It’s what the 325wsm should have been. As far as ballistics go it’s a good one. The 375wsm is very interesting as well and really starts to take some of my hate away from the wsm line.
If your a WSM fan already you will probably love it and it’s more of a good thing over a 300-325wsm.
If your throwing a dart at the wall wanting to try something new it might not be where I would start.
WSM series of cases IMO are to big for a short action and to small for a long….. you loose 1 round of mag capacity in most cases and every one I have ever handled fed and operated as smooth as a 3 point turn……. The .35 or .375 may be the cure to that problem though.
I don't feel the call to the Whelen is relevant anymore. Don't get me wrong, I am a Whelen fan, and have owned and hunted with several over the years, including a beautiful Ruger No.1... i like pretty much all .358 catridges... but these days, there is no issue with finding .300 WSM brass, many have it already on their bench, as I did, several hundred in fact... so as far as "easy" goes, it is just as easy to build and Feed a Sambar as it is a Whelen, and let's be honest, a Sambar is much cooler! The question of action length can be easily answered... go long. I built my .375 WSM on a Ruger Mark II Stainless action that started life as a 7 Rm Mag, twirled on a 24" Bob Jury #3 barrel and added an Alskan Arms Coffin mag plate to bring the mag capacity back to four rounds. As I said earlier, it is a corker cartridge and the case is ideal for the lighter .375 bullets, up to 300 grain. I liked my Sambar alot, and shot many bears with it and a couple moose, but I LOVE this .375 WSM it is hyper accurate and pleasant to shoot... to be honest the .358-375 Ruger was a smidge too much of a good thing for where and how I hunt... If I were left of center it would have stayed right here... but the .375 WSM isn't going anywhere for the foreseeable future... I took a medium bear and moose with it, and will test it out on PG in a couple months. I also put together a new .458 WM Stainless Carbine, to complement my RSM in .458 Lott, and shot a doe with it this fall, just for S&G... the .458 WM will mostly be carried while guiding and hunting bears in the Boreal... I prefer big chunks of lead at slower speeds to the light and zippy group at least for bears, less messy and just as effective.
Basically, if you reload, I say go ahead and do the Sambar... or the .375, you won't regret either.
