Your definition of compressed load

I have to use a drop tube with my .223 load. 27 grains of H4895 doesnt want to fit too well otherwise. I also use a drop tube with my .221 Fireball load. In both cases, the bullet does make contact with the powder. There is no crunching, so I dont consider it too compressed. The 55 grain Vmax in the .223 load does stick down into the case a bit.

ok, loading up a new batch of 25-06's tonite and since I have no real data in my manual for Accubonds I had to get some data off of reloadersnest. Well, as as I approached max load I looked down in the casing and noticed that the powder was just starting to creep up into the neck at 57 gr of IMR 7828. Now I didnt hear crunching when I seated the bullet, but there is no rattling sound when I shake it. What is a true definition of compressed???

I would think it would, on some theoretical level.. in all practicality, there's a lot more factors that go into it. Otherwise, we'd be sitting at our benches, hand mic'ing and weighing each individual kernel of powder.

If you are using a 120gr bullet, you are compressing the load. The current IMR data shows the max load at 55gr=3105'/sec.

Do we even want to start about the difference between "compacted" vs. "compressed"??? Yeah, i realize the loading manuals don't mention compacted, but there IS a difference-----

Compressed?Thats when you fill the case with powder, poke it down with a stick, and then dump some more in, isn't it? Kinda like with them muzzleloaders. Fill the barrel with powder, then poke it down with that little stick they give so you'll have room for the ball.

Im loading 110 gr bullets, 57 is max load for that grain.

well, this is the reason I asked this question. I didnt even really know what compressed was. I kinda thought compressed meant you heard stuff crunching when you seated the bullet. So no, I dont know the difference between compressed and compacted.

Thanks, Rebel, for the Webster approach. I've been away for a day and didn't get to spell this out. Ol' Mr. Webster further describes "compress" as "to condense". Back to " condense ", it refers to changing of gases, to compress, to reduce in size or volume and pack into smaller space".
With all that being said, I feel that unless we are altering the physical volume of the powder compared to it's weight, we really are not compressing it. What we PROBABLY are doing is compacting the charge, and if some of it gets a little smashed in the process, so be it. Stick powders are probably the ones that fall under this characteristic more than the ball, spherical, or flake ones, due to the lesser amount of air voids between the individual particles in the non-stick ones.
Anyhow, using whichever term you wish, I'm sure we all understand what we are talking about--------??????
