There are some old M700 BDL's out there with a 24" tube, though not many as the owners tend to hold on to them. Rem. std cals are 22" for the most part, but wisely the 24" BDL & Var. Special was 24", they were the first to introduce the wildcat as a std. round
& they understood it's ballistics. Also the Ruger 77 has a 24" barrel, the other Ruger std. cal 77';s I am aware of have 22" tubes, nice to see that Ruger also understood the round & even gave us a fatter barrel, more like a mag, nice & smart. My brother had a wood
stock version he bought back in the mid 70's (seen many a varmit & Deer meet their doom by this gun), my nephew owns it now &
it's a shooter. I had a Ruger Stainless with the skeleton stock, had it bedded but still was not accurate enough to keep, but I have seen others that are.
