7/300 PRC seating die

[RevXP_09]

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.

Ok thanks, runout was my concern, I'll pick up a standard 300prc die and see how it goes.

If you can get a 300 PRC in line die for an arbor press and buy the 7mm bullet seating stem, this has worked for me well.

I have had a 7/300 for 5 years.
Reading 300 PRC type S with a 310 bushing

Buying 300 PRC brass. you will likely need 3 bushings. 323. 317. 310.

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

No one has a 300 PRC Die? Anywhere?
That sucks - if I had another one, I would offer it to you

How does the SAC sizing die work with your press but not the seating die?

I love their seating die, which can be used for multiple cartridges as well... maybe offsetting the high cost?

Your gunsmith will make an in-line seating die for you, any caliber he chambers
he can make a seating and /or shoulder bump die for you.

The overall height of the SAC seating die with the micro adjuster is to tall for the co-ax press

Call RCBS. I think they have a set of three dies.
