I have to say if you are relying on bulky powders to ensure an under or over charge then you should look to your reloading procedures and add steps to verify each charge.

Trailboss is bulky all right but other than that it is just another fast powder but is damnably expensive and has its performance limitations, if I am looking for a bulky fast pistol powder then I find Red Dot or 32C far superior powders. As I use other steps to verify my loads, visual and mechanical, then I am not restricted to bulky powders which have their limitations in the larger cases where an over charge is still possible as it is designed primarily for low power loads in pistol calibres for CAS loads.

Doesn't everybody squint down their cases with a torch between adding powder and seating bullet to check that powder level looks the same?
Best way to avoid the above trauma and squib rounds.................

You would think so but given that some manage to prime with the primers in the wrong way round and then fire them.....

Not really a viable option if you're using a turret or progressive press though

Quiet viable on both my progressive and turrets, cases are easy to remove.

There are also mechanical verification dies available or it is easy enough to make your own version.

I'd be interested to see any tool that verifies every case/powder charge that works on a Lee turret press without removing every case from the press during the loading cycle (as that would defeat the object of using it) I do have a spare 'station' on mine as i prime cases separately

I guess the Dillon powder check isn't going to work without modification or some engineering, but the Hornady Powder Cop and RCBS Lockout dies appear to be universal. Have you looked at those?

I use a Lee turret press and have done so since they were introduced. Cases are cleaned and primed, then loaded into a tray where they are filled with powder. The full tray is scrutinised under a strong light to verify that powder levels are the same. Only then do the cases go into the turret press. In the early days, I tried priming in the ptress and using a powder through die. This led to prblems with upside down primers and powder "bridging" causing rounds with primer only. The method I use now is quick and foolproof.

I've used the same Lee Pro 1000 since the mid 80's when I first started reloading for handguns... for .38, .45 and 9mm.

I use it as Lee intended, cleaned cases put in the plastic tubes, first station sizes and de-caps, 2nd station primes and dispenses powder, 3rd station seats and crimps.

Yes, the priming does go wrong sometimes and I do get the occasional sideways primer... (not normally upside down though)... the best solution is to make sure the chute is always full, once you can see the last primer at the top, refill the container.

I've never had a problem with the powder-through die, although over the years I've only used smallish (3 to 6gn) charges of Bullseye, Red-dot, Accurate #2 and currently N320, so not much chance to bridge..

Haven't seen those before, look pretty simple to use and incorporate into a turret loading cycle
