RE:joe
No ammo is all very different most use the standard loads and others do not, depends also where they buy their bullets from. Check out some of the reloading forum and you will be amazed at how complex it really gets. BTW AMMO is spelled AMMO not AMO.
As for recoil it depends, a 158gr bullet versus a 110 gr bullet loaded into a standard load for 357 can differ very much in recoil, I call it "FELT RECOIL" and " PERCIEVED RECOIL" just so I can explain it. heavier grain loads will usually have more FELT recoil such as a 158 grain .357mag versus a 110grain .357mag has more PERCIEVED recoil (big flash). Some companies use different powders to achieve different velocities for different grain bullets also there is a difference in jacketed and gas checked loads. its very complex, the best thing is to try out a couple different loads and brands.
