OK i have the stuff to build my heavy 600 yard rifle. well almost. The action will be here on Monday. Anyway i thought about doing a 7mm but several experienced fellas here suggest i stick with the BR or variants. I have a dasher already so i am thinking about the BRX. The fella thats doing my chamber has a reamer but he suggests that i go with a custom die. Not sure i can afford that at this time. I was under the impression that i could use my redding type s 6BR dies. Is this not a good idea? I could probably come up with the cash for the custom die if needed. If i dont go with the BRX a good friend of mine has a dasher reamer for a .266 neck. I may go this way. Also real quick fellas. whats the opinion on the redding seat dies (standard) If i go with the .266 dasher i will have to upgrade my dasher FL size die to a redding bushing die. Sinclair has a few in stock but they are a set. I really like my forster seat die and wasnt wanting to have to buy another unless i would decide to go with a wilson. Sorry for all the questions fellas. I just cant stop thinking about the coming season!! Lee
