Honestly for priming I would recommend a hand primer (Lyman, RCBS, hornady, whatever) to anyone using a single stage press. That'll save you a ton of time and isn't really expensive. I prime while watching tv, so it's essentially time-free.
Steps:
1-Clean brass if not new.
2-Resize brass.
3-trim brass if needed.
4-clean again if needed.
5-prime using hand-primer while watching GoT or hockey game.
Then you have a large batch of primed cases ready for loading. The larger your batch, the more cost-time-effective you get because you don't sawp between operations.
And yeah, the breech lock system is great. The breech lock adapters are really expensive considering what they cost to make, but they're very convenient.
