.280 Ross M1910

I shot my M10 .280 Sporter today. I know the "correct bullet" is the .287 diameter. However I obtained some Woodleigh 160 gr. and my rifle didn't like them at all. Groups running around six inches. The 150 gr Nosler BT, 160 gr Speers and 154 gr Hornady IB will all group under 2 " with the iron sights. I use Win 300 H&H cases, didn't have to turn the belts off. Just form and trim.
It's a lovely rifle.
Incidentally mine has the Porter peep which is a pleasure to shoot with.
Many thanks to smellie and others here for sharing their knowledge on the Ross.

Can you elaborate on your re-loading? What size bullets do you generally use? And to continue harassing you.. where do you buy your brass?

If it weren't for this forum I'd have no idea what this gun was all about, so thanks again.

I made mine up from WIN 300 H&H brass. I was fortunate to get a sizer die with the gun. So I could just pull the decapping rod and size the 300 brass. Then I trimmed to length and sized again with the decap/expander in place. The trim to length info was a bit of a puzzle as Nonte's book lists the case length as 2.640" and Donnelly's book lists it as 2.580".
I used 2.640 as a rough trim length and the cases would chamber, however they were touching the leade and crimping the case mouth. After some further research I located a Winchester cartridge drawing which gives a case length of 2.610. This works well in my rifle and permits a .287 bullet to easily enter a fired case. I trim again at 2.620 ".
I used Nosler 140 gr bullets to fireform and even these loads averaged about 2. 5 inches. I've lost no cases in the forming process.
I ordered some Woodleigh .287 160 gr from Tradex and they grouped very poorly in my rifle. They also produced much higher velocities for less powder than a .284 160 Speer, took about 3 gr more to obtain the same velocity with the .284 bullets.
P.O. Ackley's book will provide some load data, as will Nonte's book and Donnelly's. Also Cartridges of the World.(Ackley's numbers are very close according to my chrono.)
My rifle like's .284 bullets in Nosler 150 BT, Hornady 154 gr IB and Speer 160 gr SP. It will regularly group these under 2 inches at 100 yards. (No scope) This support's smellie's information regarding period ammo with .284 bullets.
Jim Foral's Gun Digest article and Ross Seyfried's artricle are both good sources
of shooting info.
The Ross Rifle book is also and excellent book.
 
Lots of detailed information!! Thank you very much.

I'll admit, I've never reloaded ammo before and .280 ross sounds like performing heart surgery with a blindfold on.

I like a good challenge.

I suppose I'll call a few suppliers and see how many ".280 ross, what's that" replies I get.

Thanks
 
When a cartridge fires, the primer gets used up, the powder burns, the slug is blown away and the case expands to fill the chamber, then releases just a little so you can get it out.

In reloading, all you are doing is skooshing the casing down to its original size, putting in a new cap, dumping in a charge of powder and seating a fresh slug. The case has to be lubricated so it doesn't stick in the skooshing die.

Rocket science it ain't, friend: even I can do it.

YOU can do it, too! Your trepidation just means that you will have a much better chance of doing it RIGHT once you get up the nerve. The guys to be afraid of are the ones who already know everything.

Good luck!

Call back if you want help.

Alright.

I've plundered the search function. I've read multiple different forums. Here's what I think I will need so far.

winchester H+H 300 brass: A lot of consensus on the use of this case.

.284 bullets 140-160gr: Not a lot of consensus - a lot of talk of .287, maybe from worn old bores? Different weights mentioned as well

Custom or antique resizing and seating dies: some debate as to the accuracy of some of these dies. I read about RCBS dies, and Neil Jones custom dies. Pretty expensive stuff.
I don't have any dies with the rifle - do you think it would be worth my time and hard earned money to fire a round and send the case away?
I checked the EE and there certainly aren't any for sale :)

i to am in the process of reloading for my 280 ross,could not get brass in canada for the 280.Got some 300 H&H magnum brass from prophit river.ellwood epps as 300 H&H brass as well.Ordered dies from the us, no problem there but they wont ship the brass.Formed one peice of brass so far ,waiting on a case trimer to trim it to length then im ready to load.Going to use .284 bullets and see what the resultes are. Just about there now was going to sell the rifle at one point as it was getting quite fustrateing trying to find all nessacery items to reload ammo for it,and also not cheap i might add.300 H&H brass is close to 100 dollars for 25 count box,hope its worth it ha ha
 
"H&H brass is close to 100 dollars for 25 count box,hope its worth it ha ha "

Yeah, but did you see the price of the 280 brass? o_O

I figure if I can keep it under 10 bucks a round I might be able to afford to shoot more than once a year. Maybe on my birthday? lol
 
i wanted to have mine ready for the moose hunt this fall might be ready if i have to make a secound trip wont be takeing it this weekend though .Reloading should be as cheap as any other once you purchase the dies and brass,got my dies from huntintings in the us i think it cost me 117 shipping and all so it wasent to bad .
 
You should be able to make it out of .300 Winchster Mag. It's a little short but it will lengthen when you resize it; there is a lot of taper in that Ross casing which is NOT in the Winmag.

Hope this helps.

Not in the same class, but I had a 1910 military ross rebarrelled to 7mm rem mag. It is a wonderful rifle. It now has a flat bottom like the sporter.
 
Brass

I've tried common .300Win brass through my dies and they come out close. Might be a little short on the shoulder and headspace a bit loose, but may fireform out ok. Havent tried in my rifle.

On the buffalo website they say they resize other casings (300 H&H I bet) to make their own 280 ross :)

So I did some mathification. There are plenty of assumptions and most prices are probably low, due to american websites and not factoring in shipping BUT: here's what I got.

To make my first 100 rounds:
Lee breechlock anniv starter, $100
280 ross dies from ch4d or rcbs $120-140
.284 bullets $60
300 H&H cases range wildly from $50-100 for 100 in the states.
jug of powder $30
primers $5

so, $410 ish for my first 100. Plus the few extra cases I have already. Since the goal was to keep it under $10 a round .. great success!

since the next rounds will be bullets, primers, powder.. say I end up doing 400 rounds more, it will be down to $1.50 each.

Not bad at all :) Even with the cost of the equipment thrown in I'll be doing ok. I'm sure there will be more tools to feed my addiction.
