Not to run this into the ground but is there an engineering reason that high SD bullets and rifles to fire them are not made? Just for the record by my clculations a 100 gr. 224 dia bullet would have a SD of .279.
I also noticed that 24 & 25 cal. have poor SDs( heavy bullets just are not available). But as you can see in the bullet catalogs once you get to 26cal. weight for dia. jumps up considerably. WHY, WHy, Why???? Marketing reasons or too much bearing surface on the rifling?
Someone has got to know.
