It looks like Ruger has moved the Number 1 into limited production in just a few chamberings. This may drive me to pick up another if I come across one I like. While my RSI in 30-06 is one of my all time favorite rifles, I like the way the 1-A points and and handles. I was sorely tempted by the 1-A in 303 a couple of years ago. And, I have regretted not getting a Number 3 in 30-40 when it was still in production. HOWEVER, If you ever wanted to get a Number 1 (Tropical) chambered in 275 Rigby, now is your chance. As we all know, the 275 Rigby is a much better elephant cartridge than the more mundane 7 x 57 (http://www.ruger.com/products/no1DE/specSheets/11399.html).
