Does Draw weight increase your range.

Ditto on the long range practice. When you shoot a lot at 40, 50, 60 yards, those 20 yard shots are easy.

True. I shoot very well at close range, after shooting a bunch of arrows from a distance. Besides, it feels godlike to hit the bullseye from far, far away!

I think we have two camps talking about two different things.  
-Will a heavier bow improve your accuracy out at longer ranges ?  No only practice will do that.  Accuracy obviously has to be there or all the weight in the world isn't going to help.  
-Will a heavier bow allow you to literally shoot the arrow farther?   Well, depends on whether you start messing with the arrow weight.    If you shoot lighter and lighter arrows to help compensate  for a low poundage bow  then you can probably shoot just as far,  without a ridiculous amount of holdover /arc.  But assuming equal arrow specs a heavier bow is going to extend your range.
Take it too the extreme,  and picture yourself shooting an average weight hunting arrow (500-600 gr?)  out of your kids toy suction cup bow.   It's not going very far.  Now bump up to a 25# youth bow,  it will go a little further and flatter.   Keep going up the scale and the heavier weight bow is going to extend your range.   Not going to do anything for your accuracy or extend your "effective hunting range"  but it will shoot farther and flatter.

Heavier draw weight increases "effective" hunting range.
