Hello All,

I am putting together a tool head for my Dillon XL650 for realoding .45ACP.

I always use a Redding Carbide FL Resizing Die in my first station.

In my 4th station I typically use the Redding Competition Seater Die.  However, while putting together the list of items to buy, I came across Redding Bullet Seating Micrometer, which threads into a standard Redding Pro Series Seater Die 45 ACP.  The Competition Seating die is $102.99, while the Pro Series Seater and micrometer add on are only $71.98.

I plan to use standard 230gr FMJ RN bullets. Just trying to figure out if the extra money for the "competition" seating die is worth it.  I do have a Mr Bullet Feeder, I know the Competition Seating die  states that it helps to "align" the bullet, though I thought all seating die's basically did this.

In my 5th station, I typically just use the Lee Carbide Factory Crimp Die

Thanks!

the redding comp has a bushing sleeve that aligns the bullet BEFORE any pressure is put on it into the brass, so it is kept in better alignment during the entire seating process.

Whether that matters to you or your ammo I dont know.  I just use standard Dillon dies for seating pistol bullets.... as I only make practice ammo, and not shooting accuracy competitions.

For my rifle ammo, I always always always use the Redding Competition seaters.

For my 45 acp I use Redding comp resized/deprimer in 1st, DILLON powder charge In 2nd, Redding comp seater in 3rd, and Greatest die ever made Lee factory carbide crimp die in 4th. Can’t see ever changing this set up. Redding comp dies are the finest out there. Consistent and accurate. Takes some time getting set up, but after that it’s just pull the handle.  Cost is a little more but you get what you pay for.

I was thinking about getting just the micrometer stems, but couldn't find anywhere that listed thread pitch/diameter, so instead just got the competition seater.

They work absolutely great on my 750 and 9mm and .45 tool heads. I bought them because the tedious nature of trying to set to a certain OAL always bugged me. Now it's measure the first one, adjust, and you're good to go. I love them.

You need to leg work to cross reference the Redding Mircometer Seater Plugs
You down load their catalog look for the regular die sets and the parts across the listing shows seater plug #.
Then find the listing of the Bullet Seating Micrometers and look to see if there is one available.  Handgun ones would be Flat ones
