Excellent choices on rifle, mod & scope.
For field shooting and most target work - ie odd session at local club you are well 'within the zone'. For 99.9% of sensible stalking needs double or triple that group isn't ever going to present an issue. It is arguable that groups below circa 1" for a hunting rifle only realistically have one ( albeit important ) benefit - CONFIDENCE.
The C word is a huge part of the shooting system. It comes across that you have it in that rifle - sleep soundly!
The reloading v factory debate is as valid and as 'essential' part of the talking stalking side of things as anything else. But in that sentence, emphasis should be placed on the talking bit.
For most stalkers, the economics of the debate do not really come into it to any great extent. By the time you get set up, test loads etc you have the investment that would have purchased a good few years worth of ammo.
Consistency and supply? Being a tiny market in a big world means you can hit just as many issues trying to source primers etc as you would factory ammo at times. With ammo like Sako, the chances of a batch change affecting performance to a noticeable extent are pretty low. If its a real worry then talk to your supplier - we are RFDs and will happily do a quote for same batch ammo in quantity, holding it for you and releasing onto your ticket as needs and permissible quantities require. Most good RFDs will do the same.
So ditch reloading? By no means. It is a great way to tailor a load to your needs/ rifle. As has been said there is a great feeling in taking quarry with a set up that you made. And most importantly it is a great hobby in its own right.
But for me the best reason for reloading is - just 'cos I want to.
