combo
I imported a Baikal in 6.5 swedish under 12 gauge before they were available in Canada. It is perfect, because I reload some really light 85 grain bullets for rabbit sized animals, a regular varmint load with 85 grain bullets for beaver/coyote sized animals, and regular hunting loads for deer sized animals. The barrels are well regulated, so when deer hunting I often will have a slug in the shotty barrel for a second animal should the opportunity arise. Very happy with this setup.
I have bought 3 receivers and 6 barrels for the BRNO 300 series as a replacement for the baikal, but have not put enough time in at the range to comment on its accuracy, but it is lighter and shoulders better than the Baikal.
FWIW, I have had over a dozen Savage 24s in various configurations, and have not found one with barrel regulation good enough to rely on; I did have a really nice setup on a 24v with pivot mounts; shot the rifle barrel with the scope, and pivoted the scope away to use the irons with the shotgun. That system worked quite well.
