I guns in both calibers. I liked them both. The 358 was a Ruger 77, the 356 was a Winchester. I killed a nice buck at a bit over 250 yards with the 356 with 250 grainers, and quite a few others closer with that rifle. That was the longest shot I've ever made at a whitetail and with a bullet that sloped like a rainbow. I had very good luck with the Speer FP 220 grain bullets in the 356. You need flat points in that tube magazine. Wish I still had the Winchester. I liked the 358 but got a hankering for a Whelen, so off it went. I don't remember the powders I used, but I remember my best load with the 220 Speer was well below max. Even up close that bullet went through even big deer. I say that 'even up close' because some were just off the muzzle when I shot them. The Winchester will be great in PA laurel thickets.
Be nice and work hard, you never have enough time or friends.
