Curious. I know the Sherman holds a few more grains of powder. However,on a regular Mod 70 Long Action, in 7x57, the COAL is much less than a Mod 700 LA, fact. So limited to the magazine (SAAMI COAL of the Nosler AI) So, if one wanted to rebarrel to 24", have the standard magazine/bolt stop changed out, etc, anyone guess just how much more speed the Sherman would have over the NoslerAI? For me, if the gain was not more than 50fps it falls to the NoslerAI. BUT...if we are talking 100fps, well, that tickles my fancy! ha Anyone have a good idea of the gain, if any? Thanks guys.
