I can't really offer a specific answer to your first question because my Colt seems to like everything I have fed it so far.  As far as accuracy goes, you should be able to plink clay birds at 100 yards.

what i have found out is that you can get two exact barrels in every which way and each prefer different ammo.



the best way is to by a box of each and have at it and see for yourself which your rifle likes best.

I use Rainier 147gr plated flat points.  Work great in my 635.  Win 231 is my powder of choice.

For plain old blasting,  stick with 115gr,  don't cost a whole lot, 124's good also, though cost a little more (if you load your own).

147's be good for steel or suppressor use, but usually drop like a rock out to 100yd, where the higher velocity 115/124 are straighter flight.
