I'm seeing ones that have a micromiter built in. Are they just for changing AOL or do you use it for seating also????

I'm not sure I understand your question. The seater dies with the micometer click adjustment knobs (like RCBS competition dies) are for precise adjustment of bullet seating depth; which, in turn, changes the overall length of the loaded round. They work pretty well.

Mr L. I bet you are talking about Redding and RCBS comp dies. Top notch dies. I love em but won't pay the price for em. If you measure 3.7" COL and want 3.6", those dials for adjusting are dead on.

It replaces the the screw and locknut on the typical dies.

I seen this guy out at the range and he was shooting 5 shot groups with his press with him at the range. He was seating the bullet a little deeper for each 5 shot group until he found the right length. I was wondering if this die(competition) would work better for this????

Holy cow load development at the range. "hey jim", that shot pretty well, press me up a few more of those.

Thats pretty cool.

No, you can do the same thing with your regular seater. I mean don't get me wrong, those Redding' comp seaters are the cadilacs of seaters. You got the flow, do it. Very nice. But not entirely needed.

Now you really need to show me some turkey woods.

BC were abouts do you do your shooting???

I don't see any point in the micrometer adjustable dies.

If you have your lockring set so that your die screws in to the same place every time, all you need to do is a litle math to adjust your seating depths.

The seating plunger will have a 20 to 1 thread pitch, meaning that for every 20 turns, it will move 1 inch.

For every turn, it will move .050"

1/2 turn = .025"
1/4 turn = .0125"

Of course there will be a bit of error when the locknut on the seater plug takes up the slack in the threads. This is why I make a reference cartridge for each rifle/bullet combination. Seat a bullet in a sized piece of brass to the length that you want, and use this to set up your seating die in the future.

I agree just a convienence. I mean if you want to go thru the trouble there is no point for buying a dillion over a lee 1000. A little care and math, whatever, you can do the same thing. Its just the quality and convience over the lee. Make sense.

Its our hobby, we go overboard.

Actually when it comes to bench rest seaters in a press, i've always liked the Bonanza BR seater best. It just plain seats the bullets straighter.

Many of us use to work up BR loads right at the range, back when i shot a lot of competition. Some guys set up just off line, others had a camper with everything in it. Other guys only had a handfull of "matched" BR cases, and used spl. hand made "pound in" BR dies, and loaded the same cases over and over right on the bench.

These days i have a range right off my shop, so i can load and fire from the same room.
