Reloading 300 Blk in a Progressive Press

[MMH]

I generally load rifle using a single stage press. Most of my rifle is for precision loads (shoot a lot of PRS). W a single stage press I decap, tumble, FL size, tumble to remove lube, check case length, seat primer, drop powder & then seat bullet

300 BLK is not what I would consider a precision round. I want decent ammo but am not trying to get to 0.5 moa w/ it. What would be the sequence for loading in a progressive press?

I load mine on a Dillon 550, I tumble the brass, spray lube a batch and let them flash off, then run them through the press loading them all the way. After they have been loaded I wipe them down and give them a tumble in corn cob for about 15 mins to knock the last of the lube off. Yes running loaded ammo in the tumbler. As I am using CCI military primers I don't worry too much about them going off.

300blk can absolutely be a very precise round with a quality barrel and good loaded ammo..

I load all my 300blk on a 650..

H110 meters great from the dillon powder measure for supers and is stupid accurate out to 500M from my 10.5" Rainier Ultramatch SBR.

I do 300blk in a 2 toolhead setup like my other rifle calibers. I use a loading toolhead to size, trim and mandrel the brass and process a lot to fill bins.

I then load in a dedicated loading toolhead with a decapping die in 1 to confirm nothing in the flash hole like media.. then seat primer and drop powder, Forster Ultra Micrometer seating die



Here 7 five shot groups @ 100 with my 125 TMK load all loaded on my 650
