The next little thing

Thought about it, but my warped pilot's mind has a hard time imagining a stiff enough skeleton being lighter than a foam / balsa core monocoque.

He was probably thinking about the old Kifaru Rambling Rifle.

Why not get in touch with MPI? Their Microlight weighs something like 16oz - so 1 pound. Your action is 1.25 pounds, so that puts you at 2.25 pounds plus barrel - assuming the 2 piece stock would weigh the same, when it really should weigh less. That gives you 1.25 - 1.5 pounds for the barrel.
 
Here I found a picture of it, not as big as you want ,

maybe the Myra though
 
Honestly if it was physically possible to launch a 400gr .224" I'm pretty confident there would be no difference in lethality between it and a 400gr .458. :)

That then becomes a bullet design argument. Not speed vs mass and frontal area. Good topics for another thread.

I've actually been considering the 250 savage and 25/45 sharps for a single shot coyote and crow gun over the 223. However I'm not concerned with weight. I look forward to your results
 
The Myra / Copperhead is too slow for my application, would make a nice ultralight deer rifle for close ranges, I need it to reach 300+ if required.

What is the capacity of the X50 case?

Here is a Chuck Hawkes article on .22 centerfires for medium game... as always, long on opinion, but he discusses the European options, including the 5.6X50 Magnum.

The goats and sheep you're after how much to they weigh on average? Also do you shoot to anchor them or lung shoot them and hope they don't fall off the mountain? I've never hunted in the mountains and the only sheep I've shot was domestic. I've never seen an animal die as fast as that sheep. I shot it at 350 yards with a 25/06. Hit low thru both shoulders. It didn't even twitch
 
A mature billy on the north coast is 300lbs live weight, for a client I ask them to anchor with a shoulder shot. I'm not concerned about waiting for shots and taking the heart / lung as I get a lot of time over the season, out simply for the lightest possible rifle of range. It'll come with limitations and I'll treat it like one does archery, use it within its limits and don't push it. :)

Actually haven't shot one of fill and see yet, but from Mike Bellm's (TC wildcatter) page his improved version holds,

Note: This case holds nearly 37 gr. of ball powder, and about 34 gr. of stick powder, compressed.
 
I'm of the opinion the game never notices the bullet's three sheets of paper in thickness bigger aside. ;)

Honestly never thought I'd be adopting cartridge minimalism but really want the lightest possible rifle that can reach.

Angus, somewhere around here I have a picture of a lovely ram that my wife took with her 25-222 Magnum more than forty years ago.

I had PO Ackley barrel up the rifle on a Rem 600 action. I forget what it weighed with a 4X Redfield 3/4 inch rimfire scope, but it was very light, considerably less than my Husqvarna Featherweight 270. The barrel was his number 00 lightweight contour, and the rifle was crazy accurate. Twenty two inches long, it got 87 gr bullets over 3000 fps and 100s past 2800. Those were real velocities over my old Oehler Model 33.

I also have a few rimmed 25-222 brass around here that Bevan King imported from Australia years ago. That I could send you the dimensions of if you wish. Just a couple more to think about that could be easily set up on that action, and make that weight for sure.

My 25-303 Imp rifle was on a No4 Mk 1 and would get 100 gr bullets way past 3100 fps, but that rim would be a bit of a mouthful for the Hagn mini action.

Ted, I have chatted with precisely one person who had PO Ackley barrel them a rifle; you. :) Way too neat and glad to see similar thinking sprouts in similar applications regardless of time. Your .25-222 Magnum was claimed by Kimber and called the .257 Kimber, very heavily considered for my project. I ended up buying a Gaillard .224" 1-8 the other day and having it sent to Martin to turn down to AR pencil barrel dimensions, and will likely stick with the straight 5.6x50 Magnum or a standard long neck improved version of it for now. The goal is to take the biggest mountain goat my area can produce with it on day, and carry it an awful lot until then hence the 3 1/2lb hope. I will make Whitehorse again soon and would enjoy buying you a coffee.

I was looking the CIP pressure numbers and the R version is held to a significantly lower pressure. This is interesting because it isn't exactly an old design. Is it due to weakness in the brass or in deference to potentially weaker actions?

That's bigger than I was expecting actually. Having never seen one in person I just assumed they were closer to the size of a regular goat and not the size of a mature white tail buck
 
Some are even heavier than that. I well remember walking up to the first billy I shot, and was amazed at how big it was. Certainly glad Garry was my hunting partner that day. It was all we could do to pack all the meat, head, and hide off the mountain in one trip. Siwashed in a patch of juniper in the rocks that night, then discovered we were both barely able to hike on the level the next day. It was no wonder we never made it all the way down through the rocks that day.

Not sure what the exact weight was, but we both agreed they were heavier than any moose quarters we had ever packed. Crazy!

Those were the days my friend. We thought they'd never end.... but here we both are, 43 years older.

I reckon that for my own use, I'd go with a Browning Low Wall action from the ones made between 1985 & 2001. I would also use a smattering of titanium bits and carbon fiber to make it quite feathery. The chambering would be .25-35 Winchester with a 22 in. tube.

I just gotta have a hammer or cocking piece on my stalking rifles.;)

The Hagn built unit should turn out nicely though.:)

Indeed both the R and non-rimmed brass is identical in capacity and strength, they download the R for weaker actions.
