The HD5 has lockable turrets,have to pull them up to adjust then push down and there locked and secure like Fort Knox..............Jr Solocam what caliber is your going on ? Mine is a 6x284 and its also plenty flat shooting.
Going on a lightweight 65-284. The scope will get me past 750 which is all I want out of that rifle. For under $1000 I think the HD5 will compete extremely well.
