My 30-284 ai reamer set from Manson is up for sale. Includes finish removable pilot reamer, 0.2995 finish pilot, solid pilot resizer reamer, and 284win ack go gauge.

It's only cut 1 barrel and die, in great shape. The resizer reamer has a ding in 1 flute from the smith fumbling it, doesn't affect the finish at all, see picture for location.

The barrel I have chambered with it is super accurate. The cartridge is awesome, but want to move back to something that is less expensive and doesn't require fire forming.

It shoots 185 jugs extremely well, and is throated just about perfectly for them. The boat tail junction sits just above the donut area and jumps 0.020-0.040 depending on where you seat.

I recently sent the reamers to Manson to have them measured due to some brass sizing issues. It ended up being that my sizing die was cut a little oversized and likely my chamber too. Ray at Manson reamers measured all the dimensions of my reamers and they were all in spec, except the body of the resizer was a little bit by 0.0005 or so, so they fixed that. Everything is now spot on. I can provide the measurements Ray gave me if wanted.

See attached prints and reamer pics.

Reamer set w headspace gauge is $400 shipped in continental US, venmo, PayPal FF, or check or money order


Also, If interested, I also have a sizing die, seating die, cortina precision expander die body, some brass (about 4 boxes Peterson and 1 box Lapua in various stages of life), and mullerworks #3 24" Tikka barrel w ~600 rounds on it that I'd sell. I think I'd like $450-500 for these items, but we'd have to discuss the specifics if you're interested.

I'll sell all of it to you for $800 shipped.

Very cool, what degree shoulder are you going with?

I've got a special reamer coming from jgs in September and I can't hardly wait
Probably just a plain Jane 35 Shoulder. We are not going to build anymore AI Cartridges. Too much extra cost for everything. Here is a copy of our 6.5x284 that we made from JGS a few years ago. Probably going to stay close to SAAMI on the 1/4 Bore with maybe a tight neck and we can throat longer if we want (we have Throater cutters).
If going with a 25x284 we already have the Brass, Dies with Bushings, Barrels and just need a Reamer.
Let us know when you get your Reamer and if you want to sell after you chamber your barrel or make a deal to let us use your Reamer.
At this point we have more Rifles/Cartridges for anything that we could hunt in North America and have (10) new PRS/"F" Class/ ELR Rifles so building a 1/4 bore is more of a "Want then Need". When making a Target rifle the COSTs are great for the Barrel/Action/Stock/Chassis/Trigger/Scope Mount/Scope/Rests/Custom Reamers/Custom Dies then adding into the mix Bullets/Primers/Powders/Brass. Could be getting into $12K+++ per rifle Build.

We always wanted another 1/4 Bore since having a 25 WSM.
Might just go with a SA in a Lite MPA Chassis in a 25 Souper.

If we can help you out with anything let us know!

Thanks
Len & Jill
