What's your favorite to use with an Arbor press? I've used the LE Wilson bullet seater on my 6X47 Rem and .223, and a Bald Eagle arbor press. However, I'm interested in the SAC inline seater die as it is kind of a universal seater. It's expensive, but not as much as buying Wilson inline seater for every cartridge I want to reload for.

I figure I can load long and do seating depth testing at the range. I've tried this with a Lee hand press and micrometer seating die, but it isn't as consistent as I'd like. I'm not bullet sorting BTO, so it could be that. It could be caused by the hand press as well, IDK for sure.

I just know packing my Arbor or Lee press in the range kit is easier than getting a press like the RCBS Summit to haul to the range. I'd have to build a base to clamp to a bench and carry C clamps. Then upgrade most of my seating dies as well.
 
If you do not get replys here on the SAC dies. Its fairly popular with prs shooters and the like. The Hide and accurateshooter might get you more first hand knowledge. I am getting one soon along with their sizing die. Everyome I have spoken to and have read posts from has been very happy with them but I do not have first hand experience for my own loads. They have really expanded the parent cases they cover from when they first started offering the dies.

I have been so far impressed with SAC products I have purchased. Them and 21st Century put out high quality/precision well thought out products IME.
 
SAC will not disappoint. I have switched to SAC standard dies for my PRS rifles. They are a great company that supports the shooting community. Don't think you can go wrong.
 
The SAC is not as universal as it could have been.
You end up needing a new $475 die for each diameter of cartridge. That could get really expensive.
I think the base could be modified to be universal, so that only one kit would be needed.
 
I never understood the appeal to a universal die. One thing I hate screwing with is dies and I look forward to being done with load development so I can set and forget my dies.

I have always used Wilson or ones that have been home made with a Wilson top. I recently bought a 7prc arbor seating dies from Whidden.

So I don't have anything specific to say about SAC dies…their stuff is normally quality and you pay for it. One thing about the PRS crowd, they are loyal to the companies that support their games…that's a great thing.

It says on their website:
The INFINITY APS Die (Arbor Press Series) is designed to be the ONLY bullet seating die you will ever need when reloading cartridges from 223 Remington to the 338 Lapua Magnum from an Arbor style press. The Infinity Bullet APS Seating Die comes complete with 6 different bullet seating stems and 2 cartridge centering sleeves to handle conventional and solid turned bullets from 20 to 338 caliber, simply select the appropriate Cartridge Base Insert and you're ready to create high quality ammunition. Outfitted with .001″ tactile clicks to precisely adjust your bullet seating depth.

What your saying is this isn't correct?
 
The SAC seaters work for a specific base diameter. If the cartridges are of similar base diameter and fit in the same action they will most likely work. A Miyotoyo micrometer adjustment is used for small seating changes. Larger changes are performed using a precision ball bearing to make a gross adjustment and then the mic. It's pretty slick.
For some background, I usually load 2-300 rounds at a time and am chasing throat erosion in some of those reloading sessions. So it isn't a set and forget forever process for the type of shooting I do.

I set and forget dies as well. However, having used a Wilson inline seater at the range with an Arbor press makes seating depth tests easy. Then I set my seating die on my press to match my inline seater.

The INFINITY APS DIE will come with the following Items
  • INFINITY APS DIE
  • One Cartridge Base of Customers Choice
  • Small 1-2 stems for 223 Centering sleeve
  • Model 1-4 Seating stems for standard cartridge centering sleeve
  • 223 Based cartridge centering sleeve
  • Standard cartridge centering sleeve for everything for 224 Valkyrie up to 338 Lapua Mag cartridges
  • Short / Medium / Long Pushers
Do the different bases (11 types for different case head diameters) work with the same die body?
If so, how much $ are the different bases, and how do you order them?
It seems to me that in order for this to be "the ONLY bullet seating die you will ever need when reloading cartridges from 223 Remington to the 338 Lapua Magnum", then you would need all bases for cartridge diameters 223R to 338LM.

Good find on the bases. I could not find that.
If I bought into this, I would modify a largest head cartridge base for 3 spring fingers to center ALL cartridges.
So just buying one base.
 
I have one but being as untrusting as I am I still back it of 5 thousands from my targeted depth, measure BTO, and adjust from there. The adjustments are pretty spot on however. Just gets rid of that little bit of doubt lurking in the back of my mind. It is a slick set-up and works very well.
