After much angst, I have decided my next FN Mauser 98 project will be in 7x57. My Gunsmith will soon have a standard spec. 7x57 Reamer.

I will be trying to utilise 140 grain projectiles for light to medium game and wonder if there is an optimum barrel length to obtain velocity with this round. Handling a long barrel doesn't worry me. Is there a point of diminishing returns with this cartridge ?
