RCBS Matchmaster FL Bushing Set 300 Win Two Die Set; Seating depth...

This has the primer punch and full-length sizing die and the Matchmaster Micrometer Die. These are the only two dies I need to reload for the 300 Win Mag? Is it best to seat the bullets to the factory overall length or should I try the old way and seat the bullets for an overall length where the bullet is very near the throat of the barrel? The rifle is a Weatherby 300 Vanguard 2 S. Thanks for the info.

FYI.. Your going to need the proper sized bushings as well. I have the matchmaster sets in 223 and 308. It's all I use outside standard reloading equipment.

I just used three different calipers finding that both once fired and factory loaded rounds measured about .34 outside diameter. I will check the book for the necessary subtractions and order the sized bushings. I think there are steel bushing and another type? Which is preferred?

Hope this helps.

Sizing dies require the purchase of appropriate neck bushings for the caliber you are loading. To determine the proper neck bushing size, measure the outside neck diameter of a loaded cartridge and subtract .002” to .003” to allow for a small amount of brass spring back. I think I have 5 or 6 different bushings for my 308 but my brass is mixed. Have yet to play around with it all that much as I sized it all previously before my bushings showed up.
