.300 win short mag.

[jiminpa]

anyone using one yet? likes/dislikes? i got a chance to buy a browning with boss in this caliber and want to hear the results of this cartridge.

As far as the cartridge goes, it's not any different than a .300 Win. Mag.  In fact, they are virtually ballistically identical.

Yes, It is essentially ballisticaly identical to the 300 win. mag. ballistically BUT that is what makes it superior to the 300 Win. Mag.

A short action chambering that compares favorably to a standard or long action chambering is very desirable. { More ridgid action, shorter bolt pull, shorter OAL.}

The 300 WSM is NOT belted witch makes it very reloader friendly when compared to the belted mags.

The shorter powder collumn and the over all shape of the case should make it an inherintaly more accurate round.(If at is actually needed for the type of game that this round was meant for or if the average hunter would be able to take advantage of this minimal gain in accuracy will be debated till the end of time.) I for one am much more confident in an extremely accurate firearm,to the point that I will never hunt with a rifle that is not more capable than I am!

That being said I have yet to own a Short Mag but have owned a 300 Win. Mag. in Savage 116 configaration that put much meat in the freezer. I see absolutely no reason not to have the more "user friendly" version.

Buddy of mine bought one and it would stack groups all day long.  It was enough to get me wanting one.  His didn't have a BOSS but recoil wasn't too bad; about the same as a regular 300 mag.  I ended up buying the 270 WSM and love the rifle and less recoil.

[Zachary]

Perhaps I should have mentioned that I own one.  It's a Winchester M70 Classic Stainless with a 24" barrel.

I say that it's ballistically identical because, when using 180 grain Power Points, it shoots in the exact same place on the targets at both 100 and 200 yards.  Accuracy was about the same - sub 1" groups.

Yes, I would say that the WSM kicks a little less than the WM.

my friend has one ,he says that you can`not use longer bullets when reloading,and are limited in bullet choices???

[acearch72]

Zachery,

I have a friend that has a Winchester Model 70 in 300 WSM.  His is the Walmart version.  I personally shot the gun and it didn't come close to 1" MOA with the winchester 150 gr. silvertips that he was shooting.

Wonder if the Walmart special is different from the standard 70 with respects to accuracy or the 150 gr. just didn't shoot well in this gun??

[Zachary]

jdt,

It is true that heavier bullets, which are thus generally longer, are not really suitable for the WSM because of case capacity.  A 180 grain SST, for example, would intrude into the case much more than a 180 grain Power Point, or any other bullet of equal or lesser weight for that matter.  I was using the 180 PPs and they shot great.  I don't reload yet, but when I do, I would use 165 grain Barnes X-BT or Nosler Accubond, or SST Inter-Bond - which would be almost as long as the 180 PPs.


ace,

I don't know about the Wal-Mart Specials.   I can only imagine that certain guns shoot certain groups better.  I can say that I am strongly against lubed/coated bullets.  I have heard horror stories about moly.  Tell your friend to try and use other bullets like the 180 PPs, or other loads by Federal like the Trophy Bonded Bear Claw or Grand Slam.  More and more companies are making factory loads for the 300 WSM.

A friend of mine bought a Win FW Classic 300WSM this fall and we have been shooting it a lot.  Its a great rifle and the accuracy is well within what I call an acceptable big game hunting rifle.  I then had the opportunity to use it on an late season elk hunt this past month in  UT. We had four tags and took two elk with this gun and the results on broadside hits were good using 180 grain Nosler partitions.   Both shots which were at around 200 yards  passed through the elk and the elk were down within 30 yards.  I do not see much difference in the 300WM and the 300WSM in performance.  Obvious advantages are more efficient use of powder and short throw action if that is important for you.   I was real hot on this at first but I am not sure I am now.   I guess it all depends on what you are looking for.  I am not sure what I would buy if I was looking for a 300.  I shoot a Pre 64 MDL 70 in 300HH and would not buy either of these two to replace it.  The differences are just not enough to excite me.  My next gun will be a 338-06.  Don't ask me why I am still trying to find a reason so I can explain to my wife why I need another gun.

[Zachary]

Tracker,

Why would you have to explain anything regarding your hobby to your wife anyway?   Maybe it's a married thing?

I guess I'm glad I already own about 14 rifles, 8 shotguns, and 4 pistols. :grin:

after much research i decided not to go with this cartridge.i was looking at a browning a bolt.the short barrel on this rifle make it about the same as a 30-06,plus i'm hearing too many rumors about longer bullets taking up too much space for powder.i'll stick with the .300 winny mag,since i know what it will do!  :wink:

Right on jiminpa!   Many of these short mags are coming in 22" barrels which diminishes  their ballistics below the full length counterparts. Heck put a 26" barrel on your .30/06 and you get into the .300 WSMs backyard with a 22" barrel :lol:

I bought one of the Wally world versions of the WSM in 7mm it is a Win Mod 70 Super Shadow.  Up front I never have liked any Belted Magnum cartridge, Just a personal thing.  Just like some like Ford or Chey but will not have in the driveway vehicle of a particular manufacture.

I am an avid reloader and shooter I also had to have my right shoulder rebuilt after a car accident about 8 years ago.  Hence I don't like a lot of recoil!!  

I bought the 7 for a couple of reasons one of which is I have 4 different handguns in 7mm and I like the caliber as well as the variety of bullet weights avaivable in it from 100 grain to 175 grain.  

In Accuracy, my son and I went to the local range and while he shot I spotted, he was able to put 3 shots at 110 yards center to center .470 of an inch. I routinly can put 3 shots in under an inch and it dosen't seem to matter what charge or bullet I use.

Recoil is not nearly as bad as I thought it would be, Win did something right with this gun it actually has a recoil pad that works!  I haven't had the chance to do a lot of work with the rifle or cartridge or rifle yet but what I've seen I really like.  I figure that with up to a 150 or 160 grain bullet chosen properly I will be able to reliably take anything I choose to.  Actual velocity I don't know as I have not take the chronograph to the range with me yet.  When the weather gets better I will.  The gun is a lot of fun and I'm looking forward to what I can do with it.  I've already got low velocity load data from Accurate arms for goofing off with lead cast bullets as well as data on some really top end loads.

If I only had 26 guns I probably wouldn't have to explain anything.  Problem is I have 32 Pre 64 model 70's alone. I keep telling her it's an investment thing.  And to be honest in 28 years of marrige never once had to ask for permission or justify why I made a gun purchase.  When you buy jewlery on those special days you keep em happy.
