Just booted up a new game in 3.10 and the issue persists - accuracy for 5.7 weapons is lowered by 10% with any ammunition type, making the 5-7 and the P90 less accurate by default:
hub.sp-tarkov.com/attachment/9780/ hub.sp-tarkov.com/attachment/9781/
7.5 MOA -> 8.25 MOA with SS190 (which should have no impact on accuracy), 7.5 -> 7.5 MOA with SS197SR (which should have an accuracy bonus of 10%)
This is not the case for other guns where accuracy is calculated correctly:
hub.sp-tarkov.com/attachment/9782/ hub.sp-tarkov.com/attachment/9783/
Again asking if anyone can confirm the issue, any help (apart from: JuST ModIFy tHE aCcUracy YourSelf as iexistggrsd "suggested") would be welcome. Confirming this would take you what, five or ten seconds at most?
