Good video, I agree with what he’s saying and I would say all of what he is saying is going back to fundamentals in Marksmanship, Loading your ammo, load development etc.
But do all the extras like cleaning, batching brass and bullets by weight etc give that noticeable or in fact imperceptible edge that gives you the extra accuracy/consistency your chasing over just getting what I would say are the fundamentals which is what he describes in the video.
I don’t know, If you are enjoying the shooting it’s all good.
If your getting stressed and pissed off over it and start to loose enjoyment because of chasing the elusive perfect load which in fact could be just an error in another aspect of shooting maybe that’s the point at which you say ye all this extra effort in regards to loading isn’t really worth it and just stick to the basic stages.
That’s unless you sadistic and like to punish yourself then chase away.
