270wsm...what gives!!!

[j_22250]

why is this site not talking more about the 270wsm? ballisticly isn't it the better cartride over 7wsm and 300wsm.,given that people are shooting 110-150gr. bullets in all three cartridges).

is bullet selection the only thing holding this caliber back? most people on this site reload anyways so that should only be a problem for people that shoot factory ammo. why are the ballistcs of 7wsm always slightly better with same bullets..... ahhh@$#$!!! what the hell...why? isn't the 270 bullet the one with the higher bc and sd and shouldn't it be the one to always come out on top given same velocity?

most of these questions are jst me going off and not me asking actuall questions; cuz i think i already know the answers.

if your looking for something in between .264 and .284 the .277 is perfect and who needs a huge bullet choice...heck i can't make up my mind anyways so K.I.S.S. the bullet choice for .270 is pretty good. berger and sierra have match bullets avaliable and nosler bt's would be good too....but then on the other hand, if they ever come out with .264wsm then i'll be one of the first to trade off my 270wsm an get in line.

bullet selection is poor compared to .284 and .264

I went with the 270wsm as i got a good deal on a sako 85 and just wanted rid of my 7mag,remington) after having 2 remmies i Just dislike that i needed to get shot of it! and never felt good about shooting it. Looked into the ballistics etc and the 270wsm was on par, infact shooting 150gr bullets the 270wsm was ballisticaly better than my 7mag was shooting 150's

It looks such a good cal just a shame that you cant get more bullets in the 150-160 range! a decent target bullet would be nice. hunting wise theres a fairly good choice of 150's.

Could be for the same reason as 25 caliber. Ever hear any but a few talk about the 250 Savage, 257 Roberts, and for that matter, the 25-06? Had a Krieger barreled 250 Savage built a few years ago, and like the 270 caliber, bullet selection was minimal, at best.

 

[PestShooter]

Crappy bullet selection. I am shooting 150g Berger VLDs in my .270WSM and I love the .270WSM.

 

[Jeffvn]

Yep, crappy bullet selection. Compared with the 7WSM shooting the 180 Berger, the 150 Berger for the 270 WSM is left in the dust. If Berger ever comes out with a 170-175 grain VLD for the 270, then you might have something.

if i had it to do over i'd proly get a 7wsm and shoot 168gr bullets. 180gr. bullets are on the heavy side for a 7mm and would be the equivlent proly of shooting 168 out of the 270. the 140's are ideal in the 270 and i would rather shoot them out of a 270 than 7mm or 150's in a .30 cal. many of you won't argue with me there. now a 142smk in a .264wsm now that would be a screamer.,i don't know why i favor the heaviest bullets in the .264cal; i guess cuz with the case capacity of wsm i can see justifying it). i would shoot 180's outta something like a 7mm STW, 7mm ultra mag, weatherby mag or maybe even something bigger.

i jst realized the whole argument about poor bullet selection. IT'S NOT TRUE and gives the .270 a bad rep especially with alot of newcomers,etc. even i had it out for the 270 and poor bullet selection, but now that i'm givin it a shot i finally realized.

it's actually the poor selection in bullet weights; for all those out there who are either looking to be different, looking for the next big thing or want to have the biggest baddest there is and like dropping lots of cash on jst one rifle.,btw, i jst so happen to be one of those guys)

bullet selection is great if you want to shoot a 270. after looking at the 7mm info page the bullet selection is no better for 270 than it is for 7mm; jst choices in bullet weight from 120 or less all the way up to 180.

then again i don't guess i've ever seen too many choice in different twist rates for the 270. why change something that works i guess.

The 7wsm also has slightly larger powder capacity than the 270wsm. They shortened the neck and made the case body longer. :crazy:

 

[NRV]

Shhhhh... If everybody knew how great a 270 WSM is, none of us that have one and love it would be able to find .277 bullets available. It's hard to beat for a hunting round.

I have a Browning Eclipse in 270WSM that I haven't shot alot, and am still working up loads for. The 26' barrel should help the ballistics slightly, but I agree there is a need for higher BC bullets. If we could get Lapua or Berger to make a 160gr with a BC in the .600 range, we'd be in business.

I'm having a 6mm built in a wildcat based on a RSAUM cartridge, and ran into the same problem there. I have a decent selection of hunting bullets, but the target bullets fall considerably short of the .600 BC range. As a result, this gun will probably be limited to use out to 600 - 700 yds on still days. It is designed as a hunting rifle anyway and will weigh in just under 7 lbs. Not exactly 1K material.

NOW, I've been considering creating a new wildcat by necking down a Dakota cartridge. The .277 diameter would be an ideal concept, since there is only a .007' diameter neck reduction, and the .270 bore is generally at the bottom of most hunter's range of calibers to hunt large deer, such as elk, moose, and caribou. This round would be capable of surpassing the 270 Weatherby, without all that free-bore. Only problem is that the cartridge would be capable of outperforming available bullet selection. This caliber would be more than capable of pushing a 160gr long-nosed bullet about as fast as you'd care to have it pushed. Recoil would likely be milder than the 7mms or 30s, too. This might be a good 'speculator' cartridge to build for those of us wanting to dump a large amount of cash into 'the next best thing.' I like that comment, 22250!

I didn't mean to hi-jack this thread to talk about my personal projects, and I'm still working with the 270WSM. I've threatened to sell it to pay for my other projects, have it rebarreled to a .264 WSM, etc. Actually, I think I'll keep it just as it is and find some good loads for it! I will agree, the .270 bore is about as near a perfect hunting caliber as you could hope for! Cheers, Mr. O'connor,Jack, that is)... you are an inspiration to us all!

 

[jraney]

other than poor bullet selection is there any other reasons why i should not get a .270wsm?

 

[4bycamper]

It's hard to beat the 270 WSM for medium to medium-large game.
My newest loading really blasts the 150 AB into MAGNUM land.
Using 70.3 Magnum powder and a CCI-200, my Chrony says 3155 FPS,average). And accuracy is outstanding for a hunting rifle.

Previously I was using H1000 for 2960 FPS. Since Ramshot powder has become hard to find, I'll be trying Retumbo to duplicate these efforts.

I JUST PUT A 30 INCH HART BARREL IN 270WSM ON MY 700.1ST WE TRIED 110 SIERRA PRO HUNTERS IT DIDN'T LIKE THEM. THEN TRIED 130 SIERRA PRO HUNTERS AND 3 HOLES TOUCHING AT 100 YARDS. NEXT TIME WE WILL TRY 400 YARDS HOPEFULLY BEFORE OPENING WEEKEND.

Friday I had a Tikka Lite stainless/synthetic in .270 WSM in my hands at a local gunshop. This cartridge has a rep in southern Ontario for being the most accurate of the WSMs. But the thoughts of magnum recoil in that light rifle made me wince. The heart was willing but the brain said no. So I am going with the 6.5x55 in the Tikka instead. But I was thinking of this thread while I was handling the .270 WSM.

 

[j_22250]

switching to standard primers seemed to take some of the recoil out of mine and get tighter groups. only problem now is i have some cratered primers with 65grs. of h4831sc.

what happend to the old dirty thurdy for deer killing?

A friend of mine has had a reamer cut by Pacific for a 6.5/270wsm of his own design. He is developing a rifle for F Class that he thinks will be a winner next Summer on the Canadian Army ranges.

So your beloved .270WSM may become the proud parent of a 1000 yard target winner. Time will tell.

 

[j_22250]

here's a pic of last target i shot at. i shot 8times and this was jst a rough sight in to test standard primers. it was raining and i jst wanted to get it close enough to where i would be able to hit something with it. first one hit either way high or low. i can't remember. the two shots that are more spread apart were next and the next two were a little closer togeter. a couple of clicks left and that's where the last three landed. the last three measured .418'. not bad given the conditions. i need to go back out and soon, deer season is jst around the corner.

 

[j_22250]

got a chance to go back out with the ol 270wsm. i thought that i had my load and so i loaded up 50 rounds of ammo with standard primers. my initial load development had been with mag primmers so i figured i would have no probs. with standards. well i guess the cups aren't as hard so i have gotten cratering on all, but no flattening. no big deal right; well 25 of 50 so far and i've had two split necks and 1 sticky extraction. TOO HOTT!!! so i'm gonna try 1 less grain and see what it does. i'm dead on at 100 and can hold dead on out to 200 easy only dropping about 2". 6" at 300 and 20" at 400. that's pretty flat. my groups opened up a bit, but still under 1moa. i'm guessing it's cuz my barrel wasnt' spotless. proly around 25 rnds thru it befor shooting this last time. plus the 16 i shot thru it today. cleaned it and i hope to try it out again soon. still kind of new to this round, but shooting once and only neck sizing the second time my cases were a tight fit. should i be fl sizing every time for this round? next batch will be the 3rd time and i did fl size those so we'll see what happens.


btw, i still dont own a chrony, but after running some figures over at JBM i figure i'm right at 3300fps. i'll be happy with 3150-3200fps if i can keep it shooting .5" and no signs of pressure. for those of you interested in getting one now, i would recommend a 7wsm. i hate to say it, but it's jst a tad bit better. it will beat out a 270wsm even with same powder charge and bullet weights.

The 7mmWSM has developed a positive reputation for a reason. This is not to say the .270 version is not a good round but collectively, there has been much more research and development in the last 30 years dedicated to 7mm bullets and barrels than to .277. High quality bullets and barrels are just so much more available in 7mm so unless one wants to "trail blaze", the 7mmWSM is just easier and more likely to end in success.

This comment may draw criticism, but it is my opinion that the .277 is headed more towards being a 'dead' caliber than a growing one. The .270 Winchester is still likely to be the most popular in the caliber and it is generally considered to be a hunting only round. Do not look for it to become more popular with time considering the number of marketed alternatives. Rhetorically speaking, why build a .270 if you can build a .280, a 6.5x55, or a .30-06? The same can be said for the .270WSM when the 7mmWSM, 6.5-284, and .300WSM are available.

Do not get me wrong. I think the 8mm Mauser is a great round for many purposes, have a virgin 6.5mm-300WSM barrel I will probably never shoot, and these two rounds will likely never, ever be popular in this hemisphere. There are places where guys do not let friends shoot .270s though. ;D

THE 135 GRAIN BULLET IS THE BEST IN 270 WSM
