Wow you have a whole bunch of $$ just tied up in gear! Not that its a bad thing. And IMO if you're going to do something you should do it right. And if it takes extra stuff to do it and you can afford it I say more power to you.
All these "tools of the trade" is the reason I just prefer casual shooting. I did the competitive shooting back in the 80s and it was fun. Now it seems things are getting more and more complicated. BTW that is one cool looking rifle.
