The 303 is on the website under dealer exclusives.
If Ruger is using 308 barrels, that gives you a great choice of bullets to load into your cases.
other than that the 303 is very similar to 308 win in ballistics and with the large rim it makes sence in a single shot.
I thought it would be neat if Ruger would come out with a model No 2. Short barrel of the No 3 with the pistol grip of the No1 and a plain finnish, no checkering, with flat finnish in calibers like 30-40K, 30-30, 303Brit, 7.62X54R, 348 Win and 45-70. and price them at and MSRP of $750.
Basicly what the man above has.
