All good advice that I can add little too.
Things I have found out, jam or crush fit will not always guarantee a nice fire formed case. I have come to the point I anneal and end up with well formed cases, with a crush fit. Jam definitely raises pressure and insures growth will keep head separation to a minimum.
Fire forming loads 9 times out of 10 will give some really decent groups. I don’t look at them as a waste of components.
I use virgin brass and have very few issues. I still anneal these.
Imho this is a great cartridge that is looked over by many.
