Ross
Man I have got to get m1e one of those.!
If you do get one, you will find that you have a very accurate, fairly heavy barreled rifle, with a very strong action and one of the best trigger systems of any Military rifle built. The barrel contour was borrowed from the 1905 Ross Military Mark II**, a rifle that the Canadians ruled the Bisley Ranges with for five years.
The 1910 Ross (M-10) Mark III rifle was used as a basis for the .280 Ross cartridge, the Magnum of the day. It was tested to over 100,000 psi pressure.
You have to understand that these Ross rifles were MILITARY rifles, and chambers were generous so that dirty, soiled and crappy MILITARY ammunition could be shoved into them. Most have enlarged chambers, so NECK SIZING your brass only is the way to go. If you have more than one Ross, you keep your brass separated and use only the brass fired in that particular rifle for that rifle. Pick-up brass can be full length sized ONCE with little effects, but if you full length size your .303 brass all the time, you are going to end up with a seperated case in your chamber. Count on it!
Anyone shooting the .303 regularly should have a broken case extractor in their range kit. It costs less than $25 and will save a lot of grief, and possibly a ruined chamber. You see posts where someone has used a threading tap to extract a case, but there is an excellent chance that it could ruin the chamber by digging into the chamber walls. Don't do it!
Otherwise, observing the normal safety precautions, a Ross is a great rifle to shoot. With all the rumors, mythology, and B.S. information on the Internet about the dangers of the Ross, when you appear on the range with one, poorly informed people tend to retreat to a safe distance. They expect to see a smoking crater after you touch off the first round.
Bring extra ammunition to the range. After a while, some brave, foolhardy individual will clue in to the fact that this "bomb" you are shooting is making some pretty respectable groups downrange, and will ask to fire it. Then, you will see some smiles after he does.
