I like a 95% or higher case fill on my hunting loads and look for powders that achieve that. That said, I have never used loads that has the powder reach the straight part of the neck.
I had some older military surplus ammo. Didn't look like it was a compressed load. The power had coagulated to a state where I had to cut a case open to have a good look at it. Amazingly, it fired unerringly ... just with no consistency. Had to sacrifice the lot, because there was no way to get the 'nugget' through the case mouth.Very common. I've seen this consistently over the past 30+ years of handloading. I'll either rap the case rim on my wooden bench top with finger over case neck, or touch rim against threaded post on my old vibratory tumbler. Usually loosens right up. Occasionally have a kernel or two to loosen with wooden stem cotton swab, and even less frequent a kernel stuck in flash hole.
Of course and you can, you can also get amazing little.bug holes with a SD and ES that's 80fps plus! Doesn't mean it's the right load
I like a load that filles the case but does not go crunch when I seat a bullet.
If I'm at 95% using extruded powder I am hearing crunching. Unless you are seating long I think you're going to hear some crunching above 95% fill.I would say as close to a 100% fill without compressing would be favorable.
So I hit pressure early and had to pull some bullets with 6.5 StaBall powder, all of them were like this and basically had to dig the powder out with the wooden end of a swab, it reminded me of solid rocket fuel. I have never seen this before but never loaded compressed loads with ball powder. Not all of these should have been close to compressed according to Hodgdon data. Its probably hard to see in the pictures but the powder is even tight against the angle of the neck. The ones on the side the powder is not loose it has taken that shape. It took about 5 min per case to remove the powder. It seems ok now but I am considering tossing it in the grass. These were new cases and no lube was inside the case. Anyone deal with this before?
I loaded them a week ago.Do you have any idea how old the reloads are? I would guess that the longer they've been together, the tighter the powder grains fit together. I haven't had to pull bullets on too many of my own loads but I've pulled factory loads that had various things wrong with them. Once a buddy gave me 80 rounds of Winchester factory 7.62 x 39mm. They weren't compressed loads but many of them had absorbed a good deal of water. The outside of the cases were pristine but inside... what a mess! Bullets corroded and 'welded' to the case, powder clumped up. I found (I thought) a solution in that if I could shake the case and hear the powder it was a good round that would fire. Turns out that was only half right. Half of these were FMJ and half soft points, same weight bullets but they had used different powders! The soft points were all ok but used a very fine grained, light grey powder (like AA#2) while the FMJ's used a dark powder (like W748). Most of the FMJ's had this water damage, yet the boxes were in perfect shape. The ammo was a couple of years old, had never sat on the bottom of a lake but had been stored in a basement in an open cardboard box with a bunch of fish tanks! Opps! Like the compressed loads, the powder had to be excavated out due to the water damage. None of the cases were badly damaged but some of the bullets were badly corroded on the base. Weird stuff! They were also very hard to pull, even after seating the bullets deeper. Everything got used except the primers and powder, so it wasn't a total loss.
