Was about to pull the trigger on a Dillon 300 BLK trim die ($176) when I saw they wanted another $17.49 to ship it.  I started looking around for a cheaper one, and found a Whidden Gunworks 300 BLK trim die for $52.99, which looks like it will work with the Dillon trimmer.  The description is kind of confusing, and I was wondering if any of you could recommend it.

ETA: I'll be using a Dillon 1200 trimmer, on brass that I've already cut most of the excess off of.  I know they say it will burn up the motor using the 1200 to trim them all the way down.

Whidden 300 BLK Trim Die

Sounds like you are looking at a Dillon carbide die. They no doubt have non carbide version too. Look at Grafs for cheaper shipping on Dillon stuff.

I think I have the Whidden. Dont recall. I bought it way before Dillon came out with one. CH4D is also a great resource for Dillon trim die. No doubt 300BLk is in stock. I ordered a non-in stock trim die last week (7.5 french).. ETA 9 months!!! sigh. Good die though. I have many of theirs (30-30, x54, x39, 8mm mauser, swiss).

If you are not aware, Dillon refused to sell 300BLK die because they dont want people trimming 223 brass down to 300 using the 1200. When they released bigger trimmer, so came the new die.

Myself I'll stay with the CH4D trim die , as IIRC the trim dies Brads warehouse was selling were from Whidden and had one break in two , and have seen a couple postings over the years of it happening to others, I'm not ham fisted with tools as I make my living working on equipment and machines

ETA : my first trimmer was a used rt1200 it gave me north of 33,000 each of .223 trimmed and resized and 300BLK formed and trimmed from full sized .223 cases before a buddy smoked it forming 300BLK

Yeah, I'm hoping it will work ok since I'll be cutting most of it off before resizing/trimming.  Shouldn't be cutting off but a small amount with the trimmer.

Thanks

You will be fine unless you are using it for commercial production. I used 1200 same way till I got
the bigger one. Good luck!
