Re: Forster Seating Not Seating

If you don't have a high percentage of bullets causing issue, you can dial in occasional adjustments using shellholders.

If you do have a high percentage of offenders, then it's really time to address a root cause.
After all, you should not have to continually adjust a seater die.

Seating forces need to be consistent and smooth.
You can take your necks to the same & rational seating force, by NOT FL or oversizing necks, NOT 'cleaning' inside necks, and with occasional annealing -with a machine: New Page 1

When I first bought the dies, I sent the stem and some Bergers and Amaxs to fit these bullets.
Thanks for the info.

Provided the stems aren't bottoming out and contact ~half way up bullet nose diameter, they should be fine.

Re: Forster Seating Not Seating

I had the problem 10 years ago with a Forster 257RAI seater, and I had the same prublem recently with a Forster 260 seater.

The concave shape of the seater stem that touches the bullet does not match the shape of the bullet. So a tiny ring is cut into the bullet where the seater does touch it.

To fix this, I take the seater stem out, look at it with a microscope, then spin it in a drill while touching the contact area with fine sandpaper. I am in effect de burring the tiny burr that was made at the factory when the part was deburred.

Other guys do one better, and glass bed the desired bullet to the seating stem, with release agent.

One other thing i forgot to mention. With my 223 die i'm loading for 3 rifles. For some reason every now and then i have to clean and lube the sliding die chamber (plunger ?). I just give it a shot of brake parts cleaner and work it in and out and then a shot of WD40 and do the same.

Re: Forster Seating Not Seating

WD-40 turns into a gummy mess.
Before the WWW there were use groups.
On rec.guns the topic of WD-40 has been beat to death since 1991.
I even called the WD-40 factory.

A word of caution concerning the use of WD-40 on guns. Over time, WD-40
will dry out and leave a gummy residue which can cause malfunctions. I
used to spray it liberally on handguns before putting them away and
found out that after about six months they would no longer work. My
Colt SAA was locked up so tight that it had to be disassembled and
cleaned again before it would fire. Automatics would misfire because
the firing pins would stick. I would recommend that WD-40 not be used
on any gun that is to be stored for more that a short time. Be sure to
keep it out of the internal workings, especially firing pins, unless
you are prepared to clean and relube before the next use. I will say
that none of these guns ever rusted, so it doesn't hurt to wipe down
the outside of a gun for protection. I would also keep it off of wood,
since it will penetrate and darken wood. I now use Break Free CLP and
have not noticed any problems.

Re: Forster Seating Not Seating

I'm going to have to check that out. Acually i'm using LPS spray. It's a non conductive lubricant simular to WD40. Even though you would be suprised at the gunk that comes out of the seater die when you give it a shot of Brake Parts Cleaner. I assume the gunk would be caused by case lube.
