I am putting a rifle together in an odd caliber for Iowa deer season and because I do not anticipate it being used a lot I was considering fitting a second barrel. Between both calibers I am not sure the gun would get shot much. I am reasonably certain some of you have tried this so how much trouble is it and do you feel it's worth messing with? After having the options of two barrels do you even bother changing back and forth? Are there any problems that arise?
I built a couple of switch barrel MLs and after I got them shooting well in one caliber I never bothered switching barrels, not that it can't be done easily but it just wasn't practical for me.
I see a regular rifle being no different but if a guy wanted to go to the trouble to swap over it's very doable. I had two different scopes set up so I could just unclamp and switch over, zero went back very close as I had the barrels timed to the lug/ action so I could get them back exactly the same every time but as I said it just wasn't practical having an extra barrel and scope sitting in the safe to stare at.

I have a switch barreled Rem 40x with barrels in 6PPC and 22PPC. The recoil lug is pinned so it goes back the same every time. I don't have a rail on it so I just re-zero the scope when the barrels get swapped out.
I built a switch bbl on a Bat tactical action and Mcmillan stock. I switch from 7 mm Ultra, 300 Ultra and 338 Edge. Takes about 20 minutes to change calibers. Recoil lug is built onto the action of the Bat so simply thread one bbl off and another on. Allows me to shoot a variety of calibers without the expense of multiple stocks,scopes, etc
It's pretty common practice around my area. I will be doing that in a few weeks when I get my new action. I will be chambering up two barrels for this new action both in the same caliber 300wsm but two different barrel makes one Krieger and one Shilen ratchet four groove barrel I have had for some time. I want to see which one will group the best at 1,000 yards for our matches. You can't afford to waste a bunch of time testing a new barrel if it doesn't shoot proven loads then it's time to take it off and try another one simple as that. There are a ton of mediocre barrels out there but a match winning barrel is hard to come by these day's because you need to be able to shoot 10shots under 6" and most of the time 5' or smaller just to win a relay. 5 shots is pretty easy 10 shots is very tough.
What caliber you plan on building for Iowa. The 45 Raptor would be a great choice. And even the 450 Bushmaster in a bolt gun with a 22" barrel will shoot 250gr bullets up to 2500 fps without much trouble. H110 and 46grs will get you there without any pressure problems and that load is dead accurate out of my little Ruger with only a 16" barrel

I only have one gun.........a Rem. XP-100 that has two 15" barrels for it. I did not build it as a switch barrel gun. It is in 6mmBR with a 1 - 14 twist barrel and shoots (or should I say has shot) under 3" three shot groups at 500 yards with 65 gr. BR bullets. I wanted to get a higher BC bullet so I took an older 1-8" barrel, shortened it and rechambered it for 6mmBRX to shoot 105 gr bullets. The problem was, the heavier bullets with the faster twist caused too much recoil for the 6 lb. gun and the short eye relief 24X scope wanted to hit me in the eye if I was not careful So, I switched back to the 1-14 twist barrel and never switched again. In theory they are OK, but not really practical? Now with an action like an Encore or Contender, its a different story.
