Forster Ultra Micrometer Seater Die

This is one of the best bullet seating dies available. Like the Forster Bench Rest seating die, this has a spring loaded sliding sleeve which is cartridge specific to support the case and bullet within the die body during bullet seating operations

  • This is a threaded die with standard 7/8″ x 14 thread that will fit all regular brand reloading presses and of course the great Forster Co-ax reloading press.
  • Some of the special features about this die is the sliding guide tube to support the cartridge case in line as both case and tube move into the die to seat the projectile straight.
  • There is an adjustment screw at the top of the die for primary or basic setting of the seater stem and the micrometer in the middle for fine calibrated adjustments of the stem.
  • Accurate, consistent cartridge overall length (COAL) results with micrometer engravings in 0.001″.
  • Also the ogive shape of the internal seating stem suits most Tangent Ogive and Secant Ogive (VLD), and Hybrid ogive bullets.  BUT, please read “Troubleshooting” tab above
  • This die is easy to operate and a pleasure to use.
NB: Please follow Forster Products instruction provided with each die for setting up in your reloading press

Stuart’s Tips: fair warning.
We are disappointed to have to say this, but if you will be using Hornady brass for either 6mm or 6.5 Creedmoor with any good seating dies like these Forster dies, and then expect that an internal neck expander resizing system will help overcome the irregular effects of this brass, then you will be disappointed and frustrated for sure. We can’t stress this enough. We feel forced to mention this because we have had to deal with some many reloading problems and complaints about many tools and dies. After buying lots of nice dies and other nice tools like these Forster seaters (or LE Wilson seaters for that matter) and still getting poor results. It’s all because of poor brass. The brass might look good externally but it has very high springback and is particularly tight down in the shoulder/neck junction area. No expander will correct it. It does vary but mostly just springs back to where it was before and the reloaders don’t figure out this out. It is difficult to measure and observe this situation and people reloading seem to just assume an expander type situation will correct it all. But, bullet seating will be irregular and inconsistent and worse with some bullets (particularly if also using Hornady ELD type bullets). Often it will show compression rings where the seater stem contacts (and slips) if bullets are seated deep for sure. There are many other things too which can impact bullet seating tension and pressure, like proper inside case lube. But our advise is this, if you wish to do a some precision reloading and precision shooting…BUY GOOD BRASS. That is is our recommendation from lots of experience. Please don’t blame the tools being used. When diagnosing issues like this, look closely at the components being used first.
Also one tool to assist you in this regard to gain a feel of brass internal size and all the way down the neck would be the Forster inside neck tension gauges. A very helpful tool and recommended for sure  https://www.brtshooterssupply.com.au/product/forster-neck-tension-gauge/

Troubleshooting Bullet Seating

 

On another subject: Die position within the reloading press here is Stuarts’ tip,

I like to illustrate and describe the correct setup position of the Forster Ultra die within the reloading press a little differently to that in the instructions sheet supplied by Forster Products. I like to call this a sort of “double check”. Because This is a visual thing. I will use a ‘Sharpie’ pen to draw a temporary line on the sliding sleeve of these dies. Just above the engraved word FORSTER. You can see this is the pictures below. Then I insert the die into the press (any reloading press) and adjust the die height so that when the ram with a shellholder, or as in these pictures, the Forster Coax press  shellplate pushes the die cartridge sleeve up into the die at full extension then this ‘sharpie line’ line is just covered, yet the full amount of the engraved word FORSTER is still visible. The result is the sleeve pushes into the die body about 1/2 of the total travel and that is the correct position to have it.
If it travels into the body too far there is high risk that the bullet seating stem up in the die can move down out of its support area and the thin end could flare out with high bullet seating pressure. On the other hand if not wound down far enough there will be trouble gaining seating stem adjustment. So once this is achieved that is the lock up position and leave your lock rings set at that so you can repeat settings in future reloading sessions.
