if the new fill is more dense?
if the new fill is more dense and will make the .50 cal fly like a .68 cal . why not put that fill in a .68 cal and make the .68cal fly better then we have it now?
on a side note if the new .50 cal has any less range 15-20 feet then i say NO, if it breaks any less then the .68cal i say NO , if the .50 cal works the same as a .68cal and save money GREAT.
