Yes, the Springfield and Vintage are combined events, but I shoot both (Vintage will be shot Saturday afternoon after the Garand match, and Springfield will be shot Sunday morning). 

Now I wish I had a separate 03A3 for the Long Range match.... things would be a lot less complicated!  Anyway, I really do appreciate all of the advice, and I hope I'm not sounding curt or crass.  I'm just trying to take all of this in.  With all of the experience I've gained in loading and shooting over the last 30 odd years, this LR shooting is a totally new deal for me, and I'm eager to learn, but definitely willing to listen to advice too.

It sounds like I'd better get a separate front sight blade that I can modify.  My 200 yard accuracy is dead on for the 200 yard setting, and I really don't want to screw with that, so I would take a different blade and tools to swap it out after shooting the Springfield match.  Any idea of how short to cut the blade as a starting point to get close?  I'll take a file to the firing line too!
