ok so I need some opinions on ballistics for 3 loads.
1)7mm WSM, 2)7mm STW, 3)270 WSM

I am looking to buy another rifle and have narrowed my search to one of these. It will be in a bolt action or possibly a Thompson Encore rifle. I originally thought I wanted the STW for its little extra over the 7REM Mag. but found some ballistics in my research that suggested the 270 WSM had similar or better ballistics than the 7 STW.
I was hoping for some personal experience and insight from you guys on these. I am still researching on my own, but thought I'd post here in the mean time.

My neighbor has gotten me into reloading so the availability of ammuntiion isn't an issue such as with the 7 STW.

Re: 7WSM? 7mmSTW?270WSM?

What do you plan to use the rifle for? Are you interested in longe range capable, high BC match bullets, or stoutly constructed hunting bullets like A-Frames, Barnes X, ect... ?

The 7wsm will win just about every category, with the exception of ultra long range shooting, where the 7STW will of course edge it out slightly... same bullets, more powder/capacity, no disputing that. But you'd have to get a long way out to see the benefit, I'd say 1000-1200yds plus. This is of course at a steep cost of heavy recoil and muzzle blast, short barrel life, and increased reloading cost.

The .270wsm has absolutely nothing on the 7wsm that I can think of unless you already have a large supply of .277 bullets or something like that. The slightly shorter neck of the 7wsm is a very slight detriment, but for all the benefits of the .284 caliber that seems like a small issue.

Just my $0.02

The STW is fast, hard recoiling round that is hell on barrels. If I was going to shoot it often, I would avoid the STW, having said that, it is a devastating hunting round, that most would fire 10-20 times a year. JMHO

thanks this is what I was after. I haven't had the chance to shoot them myself. Basically it will be used all around and I tend to prefer smaller calibers. I have a .223 and a .243 that I like both. The 243 is great for whitetail, coyotes, etc. but wanted something with alittle more range and energy for larger game. Most of my shots are taken at 500-600 yards max, but with some practice would like to be able to shoot up closer to 800yards. sounds like the 7WSM should do nicely for that.
I was leaning towards the 7WSM anyway, but was comparing ballistics on remingtons site and it claims the 270WSM using 150gr bullets was actually out shooting the 7 STW, like 300lbs more energy and an inch or so less drop at 500yards. Granted it was a 10gr heavier bullet, but still yet. I found that a bit hard to believe but also didn't know how much of an improvement the short mags made.

for those who have personal experience with 7WSM, what kind of ballistics are you seeing with them at longer ranges. say 800+ yards. How does the STW compare to the regular 7mm Rem. Mag?

Re: 7WSM? 7mmSTW?270WSM?

Forrest I can tell you the STW does not compare at all with the 7mag. STW is far superior to the mag. I have owned both and still use the STW.

I have no experience with the 7wsm so I cannot comment, the users here who have really tested the 7wsm have gotten outstanding results.

I hunt with the STW and it is an awsome round for that purpose!!!

Re: 7WSM? 7mmSTW?270WSM?

Are you looking to have a rifle built, or buy something from the factory?

You might want to check what's offered in the rifle you want, or what rifles are offered in the caliber you want.

I don't see any TC Encores in WSM calibers or 7 STW. Remington doesn't offer anything in 7mm WSM or 7 STW either. Remington does offer several models in 270 WSM though...

Re: 7WSM? 7mmSTW?270WSM?

well I am not set on Thompson or really set as far as brand, I just really like the Thompsons. I will end up buying either factory or used. I cannot afford custom. Basically if I do not like the feel of a rifle I can change stocks or have alittle work done to it. but I cannot easily change the load it shoots, so that is how I am basing my search on caliber.
The WSM calibers are offered in various models of different brands. Browning, Remington, Winchester and Savage. The 7 STW will have to be a used version or possibly take a 7 Rem Mag and have it bored out to the STW. I have seen that done once, although it took 2 trys on a TC Encore barrel due to the first being messed up and then being forced to bore it on out to a 7 Ultra mag.

I guess my thing that makes me leery of the STW is the fact that I have never shot one. I have only heard of others that have and like it. Whatever I buy I intend to keep for all around use for quite sometime. Add a nicer barrel etc as funds permit.

The STW fries barrels.
The 7 WSM and 7 SAUM may not be around for long
You want good performance, reasonable barrel life and good resale value, you will buy a 7mm RemMag. There isn't an animal living in the lower 48 that won't die right now to a 7mm RemMag. Should you need it there is a TON of factory ammo available as well.
Of course, dare I mention the 7x57?
Accurate, wide bullet selection and far less blast, recoil and roar than any of the magnums. Bell did pretty well with one.........

Re: 7WSM? 7mmSTW?270WSM?

The Saum may not be here forever, but I think the WSM is here to stay. Remmy was slipping on this one. I like the STW for hunting and ballistics are unreal, but barrel life is not conducive to punching paper, and is expensive as hell to shoot.

Re: 7WSM? 7mmSTW?270WSM?

Check out T/C Encore Rifle site. You will not find any calibers that have spike,high pressue,i.e. Rums STW's Ultra's. Corret me if I'm wrong. The ballastic differences between a .300 WSM and a regular .300 WM at peak tractory is only one inche. Yes,the.300 WSM does it with less powder,but I don't stay awake at night thinking about it. .300 Wm options are abuntant and pretty well laid out,well proved. If you want to put a couple thousands rounds down the tube,I suggest the .308 caliber.

Re: 7WSM? 7mmSTW?270WSM?

From my experience,

If you want a mag for hunting and shooting to 800 yds, I'd go with 7WSM or 7RM. The STW is good but harder to shoot well for me because recoil and the throat shows wear at a quicker rate.

I have several 1000 rounds down my 7RM and have not changed my bullet seating depth yet. You really don't need huge horse power to reach 800 yds but you need to be able to shoot accurately to hit deer or coyotes to the ranges you mentioned.

Re: 7WSM? 7mmSTW?270WSM?

Ok thanks guys. You have answered my questions. I am going to avoid the 7 STW. The reason I really like my 243 is because of the lower recoil, and its faster to follow up on shots for this reason. I like the 7WSM and thinking I will probably go this route, although if I find a rifle I really like in 7mag, I won't turn it down. I had a Savage7mag a few years ago and wish I hadn't parted with it. but maybe this will be my chance to try one of the new short mags. if I do not like it I do not think it will be hard to sell.
again thanks a bunch.

I am going to have to put this rifle thing on hold for a bit now. My brother just got layed off. he has helped me alot in tough times and returning the favor is more important right now. Just wanted to say I appreciate the help guys, and will post up when I do buy one. but for now.....priorities.

Re: 7WSM? 7mmSTW?270WSM?

How many shots does one average from a 7mm STW barrel I have a Sako 75 with around 100 shots down the tube......am I looking at 1000 or so rounds ??

Game i have hit with it has gone down pretty hard. I shoot 154 gr Interbonds from it.

Re: 7WSM? 7mmSTW?270WSM?

For when you come back to this thread, I am going to cast my vote for the 7WSM as well.

Last year I spent several weeks analyzing calibers in regards to barrel life, accuracy, bullet selection, and external ballistics. I wanted something in a short action that could beat the .308 hands down when it came to external and terminal ballistics. Did not want to give much of anything away to the long action magnums though.

7WSM kept looking better and better so in went the order for a custom 7WSM to be built, and it should be almost done now...

Re: 7WSM? 7mmSTW?270WSM?

Kyreloader......I am using 82gr of H1000 and my chrono speeds are average 3152 fps a bit slow for a 7mm stw I feel but the load shoots alright. On Larger thin skinned animals (shot probably 20 head of game with the gun) I am getting pin holes so far, a few animals I did not inspect.

It seem I will be taking this rifle away pig shooting in April this year, there is some feral horses there as well so I wil lsee how the interbond behaves on those.

Last trip up we shot feral horses with our .416 Rigby's and .585 Nyati's and they put them down with authority !!

This year I was planning to take my accumark 338/378 weatherby mag but that rifle is getting sold for a .338 LM built on a Surgeon Action (you guys on the hide have changed my taste in rifles) so it might be sold by April. If I had my surgeon .338 LM thats the gun I would take for sure !!

I agree about the 7 wsm.
the 270 and 300 wsm are outselling it a bunch.
I also am a fan of the 7x57 everyone overlooks this one very much plus the 6.5x55.

Same here.

And who cares if they drop it as a factory round? All you have to do is neck size some 300wsm Norma brass and fireform. Now if we could get Lapua to make some wsm brass we'd be set.
