Have any of you guys compared the peformance of the .300 WSM to the .300 Win Mag in practical, hands-on situations?

Regards,
Jon

nah, gave up any interest in bolt actions long ago, along with any interest in stuff more powerful than 308. wouldn't bother with 308,if not for really cheap milsurp ammo, and 7 lb alloy framed BAR. For certain "sport hunting" uses,such a gun would be nice, albeit unnecessary for any practical purposes.

I would love to hear from someone who has an AR-10 with one of the .270WSM or .300WSM, etc., uppers on it. Sounds like a neat gun with some longer range hog hunting applications!

The .243 WSSM is capable of sub-minute accuracy in a 6 1/4 pound rifle with factory ammo. The real asset of these shorty cartridges is their accuracy.

If the other WSSM and WSM cartridges are that good, then the .300 WSM should be a winner.

since hog hunting is typically done with dogs, with the shooting done at 50 FEET or so, I fail to see your point. :)



Since theres ZERO need of anything LIKE 1 MOA accuracy for big game, or even coyote sized varmints, and no NEED to take small varmints at long range, what's the point of sub-MOA 243,hmm? There aint any. It's all some bs that gunwriters have managed to stuff into your pointy little head, that's all. SMALL deer's chest circle is 8", and 243 sure AINT humane on deer beyond 400m, cause it won't still reliably expand a sp out there, and because it's down to .45 ACP type "power" levels out there, too. 8" at 400 yds is just TWO MOA. :) Also, of course, there's target MOVEMENT, wind, mirage, and a host of other factors, all of which call for a 300 Win mag and a BAR for such shots, not a bolt action 243.

then when you just WOUND the critter the 2--3x greater power of the 300 win mag MIGHT slow it down enough to let the gas op, BOSS comped BAR get in a finishing hit.

I'm keeping my eye on the .300 WSM, I have a 6.5X.284 "over the course" rifle built on a McMillian stock, Jewel trigger, tuned pre-64 Win action that the barrel is about tits up, the throat kind of looks like an alligators back though my 40X bore scope. It's barrel time soon and the .300 WSM is high on the list.

You know if you loaded the .300 WSM to hot .30-06 levels you would still have a very good long range rifle. The .30-06 case will run 190's right to 2850 with no problems at all and it's quite superior to to 175's in the .308, without the short barrel life of the .300 Win Mag.

Now Teufelhund knows what he is talking about. On the other hand, gunkid hasn't a clue. How can he say anything about the WSM if he gave up bolts long ago.

Does Leupold offer a Mark IV BDC cam for the .300 WSM yet?

nobody says you have to shoot the 300 a lot, much less with full power loads. That's just your fantasy. slowfire bs is so easy, VERY little practice has to be done in order to be just as good at it as anyone else is (under practical field conditions).

Put a GOOD can on that 300 BAR, and it is TAMER than an uncanned 223 is. :) It becomes DEAD rock easy to hit men with it at 1/4 mile, andmuch beyond that range, EVERYBODY misses quite a bit, under realistic conditions. People MOVE, wind suddenly lulls, gusts, changes directions, etc, and you MISS, that's all.

Of COURSE old YS hasn't done any comparisons. He's neither owned nor fired anything in years and years. Right, YS?

Actually, my head is big and round.

GB - How do the exterior ballistics of the .300 WSM compare with the .300 Win? How close?

Jon, if they shoot the same bullet, the ballistics will be almost the same. The WSM and WSSM shorty cartridges have all been designed to replicate the velocity/energy of popular cartridges.

IMO, the advantage to the shorties is accuracy, and to some extent, efficiency.

The downside to shorties are the bulk and feeding. Being shorter means that the WSM's and WSSM's have to be fatter. As a consequence fewer shorties will fit in a magazine and they don't feed as smoothly as do conventional cartridges.

You saw what my WSSM did. I like these cartridges.

That's what I was after, GB. As you may have guessed, I'm working, formally now, toward a new long-range rifle. My .300 that you saw is on its second barrel, and while I still enjoy and use it, I would like to try the WSM. No point in building that on a long action, so ... Was just curious if, an a very macro sense, I could expect performance of the .300 WSM to be close enough to my .300 Win ballistics out past 600 yards that the .300 cam for my Leupold M3 would still get me on paper. Under 600 is not going to be a big deal I don't imagine.

Yes. I would not even consider taping antlers on my head and walking through any of my fields in which you and that little rifle are standing guard.

Regards to you and Eurochick - oh, and again, congratulations to her on her completion of her masters.

Best regards,
Jon

... there's an outfit (I will post thier address, I have to find it) that will make "cams" for anything for the MK4 M3 or LR M3, you just send them the specifics.
Teuf - Are these the guys you referred to: http://www.kentonindustries.com ?

Best,
Jon

Jon, if you would like, I can calculate the trajectory of your favorite .300 WSM load relative to the Leupold cam setting. That way you will know if the bullet will hit high or low at a given distance and by how much.

Temperature, altitude, barrel length, ammo brand, and similar stuff is probably a lot more important than any difference between the .300 WinMag and the .300 WSM.
