bullet jump

I just got into reloading and have an AR10 (308) and AR15 (5.56) and was wondering if anyone has had any luck in regards to accuracy by adjusting bullet jump, or if the magazine is enough of a limiting factor to where length of the bullet seating depth to the leads would make it not be worth it...

How far of a jump are you guys running these bullets? I am hoping to propel these with H1000 and I want to mag feed but it ends up being a jump of about .150”. Haven’t shot any yet but I just wanted to get an idea before I start burning powder. Thanks!
