I avoid handloading like the plague but completely understand the purpose and value. I had excellent results with Sellier & Bellot factory 7x57 ammo with the 175gr nosler partition. It worked on bear, kudu, zebra, 9 impala, steinbok, hyena, baboon, etc. Just an awesome round. My 23" barreled single shot chornographed them at 2437fps so it is certainly not the fastest load that could be made for this rifle but it was plenty for all my purposes. Did I mention that the S&B 175gr partition ammo is cheap? This caliber has expensive brass to begin with so buying loaded ammo and saving the brass isn't such a bad plan either?
I'd really like to get my hands on 175gr or 180gr FMJ ammunition regulated to the same POI as my 175gr partition for a wide variety of uses. (not the use Karamojo Bell had in mind!) It's on the list if I ever get back to handloading.
