Either one, my friend. I knew two guys who used them at Second Ypres, St. Julien sector (the gas attack) and they shot their Rosses until they were too hot to hold, grabbed another Ross and shot it until it was too hot to hold, went back to their original rifles.
In competition, have used a 1910 Ross at the 2-man Iron Sight at CFB Shilo. This is a miserable, mean, cruel shoot, 2-man teams, about 40 reactive targets at distances estimated (very roughly) to be 80 yds to 400 yds (actually, there was a 21-inch plate at 500 metres). Timed, of course: hits count first, time second. Utterly cruel on the humans, rough on the rifles. Rosses came through just fine after 8 minutes and 30 seconds of rapid-fire. If I remember rightly, I think Stencollector was there that day. We had a couple of very warm rifles at the conclusion, but we did come in 10th place.... and we were the only team with 2 bolt rifles.
Fun!
That's what Rosses and SMLEs both are best at! Can't beat 'em!
