Because why not ! I owned 2 Marlin 336ER's, one that I hunted with and one that was NIB that stayed that way. My divorce in '07 cost me both of them along with about 48 other of my then 62 long gun collection, but that's another story for another forum. The .356 in a 7lb rifle always stung a little at the range in a short sleeve shirt, but I don't believe there is anything in N.A. that it can't take within reasonable ranges and with proper shot placement. While I have not been able to replace my Marlin 336ER's (reasonably), since 2018 when I finally got back on my feet, and until now, have managed to add 3 Browning BLR's in .358 to my safes, one a 2012 stainless / synthetic take-down and the other 2 both from 1974. Browning had the wisdom to install a factory pad rather than a steel or plastic butt plate. It is heavier than the 336 for sure, but with the locking lug, pad, and added weight, I enjoy shooting these more than I ever did my Marlins even though I miss them and hope to one day find one at a decent price. Yes, for all intents and purposes, they are essentially the same round. I saw several comments about the .348 and I finally checked that one off my bucket list this past Sunday, last minute, as the gun show was closing down. I haven't fired it yet, but I've read everything you could read on this round and the Winchester 71 and can't wait to take it out to the range. Thankfully, it came with a boatload of vintage full boxes of ammo which I'll never use, handloads which I will, several incomplete boxes of factory ammo which I will also shoot, dies, nearly 50 pieces of once fired brass, and 3 boxes of 100 Hornady 200gr bullets which they no longer even make. I'll be working on loading up the brass within the next couple of weeks. It was factory drilled and tapped for a receiver side mount peep sight, which I will get if I must, but I'm going to see what she'll do with the irons... actually, I'm going to see what I can do with them as I really only use scopes at this point... and considering my eyesight, I'm not so optimistic. Thankfully, my hunting shot distances have never been more than about 85 yards, so I may get away with taking the lady out next season. Totally off topic: I hunted with my 1935 Savage 99 in 250 Savage this past season for the first time. Yeah... I know it's a quarter bore, but with next to zero recoil, the hydrostatic shock of an 87 grain hand loaded pill moving at a measured average of 3,045 FPS did more internal damage to the heart and lungs than everything I've ever hunted with before which were all .30 Cal and higher. Impressive actually. The hearts AND lungs were bloody pulp. It left .25" hole on the way in, a .375" hole with a 4" bruise on the inside of the ribs on the way out, and even bruised the rears of the front shoulder meat. Very little blood at all on the exit wound. The deer literally hemorrhaged internally. One did a back flip and was DRT, the other didn't go 20 feet. I've never seen anything like it, but I'm told the .243 does the same thing and I'm sure other fast moving smaller bullets are likely the same. Bought a 70's vintage BLR in .243 a few weeks ago and I'm gonna give that a whirl next season. Thank you all for sharing your experiences. I guess the bottom line will always be: Hunt with what you like at reasonable for cartridge distances and make the shots count. You will never be disappointed.
