[TORSTEIN]

It`s hard to work in the dark, not having the gun and components in hand.
If you will be my eyes, we give it a shot.

I think you have one (or more) of the following problems:
1. Reloading
2. Headspace not to spec.(case)
3. Headspace not to spec.(gun)
4. Parts out of spec.

We will make a dummy round(only one).

If you have the Redding 3 die set, take die marked 300/221 REM NK M3 and hide it. Do not use this one in your AR.

Use FL die marked 300/221 REM FL M3.

If possible use single stage press.

We will not follow the Redding instructions for this one.

Work with new 221 rem case, if by hand.


FL DIE
Use 270 tapered size button. Adjust it so the decapping stem is 3.0 mm out of the die.

Move ram all the way up and hold tension on the handle.
Set Fl die against ram.
Lower ram. Adjust die in 1/2 turn.
Ram up+tension. Lock the nut.
Look between ram and die.
Note where the contact point is.(see some light/no light?)
Lube case.
Insert case. Ram up+tension. Is the contact point the same?
If so, move on.
If not. The tapered size button butt against the "floor" of the case. Back it up some and repeat test.

Repeat all of the above with .30 tapered size button.

Trim case to 1.30"
Chamfer inside&out.


WHAT IS MY C.O.L.???
Close the bolt. Take yout cleaning rod(not the threaded open end, but flat end) and insert it from muzzle end until it touch the bolt.
Mark rod at muzzle. Remove bolt assy.
Insert bullet of your choise in chamber. Hold bullet against rifling with a pensil. Insert rod. Mark at muzzle.
Difference between marks is max C.O.L.
Subtract 0.1" from this measurement. (For use in this test only)
This is what C.O.L. is for test


BULLET SEATING DIE
Ram(with case) up+tension. Adjust die down until you feel a little resistance. Back die up 1/2 turn and lock it down.(=no crimp)

Insert bullet to C.O.L.(for test)

This is your dummy round.

What would I say next???
Run to your gun and.......
NO NO NO.

Pleace do not do it.

Wait for me.(more instructions. He he he)

Post when ready.

Have a nice day.
