Ross M10 Sporter needs scope

I was able to use a one piece tasco mount for a savage 110 on an old 1910 that I had years ago. I had to do some fitting at the rear of the mount, but it worked good for me. Not sure if there are any of those old tasco mounts floating around yet or not. ( at one time SIR was selling them off for 99 cents ). Hope this helps a bit.....catnip.
 
Hi again , I used what I had available at the time. Used an existing hole in the rear sight bridge and drilled two new ones up front for a total of 3 screws. This is fine for .303 recoil, but if you have a true M10 I am assuming it is in 280 Ross, and would require at least one more screw on the mount, (in my opinion ,anyway). I don't know if those old mounts are long enough to get that extra screw at the back. I'm thinking a good 'smith might be worth his cost here. Let us know how you make out. .....catnip.
 
Most decent gunsmiths will have blank rail in stock that can be cut to length and drilled where you want, the only thing I would be looking at first is if the cases are ejected straight up (same as the winchester 94) which may cause an ejection problem. Another thought is to have the base silver soldered onto the receiver by a competent person.
 
M10 .280? If it is in decent condition, it has too much collector value to be drilling holes in it.

Sported Mk. III .303 service rifle? Not so much.

A flat bottomed base can be fitted to the rear sight base. Receiver ring can be drilled and tapped. Note that the receiver ring isn't exactly cylindrical. Base might need fitting.
A good jig is a real help in getting the holes in a straight line. Trick is to get both bases the proper height. Rear base being flat bottomed might be easier to adjust for height.
A side mount could be adapted. Note the angle of the left sidewall. It would be necessary to fit an adapter, or alter a side mount base to suit.

tinbird - consider the location of Ross extractor and ejector - is one going to eject straight up like a '94? Silver solder requires red heat. Really bad idea on a heat treated receiver ring right above the locking lug abutments.
 
Tiriaq is tight. As the owner of a .280 Ross factory sporter, it is far too valuable to go drilling holes in. It is sad because it shoots so well it could use one.
Even a .303 Brit, in factory sporter , should not be drilled in my opinion.
An altered military rifle however is not going to be lessened in value.
I've see one fellow use an altered rear sight bridge with a single ring to hold a reproduction Russian scope on a sportered service gun.
