I cant make my mind up which is the better caliber,what ever I choose will be built by Neskia bay,I want a rifle that shoots flat and is capable of knocking most things over (Iam from the UK but do travel abroad)
he veiws for or against please

Go with a 300WSM!!

Im not sure why, but the 7mm WSM doesnt seem to be doing as well as the 270 or 300. I think it would be an excellent chambering. For a smaller caliber I would gravitate towards a smaller case as the WSM doesnt offer much beyond what a 270 Win will do, and the smaller yet you go in diameter the more truth there is to that.

Just my .02 C.

There is no (practical) ballistic performance difference between the two. The 7mm WSM does have a slight advantage in case volume as the shoulder was moved forward to preclude chambering in an oversized 270 WSM chamber. There is of course a (very) slight advantage (for the 7mm WSM) in bore cross section, but that is "splitting hairs". The 7MM WSM will have about a 100fps advantage over the 270 WSM with the same weight or perhaps a slightly heavier bullet.

That having been said the 7mm WSM has a vast advantage in bullet selection, and therefore versitility.

The only reason for the 270 WSM is the corporate desire to capitalize on the popularity of the 270 Win., and it has worked tremendously.

If you are a reloader and want the most versatility from the WSM chambering, the 7mm WSM is the hands down winner.

with the 7mm WSM what barrel length is reccomended,I would like something around the 22/23 inch mark as the rifle will be used for hill stlking so I wamt something farly light and pointable

FoxShooter, I have all 3 of the WSM's. I really like them all. If you travel I think that between the two the 270WSM would be the more practical choice simply because it is more popular and you are more likely to find ammo and components for it in different locals.
Most of my WSM's have 24" barrels and I wouldn't want to go less than 23 to keep the velocities in the neighborhood you want. Remember that you do gain a little shortness by going with the shorter action. A 24" barrelled WSM is about the same overall as a 23" std rifle. Here is a picture of my 270 Winchester Berretta Mato and my Kimber 8400 270 WSM both with 24" Barrels:



If you get a chance check out on of the Kimber 8400's. I think that you would enjoy one in whichever WSM you decide on........DJ

I have a Savagem16 Stainless synthetic in .270WSM and i love it (now i put a recoil pad on it). Very versitile caliber if u ask me. The 7mmWSM has lots of advantages but i just like a .277 cal rifle just my opinion. And yeah your more likely to find ammo for the .270WSM or .300WSM.

Foxshooter,

Tell us more about your planned rifle. A Nesika is not a run of the mill action! How much will it weigh and what will the stock be like? Who will make the barrel. Is it a single shot or repeater? Come on and fess up.

Keep in mind that a inch of barrel weighs one ounce. That's not much.

I have both the 270 and 7mm WSM and they are about the same. We don't know if you handload or not? If you don't the 270 WSM or 300 WSM are the best choices.

7mm WSM cases are easily formed from 300 WSM brass as long as one leaves a false shoulder to headspace on. That would be a bit of a bother, but if one reloads, it would be done @ home, and cases would probably not be an issue. As for the rest of the components being "hard to find" (my quotes) As long as you had cases, 284 bullets are probably one of the most common, possibly more choices than 308. Powder and primers are not any different for the 7mm variety.

I already have a Neskia rifle in 243 AI(light hunter) its so good I want another and yes Iam avery very keen hand loader
The rifle I will have built will have a kreiger barrel and be a repeater(magazine)

Since all the WSM's shoot well if you would conceed by definition. Then it comes down to your feelings about big bullets vrs smaller bullets. This is the area of such interest that keeps us all going.

Since I have some WSM's and other, older 300 magnums I would sellect from either the 270 WSM or the 300 WSM. Unless the ranges were maximum or dangerous game were on the ticket I would go with the lower kicking 270 WSM.

There are premium bullets in most all calibers now so any of them will penetrate well.

What is your stock like?

my stock is great its made by a company in Canada Robinson Composites the light hunter stock is only available through Nesika as its there own design,it has a very high monty carlo type cheek peice which lifts just right to posistion your eye to the scope which I think is very important

Is your suppressor threaded, or is there some kind of bilock device for attachment?

HIGHJACK!!!! HIGHJACK!!!! HIGHJACK!!!!

How is the .270 WSM's perceived recoil compared to, say a 7mm Remington Magnum and a standard .270 Winchester in equally weighted/sized rifles? I'm a BIG recoil wuss, but the LH Model 70 Featherweight in .270 WSM rather intrigues me. Thanks.

The 270 WSM comes back pretty quick with 130 and 140 gr bullets. The load I used last season was a 140 pushed buy 74.5 grs of MagPro and that made 3210 MV. The physics of it are all there. What you see's is what you gets.

On the other hand the new soft recoil pads help all guns but are easier to get on a new one as at least Kimber has them as standard.

I shot a M70 Classic a lot for a year in 7mm WSM that propelled the 140 at 3250. Again that one is no 243! The M70 came with a very hard pad that got replaced when the entire stock was changed. The new B&C stock had a good pad.

Those WSM's can be handled but one must be prepared.

Thanks for the reply. I had read a blurb in a recent issue of a gun rag, where a writer opined that the shorter powder column of the various SMs resulted in less perceived recoil. I wasn't sure if he was trying to say that the recoil impulse was spread out more, or if he was just blowing smoke.

I think the real theory goes something like this.

Recoil is based on the "ejecta" weight x velocity.

Even though the powder is burning and has been converted to a gas, it is still there (in mass ejecta weight) hence more recoil.

In other words if you are burning 10 more grains of powder in a 300 Winie to get the same velocity as a 300 Wusum with a 180gr bullet, the recoil (from the 300 Winnie) would be the same as increasing the bullet weight 10grs when comparing it to the 300 Wusum.

Simple physics?

The moderator is screw on and supported down thr barral by 2 "O" rings it make the rifle about 5 inch longer but the end result is well worth it,no muzzle flip,takes all the recoil out,you can see whats you have shot at,and it takes all the muzzlw blast out.
when fited to lets say a 30.06 it tames it diwn no end and makes it plesent to shoot.A muzzle brake will do the same thought of thiong but the noise in worse as it send it all out the side so you would not be very popular with your mate newt door on the range
dont anyone else use a sound moderator

We call them silencers here and they are legal in some states and not others for hunting.

Then there is the federal law regulating silencers. I am not positive on these details but one must submit an application to the BATF for one and pay a $200 fee.

The use of silencers has no critical mass here. Most of us think that we are not allowed them which is not 100% true.

I wish I could find someone to make one out of titainium I dont know why but over here in the UK they seem to be scared of using such material

They're legal to own in 36 states (Washington state allows ownership, but they cannot be installed or attached on a firearm). For individual ownership, there are two routes: A BATFE Form 1 or BATFE Form 4.

The BATFE Form 1 allows an individual to build one for his own personal use and the Form 4 allows an individual to purchase one from a dealer or manufacturer. Both application procedures are the same.

The forms are completed MINUS your signature and taken to the local chief law enforcement officer (CLEO), who can be a police chief, sheriff, district attorney, or district judge (there are a few others that have been allowed, such as highway patrol commanders, attorneys general, constables, etc.). The CLEO at his or her discretion, will sign the forms stating that they have no reason to believe you would commit a criminal act with the item you seek to build or purchase. You then sign the form, submit two passport photos, a set of fingerprint cards, a citizenship form, a check in the amount of $200 for the tax (you are actually applying to pay the tax for the item), and wait around 90 days for an FBI background check and approval of the transfer or approval to build. If the CLEO chooses not to sign your forms, you can incorporate and file to take possession of or build a silencer without getting a signature, or most of the other items listed.

As far as hunting with one, most states that also allow their ownership also restrict or outright ban their use in hunting activities. Oklahoma doesn't allow their use on game animals, but pests and vermin aren't considered game. Wyoming prohibits their use in the taking of wildlife, which on the surface would out and out prohibit their use for any type of hunting.

A suppressor is actually quite useful and polite, but there seems to be a stigma attached that only a hitman or a slightly unstable person would have the need to own one. They were included in the National Firearms Act of 1934 not because of any sensationalized crimes, but because there was a real fear that they would be exploited by poachers at a time when the government and conservation groups were genuinely worried about ever hunting deer or anything else again.

In Europe, they have socialized medicine, where they would rather not buy hearing aids if they can avoid it and denser populations. On a supersonic round, the sound signature isn't totally eliminated, just reduced to an acceptable level (reduced muzzle blast). Using a suppressor just makes sense.

There are a few manufacturers over here that use titanium, but most like aluminum.

anyone know of a company ir individual who can make a moderator out of alloy or titianium

Talk to Lee Minor http://www.lrmfirearms.com. Getting one made here is one thing, but exporting it might be another.

You might also try posting that question over at http://www.subguns.com in the NFA Discussion Forum. There are several manufacturers who participate in the discussions as well as some who are quite familiar with exporting NFA items.

foxshooter,
check out the NFA discussion forum at subguns.com. There are many that know a lot about suppressors (moderators) there.

I shot both my 270 WSM and 7mm WSM the other day and both did well. There is not much difference between them as far as bullet velocity goes with the lighter weights.

Keep in mind that the factory twists for the 7mm WSM are 9.5" or less and the 270 WSM is 10". This may make some difference between my ears I suppose. It's one reason that I am not going to liquidate my 7mm WSM should I want to shoot heavy bullets for some reason.

Also Norma and maybe others make 270 WSM brass not that it's better than the Winchester.

BINGO!

This supports my opinion that the 7mmWSM is probably a better choice for versitility.

The question of which is the better caliber is easy. Neither is better than the other. They are both great and it just comes down to personal preference on bullet choices. My personal choice would be the 7mm just for the bullet choices.
