i am in the process of building a new 7mm for 1200+ yards (ive been debating what cartridge to go with for the last three months) and i am going to use the 180 burgers. i will be using a 26" broughton and i am looking to push the 180s at 3100. which cartridge would be best? i was going to do the 7 LRM (gunwerks cartridge) but i dont know anything about it. i am like everybody else that wants good barrel life, and accuracy. thanks for your time
