My rifles have 26" barrels,and remington does quote the 7mmRUM data with 26" barrels.After all,26" is the standard barrel length for the 7mmRUM and the 7mmstw,so data for 26" barrels should be used in a comparison.I didn't see you ask the man just what barrel lengthhe was using,or what elevation he was using for his data.High elevation and thin airdoes have an effect on trajectory and velocity remaining.That might have been the proper thing to do before questioning his data.By the way,what barrel lengths are listed for the loads that you keep quoting?Could they be for 26" or longerbarrels?Just how many factory 30-06 rifles come with 26" barrels.Perhaps to keep all comparisons realistic,all data should be based on the standard barrel length for each cartridge.Perhaps we should also only use data that we ourself have seen verified by a chronograph andthat use thestandard length barrels for the cartridge.Otherwise this data is nothing more than unproven theory.
