I bought the Dillon trimmer to use on my rock chuker to help with making some 300 blk brass (I've been using the WFT, but after a 1000 rounds, I'm tired of that). From looking around online it seems as if a lot of people don't just like using the trim/size die by itself.  Do I need to use my regular size die before or after the Dillon trim/size die? I've also seen people mention the Lyman m die when using the Dillon trimmer.

Any advice on steps while using the Dillon trim/size die will be helpful!

I run the M-Die after the trim die , no need to run a sizing die before the trim die in fact Dillon will tell you not to as you want the trim die to have a good hold to keep the brass from spinning in the die.

ETA: I don't use my regular fl. sizing die at all

You don't mention what type of press you have.

ETA: I can't read properly.

On a single stage press I would just use the trim die and follow up with a M die to clean up the mouth.

Thanks guys! Sounds like a plan!

The Dillon trim die cannot expand the mouth, as it doesn't have an expander on it. That is why people use the Lyman M die afterwards to open up the mouth to get the proper neck tension on the case.
