Powder check die rec.

I use a Hornady Powder Cop die in my LnL. I like it. I also have a LED book light from Dollar Tree clamped on the die so that it shines down in the cases so I can see the powder better.

I prefer the RCBS Lockout Die best.

I have the RCBS lockout die and it works really well.

IMO if your concentration isn't that good, you should probably not reload.

I have the RCBS. It works well.

I use the Hornady Powder Cop die. With it you can use it for pistol or rifle. I have a light I put over the center hole which lights all the stations up. With the auto indexing of the LNL-AP just make sure you do full strokes and double charges will be non existence. If you have a jam, clear all the stations. Then deal with those at the end.

Another vote for the RCBS lockout die.

I prefer the lock-out die as well, but I also look in every case and state clearly that you should visually inspect every case as well. Take the case out and look in it if you have to (probably shouldn't have to since no one else has to) but you really need to keep that as part of your loading practice.

And if you really think you can't see your charges well you can always consider being sure to use powders that fill more than 50% case volume per charge since it makes doubles more difficult to miss (not squibs). But be safe. If I couldn't load safely then I would probably need to stop loading.

I simply would not reload on my 650 without the lock out(pistol) or the Dillon beeper(.223 rifle).

It has nothing to do with concentration, it is simply a safety redundancy that doesn't hurt a thing, and doesn't slow down reloading. It is a no-brainer.

I bought one of these a few months back and have been happy with it:

Also, like ColtPythonElite, I have an LED light attached to my press so it's easier to see down inside the cases.

I made these changes after I had a squib load and had to tap a bullet out of a barrel with a wooden dowel and a rubber mallet...

I loaded 50 rounds on my LnL when I first got it.
I then stopped until I ordered and received an RCBS Lock-out Die.
I like it because it stops the entire loader until you find and correct the problem.
They are somewhat expensive and being a cheapskate I do use the same on of all calibers and just change the foot ,if necessary,and adjust it when I change setups.
It is just another step in maintaining good procedures.
I still have a light on the press and look into each case (hopefully).
Money well spent.

I have both the powder checker and the lock out die for straight wall cases. I will not load on a progressive press without one or the other. In the beginning I used the lock out die on the Piggy Back and Piggy Back 11 presses. The Piggy Back press has 5 positions meaning it is possible to seat on one position and crimp on another. My Dillon 550 has 4 positions, Dillon suggested seating one position and crimping on another, that eliminates the powder and lock out die. I insist on using the powder die and lock out die so I seat and crimp on the same die or crimp after loading,

Then there is the discipline reloader, weigh the cases and match, weight the bullets and primer, after loading weigh the loaded rounds, any difference in weight has to be the powder. I loaded 250 30/06 rounds, when finished there was 17 grains difference between the heavies and lightest, The difference in weight was caused by the difference in weight between the cases.
