    I'm having a 300NM built and am starting to collect reloading supplies. Other than Forster, does anyone else make dies for this caliber - specifically a neck size only? I heard Redding does but they aren't listed on their site and I can't find them anywhere.
     
    Frank is right the WTc die is a piece of art, also remember to buy several neck/shoulder inserts so you can adjust neck tension accordingly.
    And you can get a new body insert and neck/shoulder pieces to use it for several similar calibers if the price is hard to swallow. With the supplied headspace shims this works quite well, as long as you keep a record.
    Just be aware of the need of 1 1/4- 12 threads so it will Only work with some presses.
    This along with a custom inline seater is the best you can get IMO.

    Ideally you want to use 3 pieces of new brass fired 2 or more times and Only neck sized from the previous firings for any of them.

    If you need 7/8-14 threads Neil Jones also makes excellent sizing and seating dies in several variations.
    I do prefer my Wtc sizer though.

    Other options is Triebel guntools in Germany, they are of very good quality and will make you custom dies in both thread pitch sizes. The gem of these are the BR seater with seating stems made to match each type of bullet you use.
    Have a set delivered with a chamber reamer from them and the results are excellent.

    Last Whidden Gunworks will make you a custom set from reamer prints if desired.

    Gonna be a little pricey but I would send a fired case from virgin brass and have WTC (Warner Tool Company) make the die for me. They will match the die to your chamber and give you the neck size bushings that you want/need. I did a write up on they're dies a while back.

    Awesome, thanks Frank. The rifle is still at GAP being built (Bartlein #11, 10 twist!). I'm just collecting reloading components right now but as soon as it's finished I'll give Warner a call.
