Hi there guys. I'm in the process of building a .338 Edge. Ive purchased a DBM bottom metal from Dave out at PT&G in the 3.775" length but I'm learning that on the Edge that can be limiting as most loads run in the 3.80ish" range. I can purchase the CIP length of 3.850". Was wanting to know what the actual internal measurements were for COAL on the Accurate Mag magazine in 3.850"? If it is actually 3.850" or less and if the 3.850 is required to take full advantage of the Edge performance gain over the .338 RUM or if the 3.775" will do fine? Thanks guys.
