This is why i load one case at a time. Prime all. Then one by one, weigh in powder then seat bullet. Next case...
Might be slower but at least i have piece of mind.

Seen the results of exactly the same thing back in RSA in the old days - rifle also stopped working on the second shot.

Shooter brought it back to the shop to complain that the bolt wouldn't open and why had the bottom dropped out of the magazine and why had the stock cracked on both sides of the action?

The gunshop tried to make the shooter look guilty, but I thought that since the guy came in asking for a 308, admitted he knew nothing and they sold him a 270 and 308 ammo, that it was their fault, but ....

Another one was written up in an RSA magazine called Magnum - a guy fired a 308 round in a .25-06 with regrettable results, and the shooter lost a few fingers IIRC - the front stock shattering.

Then, here in Oz - it happened twice in one day at two different clubs I was a member of - in the first one, a laddie let off two rounds of 7mm-08 in his beautiful Beretta O/U Double rifle in .30-06 - result - mainly embarrassment and funny straight-walled cases.

The same day, I popped into another club and one of the shooters was complaining that his Sako Quad was shooting crap - he didn't know what was wrong - all his 17-HMR cases were blown out and split - it happens if you have the .22WMR barrel on, it appears.

I do things differently - after preparing cases and trimming and chamfering, and so on, I put them mouth up in a loading block- then I prime them all, with a hand primer, returning them to the block, neck down, with their newly installed primers showing to the gods and me.

Then I charge each one individually, returning it to the block, mouth up. When all are done, I use a torch and check that each one contains powder and is the same height - any doubts and I empty the powder and reweigh.

Then I seat each bullet returning it to the block bullet down again.

It's not what everyone does, but it's been my habit since the early 1980s and it's worked for me.

Obviously powder can also be a trap, I tape down container lids with white duct tape and write caliber on that.

Thats what i do BRNO... :thumbsup: ...except the bullet down at the end....no real need for that as the bullet itself in the neck is enough confirmation of the final step being complete.

Yep, I think it's a form of Time and Motion Study. How can I do the most with the fewest actions?

That's the way it turned out for me, so it's not really surprising that others would develop it as well.

BTW - the reason I put the loaded rounds back is so that, when I put them into the box, I can give them a final inspection, and maybe a rub with a cloth. Then I know I've inspected them with my mind on the task of inspecting, not chopping and changing tasks from weighing to seating to inspecting. It's the way MY mind works - others may do things differently and if it works for them, it's really no skin off my nose.

I’ve been in the metal trades most of my life, so I’m used to being organised in processing and production work, where you put everything through the one process, then the next after that. Keeps it simple

Your are right that we do it a particular way because that's how our minds work.

In my case, I have a brain injury that means my short term memory can be unreliable, so I build one bullet to completion at a time.

I start by priming all the cases I'm going to load and store them in a block, nose down, so I can see they're ready to start. I count out a corresponding number of projectiles and put them on a little tray next to the block, then I take a case, weigh the powder, charge the case and seat the pill, give it a wipe down and final inspection and that is one I know has been completed and is ready to fire. That also eliminates the need to have charged cases lying around that I need to re-check or with my wobbles and twitches, might knock arse over and need to redo, everything is done within my goldfish sized short term memory span.
