Seating depth. 223

[johnnyjr]

Got to wondering what some of you use in your 223 rifles. I usually find the best,with the bullet just touching the lead.. I had one of my mold shaved off today. Removing the gas checks. Took .070 off. All my 223 molds are gas checks. Couldn't find a plain base. So, now I have one. Anxious to see how it's going to work out. .. it also is going to make the bullet a little shorter,and lighter.. will be interesting....

Most of my rifle bullets in all calibers are seated to kiss the leade, if possible.

I set them up for 2.260 .
Several reasons, mostly for a one size fits situation.

"On the lands" for all my cast bullets! That is where I start to make up my loads.

Is there any reason why you do this. I can see where it might be a good start ing point. Do you leave them touching or start backing off a little at a time

 

[JWFilips]

I never back off. I build up the load to shoot this way. I get my best accuracy without a jump using Low Node ....no reason to change

 

[johnnyjr]

I'll be trying that as well. Thanks for the reply..

I make up a dummy round to gage the depth! I take a case and make 2 or 4 slits in the sized neck with a jewelers saw; then insert a bullet way out and put lube on the bullet so it won't stick. & very carefully put it in the gun and slowly chamber it with the bolt closing. Once closed I open the bolt and carefully catch the round in my hand. Measure it! That is the exact depth & that is what I use.
Alternately I have seated the bullets out long on the loaded cases ( I never crimp for low node) and let each cartridge seat by themselves with the closing of the bolt! I do this a lot with 30/30 and smaller cartridges

You're gonna breech seat them with the primer anyway, might as well make them touch or -close to.....unless you have an AR-15.

OAL for the cartridge is very dependant on the indiviidual rifle. That being said, I with JW Filips & CZ83x62 on this. I start as close as I can to the lands.
Now, other factors often intervene, mainly the magazine length if the cartridge needs to feed from the magazine.
Also, there's a limit with bullet designs and case necks that make this process more of a default to the cartridge than a seat as long as possible event.

I don't use the magazine,I single load.. thanks for the info. I need warmer weather. 8 degrees is a little to cold. Johnny

Now today while loading a few cast bullets to try,I found I can seat them out farther if I size them .224 instead of.225.
So I'm going to try.224 first. These are bhn of approximately 8. Powder coated. Using 3.2 gr. Of wst.

 

[JWFilips]

I too load one shot at a time in all my rifles for target shooting. More consistency of the powder in the case.

 

[fiver]

hmm powder coated and 224,, yeeap.

let e'm jump anyway, that little bit of powder with a fast rise speed isn't gonna matter, you got nuthin to manipulate.
magazine length is good nuff.
if your gonna jam them you might as well do it in the leade with the body where it's supported as with the nose that touches further down the line.
maybe straight maybe not..

Powder coated is a totally different story. Load them like jax.
