Since the 30 Boo Boo is winning 1000yd matches, I just wonder why no one is running the 30 Newton. Very similar in performance and since the Boo Boo takes a special bolt face and the 30 Newton will work with standard mag bolt face, seems it would be easier to go with Newton. Most people has never heard of the Newton but with todays powders and high BC bullets, it might be worth looking into. Alot of wildcats are designed when really there are some cartridges that people never heard of that they are just duplicating the performance of.
