[QUOTE="jarnold37, post: 2143145, member: 29241"] It seems that in the RUM family-the 7 rum is the most finicky to load for. It is overbore. Efficiency is lost when you have to load for big amount of powder to exit out a small hole. You have to use slower powder and you lose what you have gained. The 300 Ultra Mag is not so overbore and is a little easier to load for. The 338 UM is a very good combination of better efficiency and is easier to find good load. I ordered the brass and was ready to try a 375 Ultra Mag and then the market messed up and I stopped. I have read it is very balanced between case capacity and bore diameter and said it is the most accurate of all the RUMS. [/QUOTE]
