    While overloads can be a problem, underloads can also be a problem. My brother was trying to make some light loads for a 45-70 trapdoor and the gun came apart. He was using RX7 with a load under the recommended starting loads and a light bullet. It took about 4" out of the middle of the stock, the chamber end of the barrel looked like a banana peal and the top of the action was gone. The breach block was still in place. Luck was with him as he was OK. The gun had a new barrel and had been shot many times with factory ammo. Only case of detonation that I have ever seen personally. He had the barrel pointing down when he loaded it and raised it then shot so all the powder was near the base of the bullet.

    He had a barrel obstruction.

    I batch charge cases and shine a strong light it the cases to verifie that each case shows the correct level before seating a boolit. I have reloaded since ~1970 and still have both eyes and all my fingers.

I have also had occasions when I have realized the poise on the balance has moved. When did that happen? How many of those loaded cartridges are off weight? Hence my general preference for powdering a group, checking, then seating.
    And that right there is why I generally batch load. Usually 25-30 at a time. Except for hunting rounds. For those, I have the powder measure drop slightly light, then trickle granule by granule into the pan, till the powder charge is exact. Then the powder goes into the shell, the bullet gets added and then round gets completed.

    One needs to use a procedure that works for them.

    But I will make a comment. If you can't maintain enough focus to load a 50 round tray, you may have issues loading one at a time.

    Not hatin', just saying.

    My amendment can beat up your amendment.

    I use a slightly different method to prevent a no charge or double charge. I check the cases inside and out and then prime. When I put the primed cases in the loading block I place them upside-down, i.e. mouth down with the primer up. I weigh the powder charge, take a case from the block, put the powder in the case and set the case in the loading block with the neck/mouth up. When I finish placing the powder in the cases I check the level of the powder in the cases visually. If I see something that looks like an under or over charge I investigate. So far this has prevented any problems for me.
    BIG OR SMALL I LIKE THEM ALL, 577 TO 22 HORNET.

    I ,and many others was caught out by erratic deliveries from a powder measure.....I suppose more correct to say ,caught out by relying on a powder measure to be accurate.

    In case others are doing this in order to get by or extend their supply of lpp be warned. I’ve recently started using small [using both rifle and pistol] primer .45acp brass loaded on a Dillon 550] and have had dead primers stick on my decap pin and then get pulled back into the pocket and reseated by the new primer. Of course when I advance the shell plate I see the new primer in the cup which alerts me to the reseated dead primer. If I back up the plate and lever it again the primer will cooperate and fall out BUT I’ve just double loaded the case that was under the measure. When I have a sticky primer i remove the case, advance the plate and redo the odd case again. Be safe out there.
