question about factory load
 

picked up some Remington .243 win 80 gr. psp ammo
and some of them i can shake and hear powder moving like it is not full.some are full. i have also noticed this other calibers i have owned.

are these not loaded properly ?

i'm not too informed on the subject of ammo and i just spent $1400 on a coyote set-up and i want it to be right ! i'm thinking they won't be consistant from round to round.

i just bought the cheapest to get the gun sighted/broken in and them plan on shooting a better cartridge/smaller bullet.
THANKS 1

Shoot them and see.

As a reloader, there are some rounds that don't completely fill the case with powder after the bullet is seated, and you'll hear the powder if you shake the round a little.
Theoretically, it hurts consistency in accuracy, as there can be a slight variance in the combustion pattern if the powder is spread differently from shot to shot, but I'm not a good enough shooter to detect the difference.
I know that in my 300WSM, my favorite load is slightly less than "totally full", so I have a small air pocket in every round. If I maxed out the load, I'd have a compressed load, IE the bullet would compact the powder when I seat the bullet, which, in theory, promotes better accuracy.
Is there a difference? I don't honestly know.
Would I worry about it for hunting purposes? Nope.
I think that the difference in accuracy wouldn't be readily detectable until you're reaching out past 300-400 yards, which in a .243 is at or past the range which I would take a shot at any animal.
If you're shooting competitions at extreme range, you may want to reconsider your load, but for yote hunting inside 200, I think the difference is pretty negligible.
You be the judge.

the powder doesnt always settle the same from load to load. before seating a bullet ill tap the side of the case to help things settle a bit.

Do you have a scale? If so, weigh them and see how much difference from case to case. Shouldn't get more then a couple of grains from case to case unless there is a difference in powder. Not surprizing with cheap factory ammo. I've gotten picky since I started reloading. :)
