1905 Ross buldging brass

[bagograss]

That does seem vary close just the shoulder diameter is so far off. I just tried sizing with my 303 brit dies and only going part way in so not sizing the whole case. I loaded them with some cast 100gr and trail boss they seem to chamber nice and not stretch out I haven't had to trim in 3 loads so far.

bagograss, I have seen quite a few early Ross Mk II rifles with chambers reamed out similar to yours, including a couple of factory sporters. From what I can see you are heading in the right direction in dealing with it. As long as your not splitting cases, you`ll be alright.

Interesting rifle you have there. Would it be possible to see some more pictures please. (full length, front sight etc.) Looks like a later Mk II** action, bolt, trigger mated to a very early barrel. If this the case, I wonder how this would have been done, as the threads would be very different.

Haha good to know I'm not the only one with an oddball barrel. I started just pushing them less into the sizing die seems to work good they chamber nice and I'm on the 4th reload with no lost cases. I've just been shooting cast 100gr bullets in it tho at low velocity.

Any chance on more pics of your rifle?

What markings on on the barrel over the chamber?

Hi I have a 1905 Ross sprtized in 303 brit. I've read that they had the chambers reamed to make extraction easier. The one I have only puffes the shoulder and neck is this normal? The rest of the case stays almost in spec. It puffes the neck so much I can fit the neck of a live round in it. This may be normal but I'm new to the 1905 model and my 280 Ross almost stays all in spec when fired. This just seem extreme or maybe it was chambered for a different round? Any insights on this would be vary helpful. Thanks!

I had an mkII 5* that when fired produced a case that looks identical to yours. I was able to reload the cases by running them into a std .303 sizer die. Lube the case generously inside the neck and the outside case body, then run into and out of the sizer quickly and firmly as it takes a fair bit of pressure to size that well oversized case back to normal dimensions.

I don't know what your case life would be, but if you anneal the neck and shoulder after about the 3rd firing, case life should be ok, and the sizing will go easier. I was able to resize and fire each case 3 times before annealing, but use your own judgement there.

I don't know what your case life would be,

If you're fireforming the cases like that with each shot, it won't be too much I think. But with .303, it ain't great anyway...

Thanks for the info. It really has no markings left when it was sportized most where sanded off.

Even though it has been polished, you can still see the year (1906) over D ^ C on left side over the chamber. Only the MK I and very early MK II were marked this way.

How long is the barrel and what does the front sight sight look like?

[bagograss]

The barrel is 21 3/8" to the front of the reciver. The front sight is soldered on and looks like a long sport style sight. I'll try to get a pic up in a day or two
