I dont get the hostility towards these new rounds , yeah theres no big reason to get rid of a good shooting 243 you might already have , but if you are a handloader and looking at a new rifle , what reason is there to choose the 243 over a Creedmoor ?

the Creedmoor is simply a better designed case , a sharper shoulder with a bit longer neck will get you better brass life , less trimming , better throat life , and more flexibility when seating bullets in a short action

some old fudds may not like it , but the Creedmoor case is not going to go away.....
