Hey guys I just got in a new to me 3.1 with IV core, unfortunately it did not come with the soft tip bolt but the hard tip shoots amazing. Anyway I was wondering what are the optimal screwed in settings for the core? I talked to the seller and he said he was running like 8 turns in and to me that would seem incredibly inefficient but I really don't know because the IV didn't come with the manual. Thanks in advance for the answers. As it sits now its shooting buttery smooth so I really don't want to mess with it but more of a curiosity question.
