I went a slightly different route than the legend. I built two different 357 Rimless at 1.79” case length using .358 bullets. One is in an Encore And the other is in a Remington 700. I’m experimenting still but am running a 180 gr Hornady SSP at 2600 FPS using 35.0 gr of AA1680 in the Encore 26” MGM barrel. Ran out of Time to finish the 700 but will be my winter project. I played with some 150 core lokts checking speeds and they ran around 2850-2870 FPS range. Have not checked the 150 for accuracy just acquiring load data. I did harvest a big doe Friday evening quartering towards me hitting her in the shoulder ripping off the top of her heart. Whole front leg was junk. She did a nose diving run for 15 yards and rolled face first dead. It piled drives her. Bullet exited. Best part was I watched it all through the scope.
