Match Master seating dies Question

[stormthelab20]

I reload for 300 Win, and use a set of Match Master dies. I'm having a 300 PRC chambered as we speak. Would there be any reason I couldn't use this seating die with both cartridges and just get a PRC F/L bushing die? Of course, RCBS says they are caliber-specific.

Also any suggestions outside of RCBS MM line that you guys suggest for 300 PRC F/L bushing die? RCBS only sells the MM dies as a pair..

Just run it through the die and see if it works - I suspect it will. I used their 22 Creed MM seater for my 22-250 AI without any issues at all. I would think the same for 300 PRC and 300 WM.

For a FL bushing die, I tend to use Redding for the most part.

Sounds like a good idea, thank you.

How well do you like the matchmaster dies?

 

[stormthelab20]

I like them. No issues and my load performance is where it should be. Being able to load the seating die from the top is really nice.

Right on. Does the collar work pretty good at keeping the bullet straight?

I love the matchmaster dies with the bullet window to drop it in. I have quite a few and theyre my favorite. I hate having to hold a bullet in the case mouth as I pull the press arm down. Not sure why more companies dont go this direction.

I believe the differences in the dies are the black floating piece that the case comes up into to seat the bullet.

Those are marked cartridge specific. I havent measured one to verify but I believe that they are sized for that specific cartridge to match the shoulder. They center the case when it comes up and the bullet is centered in the top. I wish they did sell just those pieces though. I could save some money swapping those out.

100% they sell the seating dies separately.

As far as FL sizing dies. I went with Forster because theyre supposedly one of the few that come down to size the base of the PRC cases. I have the regular FL sizing die, no bushing, and thats the most accurate and consistent ammo I have ever made. Not sure if its the proof barrel or the die but im talking about groups that would make a
223 jealous. I might try another Forster FL sizing die in a different cartridge to see if I have the same results. I dont even mandrel my 300prc ammo or do anything "extra" with it.

Great info, thank you.

Nice. I’m getting back into reloading and I think I will be going with the matchmaster set. For the money they seem to be great.
