Ross M10 MkIII striker issue

[Gingercat]

When dry-fired how does the speed of the firing-pin's travel and force of impact appear to you, compared to other surplus arms such a Lee Enfield? Quite a few MkIII Rosses seem to have quite weak springs.

I'm guessing they were sourced in wartime from factories that didn't know or didn't care, or cared more for the Central Powers!

Many thanks for your reply. The primer impacts on the 3 cartridges fired did vary, with one much deeper impact than the other two. The speed of travel dry firing seems good and the spring itself felt pretty strong when I was working against it to disassemble the bolt. So I’m not sure whether it was a bolt closure issue. I’ve thoroughly cleaned the area of the screw threads in the receiver with Hoppes and a tooth brush, so will see if it has made a difference.

Kind regards

Mike

I would bet your deduction is correct that if the bolt was not fully forward, the spring expended most of it's energy in first closing the bolt, then striking the primer.

I happened to see an advert recently for a Ross Mk.III in decent shape over there for whopping £2100. Yikes!

Not surprised on the price. They are a very scarce rifle here and I’ve only seen a handful advertised for sale in the last few years.
