Hey guys, I'm having a 7/300 PRC built and trying to see what people are doing for a seating die. I'm probably going with a SAC sizing die but their seating die won't work with my co-ax press. Thanks.
I have several necked down wild cats and just use the standard cartridge size for the seating die. I end up with very little runout and excellent groups. So in your case, whatever 300 PRC seating die that suites your fancy.
I have looked at SAC die for an arbor press but was trying to avoid buying another press and their $400+ dollar die.
I was looking at custom Redding dies but they're 20 weeks out. The necking down isn't an issues I'll be basically doing what @Huntaddict said for sizing, just trying to find the best option for bullet seating.
You can also buy a 7 mm seating stem for some seating dies, like Hornady and Redding competition line of dies. Getting an K&M arbor press and a LE Wilson seating die will probably be more
Like $220 way cheaper than SAC
