The all copper bullets penetrate like heavier regular cup and core bullets. The 200 XPB should work fine for you. I use 225 XPB's in a Ruger Blackhawk .45 Colt and have never recovered a bullet from a deer. They make a great wound channel too.
Like a condor is going to pick up and eat a 300 grain lead bullet! I mean, I can see the problem when using frangible bullets that leave lead fragments in the meat or guts - I don't like eating lead either so I use all Barnes bullets in my high powered rifles even though they are not required in Washington. I even use a 290g Barnes .451 in my 50 cal. muzzleloader - they are extremely accurate in MMP sabots, expand instantly, and kill way quick. I don't use them in my 44 mag, as you simply can't get enough powder in the case to get the velocity you need for decent range and penetration. I instead use 310 grain LFN lead cast bullets, but I can do that in Washington. But obviously you will have to do what you have to do.
Whatever you do, don't use any of the other (Hornady, Nosler, etc.) brands that are made out of gliding metal. They basically will not expand as they are quite a bit harder than copper, and since you are unlikely to get more than a 200 grain bullet in the case without excessively compressing powder, you need that expansion if you are going to kill big game consistently.
