The #1 rifles are pretty much a "niche" rifle, for a certain type of shooter. I fit that niche perfectly.
There are many other rifle types in my rack, but the #1 has always spoken to me and I heed its call. Soon there will be a new one here, in .303 British, as Ruger has announced production in that caliber. The stock number will be 11348, and the model will be #1A (the lightweight one). This seems to be a match made in heaven, in my opinion. I placed my order the day I heard of the new chambering.
Not long ago, I was testing some loads in a light Interarms Mark X .223, grouping around the 1" area but nothing spectacular. After finishing with the .223, the #1H in .416 Rigby was put to use. Firing 370-grain cast bullets at 2050 fps, the .416 fired a TEN-shot 100-yard group of 7/8"...one of the proverbial ragged-hole groups, and better than my best .223 group of the day.
The #1 has strength, versatility, and above all else, CLASS.
