Shooting the .303 Ross - ammunition advice?

[Jay in CA]

I'm awaiting arrival of a Ross 1905 Mark II, and I intend to shoot it.
Given the scarcity of milsurp .303 (though I keep on looking), I'd like to hear what ammunition has worked best for other Ross shooters. Commercial? Reloads only? Jacketed or cast?
I've got some Win Super X for my other .303s and I do intend to reload for this rifle if at all possible.
Thanks, and happy new year.

I have several Ross rifles. The .280 shoots great with reloads and can be downloaded a bit. My question is about the .303 military version, where I have shot reloads and factory Greek. But given the scarcity of milsurp ammo, I want to reload. My rifle has a large chamber. The cases come out with necks 10 thou or so too large to even enter a resizing die. How have people dealt with this problem? Have you gotten RCBS to make special dies? Does it take two resizing passes to get the necks down to .311? Other solutions or suggestions.
Thanks, Jay in CA

You might try a set of the Lee Collet Dies. These work quite well in a Ross, and even the SMLE if you use the same brass that was originally fired in that rifle. Mix it up, and you have trouble. These Collet Dies neck size only by squeezing the neck of the case inward to contact a mandrel in the center of the die. This resizing die, plus the "dead length" seating die results in some very accurate ammunition.
