Once you get to the warning on the barrel, 1977, they are all the same as far as features like checkering and all the rest . After that unless they are from a short run of a rare caliber and/or configuration, they are all just "shooters".
As mentioned, actual numbers made is NOT something Ruger ever releases. However it is possible to know how many were made if they were from a wholesaler ordered short run and the wholesale announced the production figures. That includes things like the 218 Bee "S" the 38-55 "S" the 223 "A"s and the 7-08 "A"s along with SOME others. That's only with specific #1s As a general rule there is no way to know about "common" caliber/configurations.
I prefer Red pads but have to abmit that once you get the barrel warning it really doesn't matter other than cosmetically. Once you get past 1977 they are all the same as far as engineering etc other than the change in the angle at the front of the receiver that happened in 1984. Okay stainless versus breach block in the 200s. Looking at "new" #1s it appears they have gone back to blued carbon steel for carbon steel #1s since the discontinuation of the stainless/laminate #1 as a general "cataloged" item.
I was talking to Ruger two days ago on another subject but was advised that they would be making a run of "Standard Sporter "B" rifles in 300 Win Mag and 264 Win Mag within the next three weeks if anybody is interested in a "new" shooter. Whats a "run" who knows, but they are usually made in lots of 100 less what doesn't pass QC. Just a guess but I'd say a couple hundred of each??
300 H&Hs were certainly made in lower numbers but other than the older Red pads from the 70s I would consider the newer ones as Uncommon rather than Rare.
