What ever floats your boat is fine! I like a 24" barrel in my bolt rifles, and a 26" in my single shots (Ruger No1 375 H&H belted), and double rifles (375 Flanged), but for a speciality rifle for crawling into the thick stuff, I like a 20" Medium heavy barrel, all with a 1, in 12" twist, and all with iron sights on the barrel!

I have a friend , who is a PH in Zimbabwe, who has a 458 Win Mag Mod 70, in a synthetic stock, and with a 20" medium heavy barrel, with good Iron sights, for the tight bush for wounded cats. His camp staff calls it "THE BLACK BITCH"! It works, however, for the purpose he built it!
