    That's the reason I went to the 300. 308 on steroids. I've been shooting 300wsm for 16 yrs.

    Had both.

    Had a win mag custom rifle.

    Too big and too long for my liking. Whoever ended up with it got a minter of a custom rifle.

    Had a 300wsm. Not for very long as it just wasn't my thing. Ended up back where I started off initially and went to a 7mm round.

    If you are considering something that shoots factory ammo which you do specify consider things like 7mm rem mag, 280 or of course 30-06

    There's not a lot in it in terms of performance when comparing factory ammo. The WSM uses less powder and has a more efficient case design, sure - but it's also loaded to higher pressure and that's mostly what closes the gap against the 300WM (If you ever do start reloading, 300WM has plenty of untapped potential horsepower there - plus there's better brass available).

    On paper, recoil energy is similar. Recoil of the WSM is meant to be a bit snappier as it uses faster powders in a shorter fatter column, at higher pressure - the WM, using slower powders, a taller case, and lower pressure, produces more of a heave. Both will still kick the shit out of you unbraked or unsuppressed and you'd be hard pressed to tell them apart. Rifle weight and how linear the recoil is, makes a larger difference to felt recoil.

    Depending on the rifle model, there's little to no difference in action weight and length e.g. Tikka's are all the same. If the manufacturer produces different length actions, yeah there might a small saving. We're talking a few ounces and perhaps an inch though.

    Funnily enough some of the reading about 300 H+H suggests more of the same with many writers and even one of our forum members @bunji, saying how relatively soft shooting they are.
    Read something recently on about the long tapered neck creating a different burn impulse of the powder down 5he barrel not in the case.
    That's the theory anyway but does sound logical.

    I have a win mag, wishing I went with a Wsm so I could cut the barrel shorter

    Get the wsm, they just look sexy stock up on whatever ammo it likes, save the brass, buy some dies and get a mate to reload if/when factory ammo becomes hard to get.

    That's for all the responses guys. Much appreciated!

    In answer to some of the questions raised here...

    I have a 7mm-08 Montana for most hunting and that will be my main rifle for bush stalking, and general hunting - being Reds (bush and bush/openish country) and Fallow (if I can find the sneaky buggers in the bush!). It serves me fine truth be told, but I cut my teeth on a 308 Brno ZKK 601 and at the time of my Kimber purchase couldn't find a 308 Kimber so went with the 7mm-08 instead as that was the caliber in stock at the time. Can't exactly put a finger on why but on it but I prefer a 30cal.

    My intended quarry for the Win Mag or WSM would be Red Stags in the roar, in the open past 300m. I know that it is doable with a 7mm-08 out to a certain distance, however I like the idea of having a bit more power on my side.

    Do I NEED another rifle? Probably not. Do I WANT another rifle - simple answer is YES, Yes I do.

    The other calibers suggested (7mm-Rem Mag, 280, 30-06 for example) would do well, however trying to source one of those in the Kimber Montana range (if I can even find them in NZ at the moment) may be problematic. Can't say I'm a big fan of the newer Kimber painted stocks or the Hunter model stock.

    Now, full disclosure here, i didn't want to muddy the waters up front, but I actually own a 300WSM Kimber Montana (shortened by previous owner to 20 inches, fitted with a Hardy Magnum Suppressor and Talley rings). I thought I did well buying it as a package for $1700 in February for a Wapiti Trip so jumped on it. Here it is unscoped with my 7mm-08 for comparison (also a 20 inch barrel but with ATec Suppressor).

    I've the taken the WSM to the range for a bit of a play and felt it quite comfortable to shoot.

    My original question arose due to trying to find ammo for it. I've found the selection of ammo where I live to be a bit on the lean side and recently located a Kimber Montana in 300 Win Mag, but for $200 more than my WSM and without a suppressor. I was toying with the idea before getting too attached to the WSM that perhaps a Win Mag may be the way to go. The comments here have helped firm up my thought processes greatly though. I think I'll stick with the WSM for the foreseeable, just means I need to forward plan my ammo purchases and not leave it to the last minute as chances are ammo might be a bit scarce at times.

    Perhaps one day I'll head down the rabbit hole of reloading for it, although after following @Tikka7mm08 and his marathon 280AI load development I'm not so sure....

    Thanks again for all the comments/advice!

    Do you want to try a couple of handloads? I can send you a couple of 150gr and 200gr to try, only if they chamber? Not hot loads pretty mild.

    Thanks for the offer, the rifle also came with a load developed from Rivers to Ranges. so I have something to work with if I head down that path.

    Don't bother if you're not a reloader. But it is great to get into. Certainly Kimber MA 280AI one of the more challenging rifles but the Montana 308 wasn't too bad at all.

    If it came with load development find someone to load for you would be the best answer, you pay the same per round as factory ammo and get a far superior product

    Greetings Kimber 7mm-08,
    Handloading is as difficult or as simple as you make it. I've been involved in loading both the .300 Win Mag and the 7mm-08 and have found both easy to load for. The .300 WSM should be no different. I am also a minimalist when it comes to load development having long since abandoned endless series of small increments of powder charge in favour of concentrating on the target velocity area. Handloading does get over the problem of sporadic shortages.
    Regards Grandpamac.

    I was running 167 grain Scenars but have switched to Hornady BT Match, being as good in performance but cheaper and easier to obtain.
