I once had a multitool that was reported to "do it all". One day I flipped out the blade, started to pry a little, and BAM! - it broke. Tool was useless without that blade. I went and bought a Gerber that could do fewer jobs, but what it could do outperformed any other tool out there. All was good with the world again. Does that gun come in pastel colors?
I like the savage over/under .223/12ga. I had a .22/20 ga. It's hard to fault the .223/12ga. cartridge choices. However, tacking on all those accessories to tote around all the time is ridiculous. Nothing wrong with having them stashed for use if neccesary though. JMHO of course.
Yeah, a versatile setup, but I'd use a soft case with pockets for the accessories. I have shot a single-shot shotgun with a .45ACP insert barrel - nifty and fun, and very quiet! But it took some getting use to for accuracy - the POI was quite different than the shot pattern, using the same sights! He'd better get plenty of practice - and different ammo loads will change POI too. Heck, he'll need a pocket notebook with sighting info for each barrel/adapter and type of ammo!
I'm with Tac and Brokor. Anything that does everything tends toward doing nothing well. (Not to mention that 45-70 in that light a package will discourage ever using it that way again.) Interesting, for all that. It requires planning and fiddling with parts and pieces before going afield, but might do in some situations. The only advantage I see over a selection of other guns is ease of storage. More scoop - http://www.savage24.com/
Carrying all that stuff, just to shoot multiple calibers seems to be "a lot junk in the trunk". Too many pieces to loose or break just when you need them.
Sounds like BS to me. If the gun is anything like the one I have, they do not have choke tubes and stocks are wood and not hollow enough to store much in unless you hollowed it out yourself. Amount of inserts with multiple types of rounds sound like a disaster waiting to happen if you get into a stressful situation or let someone unfamiliar use it. Also wanted to make a joke about inserting but will hold off for now.
what he said, plus think about all the different types of ammo you have to carry just to be able to use all those adapters. I'd stick with the 223/12 ga and substitute buckshot and slugs in place of all those adapters.
the rifle/shotgun combo already has a lot covered between 0-400+ meters. i'd trade all the ancillary stuff for a pistol on the hip. and pack away more ammo to feed fewer required calibers.
