Charging with powder ,checking fill level,and seating bullets require focus .No distractions.
But I agree,other tedious ops can be done in leisurely fashion ,couch,back porch,or catfishing.
Decapping . Then tumble.
Its not the greatest press for sizing,but it works anywhere..Then I cob tumble the lube off.
RamPrime will work,low volume,but I prefer the RCBS hand priming tool.
Easy as eating pistachios.You can do it at the lake.
Its nice sitting down at the bench with a few hundred primed brass if you are a single stage loader.
Charging and seating is the fun part,and its easier to give your best focus to those operations when you are fresh.
And there is something about my fake Krag carbine that makes me want a hand tool.A Lyman 310 would be OK,but the Lee has advantages.
