i went to one of my friend's place and he showed me a ross in .280.
he told me it was pretty hard to find some ammo.
looks like a civilian model,can somebody tell me more about it?
 
The Ross Rifle Company made at least three models in 280 and in several grades. There was the 1907 E model and 1907 R model and the M-10 model also. They came with different stock grades and sights, some M-10`s were set up for long range shooting. The 280 was supposed to be the be all to end all of cartridges but didn`t work worth a hoot on thick/heavy skinned animals in Africa. RCBS sold 280 Ross dies back in the 70`s which is when I had mine but like a fool I sold it. I can not remember who made the brass but it might have been from the UK. Price will depend on which model/grade but a collector will pay big bucks for the right Ross.
Hope this helps some, I will dig out some of my old 280 data.

.280 Ross

I run .300 H+H brass through my .280 Ross RCBS sizer die (right over the belt) and trim to length. Have used regular .284 140-160 gr. bullets. Used a medium 7m/m Rem Mag load, I think 59gr. IMR4831. Cant say how they grouped, but did fire and eject just fine. As with working up any load, use due caution.

The Ross uses a .288 bullet, standard .284s might work. There has been .280 brass made recently.
 
Bertram in Australia makes brass, but it is much easier and cheaper to reform .300 H&H.

All original .280 rounds in my collection have bullets of .283-.284" diameter. The only .288" bullet I have found is on a specimen of the experimental .28 Ross cartridge for which only a few rifles were ever made.

Try a .284" bullet and kick it in the rear end with a hot enough powder and it should obturate. Original loads used Cordite in some, and it was HOT stuff: 57% nitroglycerine!
 
Neat cartridge that was WAY ahead of it's time. It has the same taper as a .303 british case, but has a rimless type extractor groove that maintains the case' taper lines. At the time, it was probably the first "real" smokless magnum round.

Not sure I agree about poor performance on thick skinned game. Bear in mind that we have FAR more bullet designs to choose from today than the one round-nosed cupro-nickel FMJ bullet the .280 Ross was constructed with at the turn of the century.

.280 Ross rifles were rather popular with target shooters at one point, as well. Even gave the .300 H&H a good run for its money back in the day.
 
I just checked the diameter of some Kynock ammo I have and the bullet is 285 and then I checked some orginal Ross ammo with Ross patent 140 bullet and they measured 285. If I get a chance I will slug the barrels on my sporters and see what the actual diameter of the bore is. I have shoot my rifles with 284 bullets and they worked okay but have never went right at working up loads for any of mine

I had same findings as WR1894. Also havent had time to test lods for accuracy. I ran .300 H+H brass through my RCBS dies and trimmed to length. Dont see why .300 WinMag brass wouldnt work as only comes out a tad short after sizing.

I checked the barrels on my 3 280 Rosses today
SN 13976 a late M10 sporter bore .280 grooves .287
SN 7965 a early M10 sporter bore .280 grooves .287
SN 3005 a Model 07 Scotish Deer Stalker (this is the action they made the 280 match rifles on) bore .280 and grooves .286 by my measurements. All barrels were 4 groove rifling
In my mind this was typical of the era and .284 bullets would be fine, you take a 303 British the bore should be 303 and the grooves usally run up to 315 to 318 and they used .311 or .312 bullets. The 7 X 57 is the same with grooves around .285 or.287.
In my opinion the Rosses were loaded with .284 or .285 bullets all along and some were along the line somebody wrote they used .288 bullets which in my guns are over size.

I never tried to use a 300 case in my 280. I heard they worked but I always wondered about extraction. The Ross is semi rimmed. The 300 is rimless. Could this be a problem?

It has been a long time since I have bought any Ross rifles and I may need to sale a couple. I can't seem to get the pictures to come though so I wll give a breif description and maybe somebody can give me a ball park price
The first is a Model 10 in 280, bore is good and has good wood with a recoil pad. The barrel has a new front sight and the rear sight is the Porter peep sight.
The second rifle is a full military model 10 with a good barrel and is good rifle the date on the stock is 1916
Thanks
