Observation on Compressed loads

[Geno]

I've been noticing that several load manuals show starting loads that are compressed. Obviously then the Max loads are REALLY compressed. And since Bullet seating depth has a suggested value but tends to differ to some extent with type of firearm and bullet make being used. Wouldnt pressures be pretty darn erratic? The whole pressure curve graph and theory would be all over the place. In fact, what caught my eye to this was a minimum load once that wasnt too far from filling a case (well, part way up the neck anyway). I started wondering, how does anyone get the max loads in the case in order to compress it in the first place? I've since moved on to better powder selections and avoided the whole compressed issue altogether, but still I get to wondering about this. I have visions of a guy sitting at the bench stuffing and tamping powder in the case until the correct amount is in, then cramming a bullet down on top of it all. I guess I'm too scared to play around with that, but seeing it in manuals gives a guy an idea that its ok. If anyone was wondering, I've seen this with .223, 7mm TCU and .44 mag.

I once loaded some 222 loads that were "compressed". You couldn't just drop the charge in the case or it would spill out over the top. When I droped the charge I had to tap the side of the case to settle the powder into the case enough that it didn't spill over the top. It would just settle a little below the top of the case. What a pain in the butt. I'm with you on this one, find a powder that not a compressed load. Its not worth the trouble.  KN

When loading compressed loads, always remember to use single based powders. Double based powders give bad performance and can be dangerous because it is aready so compact.

I have one load that is compressed in a 223 contender using varget.It is my most accurate load.To get the powder in i bought a small vibrater from an XX store and hold it to the case.This load would normally be very compressed but this shakes it down very even and tight.I heard my wife tell her mother one time you never mess with a guy with 40 pounds of powder and a vibrater.P.S.I think the purple ones do a better job.LOL
