Huh....Not sure I follow what your saying...Well sure if it won't feed then it is a feeding problem. [/quote]
It is simple rifle build terminology to clarify in precise terms what may or may not be required.
The choice of the word problem is simply a poor choice of words and inaccurately describes what the build may entail. The word problem implies that you may never be able to get the feed to work properly.
Anyways...I am pretty sure you still don't get it but no worries mate.

Thanks to some of the guys here for advice, I will tell my brother to make his a 280 ackley.
Rechambering a factory barrel that isn�t getting the velocity one is looking for is throwing good money at bad. The barrel is likely still going to be slow, but now it will be slow with a few hundred extra dollars sunk into set back/rechambering and new dies. What I�m trying to not so eloquently say is that rechambering won�t fix the slow velocity issue if the barrel has loose bore dimensions. Also, I�m not sure what being a �reloading chicken� is, but a 280 AI isn�t going to change things. If that means your brother backs down when pressure signs are encountered on the brass, he is a smart man, as pressure signs don�t often occur until over 70,000 psi. Have him load some 120 ttsxs at 3150 fps in the factory barrel, and he�ll not want for a 280 AI any longer. Also the idea that a 280 AI is lighter than a 7 mag is just wrong thinking. Same stock, same barrel, same action...the magnum will be slightly lighter because the chamber removes a little more steel. Kimber 84L changes that The problem there being the throat length to magazine length on the Kimber 280 AI. Long throat, not so long mag box. Prairie goat, my brother has a krieger chomoly #2 finished at 22" ready to be reamed, he was debating on either 280 or improved. what's to hurt by going improve, still be able to shoot the old 280 and look cool. It's his gun, so he can build it whatever he likes. As for me, doesn't matter if I am shooting a 7 mag, 308 or 270, I limit all my shots to 300 yards so deer won't know the difference and so do I. You originally mentioned a rechamber, not a rebarrel, hence my comments regarding rechambering. If going with a new barrel, a 280 AI is a fine choice. In fact it's just as good as a 270 or 30-06. P.S. I would seriously consider a SS barrel for a backpack rifle.

I bought that one a few years ago. I took a decent buck with it last year shooting 162 amaxes at 3040 fps. Shot was about 400 yards and it worked well. I had to bed the lug and sand the channel a bit but now it's a sub moa gun and handles like a dream. Bb

I have had three "improved" 280's, two AI and one RCBS. I have also shot a 280 a lot. My 280 with a longer throat, OAL 3.45, is about 30-35 fps behind the "improved" cases at equal pressures. In a hunting rifle, I would use a 22-23" barrel.
The reason the improved cases are more difficult to get to feed as slickly as a standard is because of the reduced body taper. The shoulder angle has nothing to do with that other than most "improveds" have both.
Also the idea that a 280 AI is lighter than a 7 mag is just wrong thinking. Same stock, same barrel, same action...the magnum will be slightly lighter because the chamber removes a little more steel.
I would get the standard built but have the throat extended. Cases and dies are cheaper. Or just get a 270 or a 7RM.
I've never seen a factory barrel chambered for magnum that didn't haven't a heavier barrel contour (longer shank) than the same rifle chambered for non-magnum rounds. Why do the factories do that ?

Prairie goat he is having it ceracoted and krieger doesn't make skinny SS barrels for his lightweight project.

They ain't gonna cerakote the bore. That's where you need the stainless.

Exactly. Plenty of other manufacturers make skinny barrels in SS. If he's dead set on a Krieger tube, it's no big deal to order one in a heavier contour from someplace like bugholes.net and have a smith turn it down to his preferred contour before screwing everything together.

59 gr of RL-19, 140 NBT or 140 Barnes TSX, 3020 FPS.
Always liked that rig. For conversation, 57.3 gr. of RL-19 w/ 140 Accubonds averaged 2,954 FPS in my 22" M70 and 60.5 of RL-19 w/ 129 LRX averaged 3,084. I like that powder in my 270, but it didn't show me much speedwise in my 260.

When I go to 150 or heavier in either the 270 or 280, then I prefer RL-22. MM

These Kimber 7mm WSM's and 270 WSM's weigh less than a M70 Featherweight rifle in 280 and are better guns.
I got the 270 WSM Kimber first as many said the 7mm WSM would not make it. Then I had to get a 7mm WSM anyway!
I have not had time to finish the 7mm WSM but it's shooting 168's well. I want to shoot 140's.
The 270 WSM Kimber has been outstanding from the start. I took a very large buck with it. It's shot the 150 gr SST into a 1/2" group at 200 yds the other day and the best part was that it had remained sighted in. Right on at 200 yds!

I and many others here in the pacific west have hunted here with blued guns and it doesn't seem to affect us if you take care of your guns and everyone should. Piece of tape over the muzzle and the bore is safe. Matter of fact my brothers gun he is re barreling right now has been to Alaska, Washington, Oregon, California and British Columbia and has shown no rusting or pitting, only a worn out barrel from all the game he shot. Prairie goat, he choosed krieger because he has had accuracy issues with the light buttoned rifle barrels. So he swears by the light cut rifled barrels,

First of all a long action model 70 can be made to just as light or a little over a 8400 wsm with a edge stock, light barrel and bottom metal with talley lw rings. Still a beefier and better action vs the cylindrical 8400 wsm action and no Russian roulette to play.

Built mine on a mouser action and the claw extractor required some minor work to make it feed well. A push feed would be no "problem" I mean extra work.  Shod

You should be able to get 3000+ fps out of a 22" barrel with 140 grainers no problem. I get 3120 with my favorite 140 grain load with a 23" barrel without pushing it. There is probably a little more there but I have been happy with that load. Today I chronographed loads in my 22" barrelled A1 using 160gn Accubonds and 60gn of Rel 22 which is a half grain under the Nosler book Max load. It developed 2940fps which I thought rather useful in my Winchester Featherweight. John
When truth is ignored, it does not change an untruth from remaining a lie.

Tough to make a RCH worth much, particularly in this case.
