I'm in the process of buying a rifle one of the two above mentioned, the 7mm stw or the 300 wsm. I lean toward the 300 short because I'm a short cartridge fan. But, I've seen the 7mm stw in action, it's a hunting machine. So, with no further adew give me your thoughts. Price will have some reflection on choice, I've found a 7mm for a pretty fair price at this point, but not the 300. I should add, the Win mod. 70 LT is my choice of manufacture at this point. thanks.

Both of them are accurate the 300wsm wont eat your barrel as fast as the 7mm STW my choice would be 300wsm all the way. 7mm Rem Mag would be a better choice in a Sendero Sf rig if you had the $1200 bux to put it together. IMHO sad to waste a barrel on the 7mm stw when the 7mm rem mag are the same as for handloading you can reach the Stw performance with the 7mm rem mag.

As for recoil the 7mm rem mag is hands down more pleasant to shoot follow up shots wont wear your barrel out as soon as the Stw either thats my opinion its really up to you.

I'm not saying this is the compete info on the two cartridges one way or the other, but here is something you may want to take into consideration.

If you look at Winchester's website, you'll notice that the 7mm STW factory ammo won't push a 140gr bullet any faster than a 300WSM will a 150gr. When you get into the heavier bullets, it's not even close, and the BC of the 180gr .308 bullets will rival anything the 7mm has to offer in factory available rounds that have bullets that can be considered useful for hunting.

If you want to drag a heavy rifle with a 28" barrel around to get the performance that the 7mmSTW CAN offer, more power to you, but that is what you'll have to do to realize the true power the cartridge can produce. The 300 WSM in equal rifles with a 24", or shorter, barrel will offer equal or greater performance at all ranges with all bullet weights when using factory ammo. The difference is pretty much academic between the two in standard sized rifles with factory ammo, so I'd let the rifle be the determining factor. Personally, I'd take the .300 WSM for the more compact rifle and lesser muzzle blast. I think the 180gr factory loads would be a better choice for large game than the lighter 7mm bullets that are offered. I'm sure either would work well one way or the other, it's up to you.

Well, I have to admit, my mind was made up when the cartridge first came out. I'm a fan of short fat cartridges!! But,I've seen what the 7 stw can do, I was impressed. I also like long barrels. The 30 cal bullet is a good one and, lots of different types. So the 300 swm was a given. I appreciate your replys and the time you took to answer thanks. From what I understand, I got the last one in stock at the place my friend deals with. Must have been made for me.ARC LITE :D

I certainly cannot advise anyone to get the 7mm STW. If you want a fast 7mm, then go the Ultra. My 7mm STW uses about 7 gr. more powder to just barely beat (75 fps) the 7mm Rem. mag. What it supposedly did as a wildcat did not hold true when it was put under pressure restrictions. From what I can see, the 7mm Ultra is what the 7mm STW wanted to be, but isn't. It's just not what it cracked up to be IMO.

Want to have some real fun? Check out the .300 Remington Short Ultra Mag. in the Armalite AR-10 (T) Ultra. If you can stand the 10.5 pounds of weight sans scope and empty, you will have one heck of a tack driver. I wonder what that thing will weigh with a decent scope and a mag full of .300 RSUM? I can almost assure you that you won't see one of these at the range every day!

to bad you didn't look at the 7mm ultra mag. with 93.5 grs of h1000 i'm pushing a 140gr barnes coated bullet 3685 fps with 4220 fp. and the 700 bdl didn't break the bank. i can't say that about my shoulder though. on bags at the range i covered a three shot group at a hundred yards with a dime. no bull.

Just got back from shooting up a box of 150 grain Winchester Supreme 300 WSM in a Winchester Model 70 Super Shadow.

Was pleasantly surprised. The rifle/ammo grouped ~7/8" @ 100 yards. Also shot at 200 yds and 300 yds with results as expected. I'm thinking group size should shrink if I can find a good reload (if I can get time to reload). Figure I need more practice, though.

One other thing, Winchester is touting the recoil pad on this rifle as being something special. Don't know how special it is, but it does it's job very well. Felt recoil wasn't bad. A friend had a 30.06 Ruger, and said he couldn't really tell the difference in how the guns kicked even though muzzle rise was substantially more with the Winchester than the Ruger.
