sure the “10” is the twist rate marking but it seems plausible? I’ll have to find a load and go long to confirm no drop in BC from advertised. Or, keyhole’s in targets at extended ranges. I’m also going to try some 230gr Hybrid OTM’s through it next outing. I’ll also be testing Retumbo, N568 & N570, Ramshot LRT. [ATTACH=full]298509[/ATTACH] [/QUOTE]
