Like many others I was intrigued when nosler released their 26 nosler but thought their case design was ridiculous. I thought it was way overbore for a 6.5 along with a short neck but could be tweaked to make a fine 7mm. I bought a box of 26 nosler brass and started playing. First things first, get rid of the short neck and bump the body back to get the neck length similar to the 7 saum. I played with the design until I found one I liked then took the case to my smith to tweak a little more. He noted a few more changes and drew up the reamer design and sent it to Dave at PTG. Six weeks later we were in business. I gathered up the rest of my parts and we chambered it up. Currently the rifle has 140 rounds through her and seems very forgiving in regards to seating depth and powder charge. All seating depths and powder charges land in 5/8" groups or less. We've shot H1000, Retumbo, and Ramshot Magnum and all shoot really well. Current velocity with 180 JLK's is 3234 with a mild load of Retumbo, I'll play a little more but 3300 is not out of the realm.

Brass prep is fairly simple but requires a little neck turning but is so easy even my buddy can do it!! Haha

Specs of the rifle:
Stiller Tac 300 action I had laying around
25.5" #4 Brux spiral fluted 1in 9 twist with custom side discharge break
McMillian gamescout mold in color stock
BDL bottom metal w wyatts window box
Timney trigger w long sear and narrow shoe
Talley LW aluminum rings w 20 Moa machined in them
Leupold VX 6 3-18x44 with TMOA reticle
Current weight as show is 9lbs flat

This chambering was named the 28 Yukon because I have a Moose, Grizzly, and Caribou hunt booked for next year in the Yukon. All smith work was done by Trevor at Cloud Peak Gunworks. He built one for my buddy as well that is heading to the Yukon with me and he is having very similar results. Soon I will be stretching her legs out to a mile.

7 saum, 7mm Rem Mag, 28 Yukon. I really hate that you can't upload multiple pics from an iPad!!

Thanks, so are you running higher pressure to beat the 7rum by 100fps?

Dunno what the 7 RUM runs for pressure. What I do know is quick load says my load is under 65k and there are zero obvious signs of pressure on my cases. Case life is good with the 80.5 loads with 5 firings on my cases and still hold a primer well. Primers are still round with very little case stretch, easy extraction, and no smileys.

I agree, the neck length on the Nosler could have been longer. My preference is a neck .010 longer than diameter. I've been working on something between a WSM and Nosler and may yet tweek the neck length to be a bit longer.

How much did you bump it down?

Can you do a pic next to an unmodified 26/28-Nosler case?

I won't get into any of the specs of the reamer as it is proprietary to Cloud Peak Gunworks but I will say we bumped it back significantly. Here is a photo of an un-modified Nosler case and the 28 Yukon.

Umm yeah, proprietary. Your gonna make a million.

Sorry for the sarcasm, nothing personal intended its just that I've lived through so many "proprietaries" including being sued for patent infringement by a contractor who patented my work under his name. He lost. I spent money on lawyers but never got anything back.

IMO the best way to promote your design is to release it for use at large. In analyzing designs and adoption I find that less is more. Less restrictions more adoption.

Not trying to make millions but why not allow the smith that worked with me to design it to something we thought would work better make a few bucks off of it if others choose to go that route? If someone else wants to design the same reamer and have it built under another name so be it that's perfectly fine it's a free country. Hell there will probably be way better designs than this one but for what I wanted this seems to fit the bill just right. Totally understand the sarcasm and no offense taken. There are several smiths that hold their reamer designs tight on their niche chamberings, at least for a while.

Yup. No problem with that. Never seen a smith make anything that way. Maybe just pay for the reamer unless you paid for it. Oh and his fees for doing the chambering. Um, yes. That is what they do for a living...

If it's coming from Trevor it's good to go! How was the case preparation? 180 grain bullet at 3300 fps sounds promising!
