You can find fishing weights that are about the right size and they are soft lead. That makes it easier to drive through the barrel.

Very likely you would have to swap out several of the weights so unless you can buy those too you might want to rethink it.

A BHN of 15 is slightly harder than the wheel weights and range scrap I have been getting by a point or three.

I do want to say the one case I know of was a Ballistic Advantage barrel, not 100% on that but pretty sure. I believe it came down to how the chamber was cut and there was nothing that could be done about it.

I've heard of that odd leading issue and I thought it was related to the barrel. Mine does not do it. On the off chance who made that barrel?

The $2.99 option https://www.midwayusa.com/product/100340833/utg-accurizing-wedge-ar-15 "Improves accuracy" :^) put two of them in! I hate those, when they get old they can crumble and get into the trigger. I've had a couple kicking around for something like a decade, I just checked them ...

I use a accushim

I use NOE's version of the M die and all you have to do is let the second step enter the case mouth just a bit. Unless you are seating cast bullets you really don't need the M die.

You don't say what headstamp the brass is. There is good and bad brass for conversion.
