you are bound to discover that *some* powders can be very lightly compressed.

The problem with compressed loads is that sometimes they will push the bullet forward over a period of time. This can be a problem if you are feeding them through a magazine...not much of a problem if you are loading single shot.

Dropping your powder very slowly or through a long drop tube will allow it to settle more in the case and you are less likely to need to compress the load.

I shoot benchrest and we use loads so hot that if we drop them into the case quickly they fill it up and occasionally overflow. Dropping the powder slowly solves this problem.

Or wrong caliber bullets.

Or incorrectly seated bullets. A bullet that is seated too short or too long can cause excessive chamber pressures. In a best case, like this one, it only results in a ruptured case and some damage to the rifle. Worst case is a breach failure, which results in bits of metal flying around the room.

Military firearms are designed for this to happen. I have seen the barrel group of an M60 MG go flying down range when a squib got just past the gas port and the following round sheared the barrel. The barrel was designed with a failure point just in case and functioned as designed. No one was injured, only soiled.

What you really don’t want in a smokeless load is that the load density is so reduced that you can get ignition across the top of the powder for the length of the case. Pressures can go up markedly in that instance.

Then how do you load a light target load? With a .38 and a 148 grain wad cutter, you only need 2.7 grains of Bullseye. That's about a third of the case volume.

Usually, if you're compacting the powder, you've accidently double charged the case, and it will go boom. If you're working up a compressed load intentionally, that's a different matter.

Yes, I am familiar with drop tubes to load black powder. No surprise it is done with smokeless too.

I hear what you’re saying. The fast double-based powders like Bullseye and Unique have been around a very long time and seem less prone to low density detonation than some other powders. Some reloaders even fire form new rifle brass using squib loads of the stuff. Reloaders for cowboy action shooting load for low velocity (pistol 700-800 fps) and often use bulky powders like “Trail Boss” to prevent accidental double loads. That should work well for target shooting.

I love my M-1. It's as accurate as can be. Now if I could just shoot straight.

You and me, brother.

With pistol powders, the problem isn’t as apparent. Pistol powders are already fast burning. The issue really arises with rifle powders because you’re effectively changing (increasing) the burn rate by igniting such a wide swath of the powder stack.

Some of the new rifle powders are very slow burning by comparison to pistol powders. In a .223, the issue might not manifest itself in overpressures high enough to cause chamber failure, but in large capacity magnums of .30 cal and up, I’ve seen more than one case failure and one stuck bolt from a “light target load” that filled only perhaps half of the case capacity.

The meta-issue is what you’re effectively doing to the burn rate of the powder.

Can’t find anything on their web site, yet.

All reloading manuals list loads which are assembled with the bullet compressing the powder as the bullet is seated in the case.

Shotgun shells often have detailed powder pressure data, so that the over powder wad (and sometimes the other wads) applies the correct amount of pressure to the powder.

Is this for real? Do we have any source?
