H series long action question

[colt56]

I picked up a H series long action in 7mm mag. I am wanting to build a hunting rifle and wondered if there any disadvantages to building on that old of an action? It seems to me back in the day folks complained about savages and I wondered if that had anything to do with the old actions. I am putting it in a manners stock so don't want to put a iffy action in a sweet stock. My other builds have all been on J series actions and shoot lights out. Let me know guys thanks
