First, a warm welcome to HuntChat.
The Lyman manual is very god, because it is independent: neither a bullet nor a powder maker.
But it should serve as your "fail-safe" manual, to double check the loads you find in the bullet maker and powder maker manuals.
I always recommend that reloaders check with the bullet-maker's manual first because the bullet has SO much influence on peak chamber pressure. Cross-check those loads with the powder company, and if you find much discrepancy, then fall back to your faithful Lyman manual. But if there's little difference between the bullet and powder data, go with the bullet maker's loads.
Again, welcome aboard!
