I hardly see the point in chasing 1 fps consistency in powder charging when a half-grain difference in water capacity between cases will net you about 10 fps in variance---and I'd be surprised to see a variation in a lot of 20 cases less than 1 grain. Throw in neck tension variations, and the...
If I'm only loading a dozen rounds or so, I'll go ahead and just use the Co-Ax priming station. No doubt it is positively consistent, but it IS slow going. I use my RCBS hand priming tool if I've got more work to do.
A little unsolicited advice...you won't get a good burn with 7828 and your velocity spreads are likely going to be all over the place. Smokeless powder is meant to operate at certain pressures and when pressures are low, performance generally suffers. Using a burn rate that's too slow can even...
I personally have no fear of pushing the .30-06 beyond SAAMI pressure specs, but you might possibly get into trouble with IMR4831.

It looks as though you couldn't possibly get enough 7828 in a .30-06 case to get into trouble.

I don't believe I've ever shot at a range with cages for the shooters.
I do notice all the bullet holes in the wooden partitions. :shock: That represents an awful lot of ADs, or some downright disrespectful shooters!
Well, wait a minute. You say these were fired in your own rifle, right? So, is the photo before resizing, or after? If they look like that after firing in your rifle, then I would suggest you need to take a good look at your chamber. If they look normal after firing, but take on these dents...
One thing's for sure....they are curiously uniform in shape. And that one at the bottom sure looks like SOMETHING is either in the sizing die or the chamber, whatever the case may be.

As I understand it, if you're doing this for OBT purposes just close the bolt on an empty chamber then stick your cleaning rod down the bore and put a mark on the rod right at the muzzle. Measure the rod from the end to the mark, and that's your barrel length.
Okay, that actually gave you a bit more headroom, I think. Here's what QL thinks:

I agree with Scotty wholeheartedly.
I've read through this thread and did not see any mention of an actual water capacity measurement. It can make all the difference in the world. Case in point: that slick new 70 Super Grade I snagged a couple of months ago? My load for the older .280 pushed a...
