I’ve been playing with the last couple years with a .358 x 1.8” straight wall based on starline .223 basic brass. Started on it just prior to the announcement of the 350 legend. A full case of AA 1680 will push a 180 gr hornady ssp at 2600 fps out of a 26” MGM encore barrel. It’s a hammer on deer. We also have a couple of 357 maximums. Deer take very few steps. Most our shots are within 150 yards with our food plot layout. Food plot is longer but the deer don’t necessarily need to be shot much farther than 150.
