The 358 Winchester should be a Deer and Hog slayer.
I am a Big 35 fan. I have owned a 35 Bullberry for several years. It is a 375 Winchester case blown out and necked down to 35 caliber. A 35 Remington Rimmed for all practical purposes. My latest barrel is an MGM 357 Maximum. I went with a 13 Inch on it.

When I get around to upgrading to an Encore I will have a big decision to make between a 338 Federal and a 358 Winchester. The 358 has a lot more bullets, but you only need ONE that works well. One bullet that shoots well and will expand at the range you limit yourself to shoot is all you need.

MGM looks to be a very good choice on barrels at this time. I have barrels by Bullberry, JD Jones, as well as MGM. All are good from what I can tell, but MGM's prices are better.

Your build looks good, enjoy that 358.
