Ruger 77 RSI calibers?

[BigUglyMan]

It depends on who you ask...

RSI = Ruger Sights International

OR

RSI = Rifle Sights International

The first two words are self explanatory and International designates the Mannlicher style full stock.

I'd think the second interpretation would make the most sense.

I have always believed" it to be "Rifle Sights International" but I have seen some experienced gun writers use Ruger rather than Rifle...
