so here is the question i searched and have found several replys on this and the majority of the answers ive found have all been people prefer bullets in the 130-140grain range. last year was my first year hunting with this gun i got it from my dad and he had not shot anything with it but had bought it early 2000's i geuss around the time they came out. when he got it about the only thing he could find was winchester ballistic silver tips in 150gr so that is what he shot i like the bst's so when i got the gun from him i was happy with that. i just recently got into reloading and will be loading for this rifle and have already purchased 150gr but im starting to wonder if 130's would have been enough. it doesn't seem like it can hurt anything slinging a bigger chunk of lead at a deer but what is the reasoning for the lighter bullets. that was part of the apeal to me was that i could shoot heavier bullets at pretty much the same speed as lighter bullets in the 270win.

This is the only reason I own any of my magnum rifles....to shoot heavier bullets faster than my standard chambering can.
For the record I like 140 Accubonds in my .270 WSM

Like Ted says, you've got the right idea, slinging heavier bullets faster. The lighter weight bullets will shoot flatter, meaning better tragectory for longer range shots.

Me, I like the middle of the road 140's. Berger VLD's mainly, tried the 140 Accubond on a doe last fall, liked the performance, wouldn't hesitate to use it on larger game.

I prefer the 140gr Accubonds for my reloads. The performance at the range and on big game here in Alberta has been impressive. So much that I had traded all the 140gr TSX's I had a couple years ago for more Accubonds. Elk, moose, black bears, whitetails and mulies. Most shots - 1 Shot kills, double lung complete pass through penetration with major internal damage. Reloads with speeds 3260-3300 ft/sec.

I you make the shot count, you will have your animal.

The 140gr TTSX's would be my next choice now but I'm going to stick with the Accubonds. Its all I use in my other big game calibers.

sks, first of all there is absolutely nothing wrong with shooting your 150's in a 270 WSM. The 'reasoning' behind the lighter bullets is that the original WCF 270 was designed from the get go as a flat shooter, and to many is the quintessential 'western' rifle due to it's flat trajectory and lethality, almost all of this established with 130gr bullets. The 270 WSM just takes this axiom to another level. I have shot 100 grain TSX's way out there at things like coyotes and antelopes, and it is just a damn laser beam for flat trajectory.

Today, 130 isn't near the lightest in 270 cal bullets that are readily available, 110 grain TSX are very popular, and very lethal, 90 and 100 grain bullets are very common too, although I feel under 100 grains is a varmint round for sure....have seen some incredible performance from 100 gr TSX's though, even on some good sized hogs.

The WSM with a 130 gr bullet makes a very flat shooter with excellent lethality, and I have personally taken some VERY big critters with that combo, at very long range. I tend to like mid weight for caliber bullets, but I really like the 140 gr Accubond in 270, both the standard WCF and the WSM.

You might think about developing a load or finding a factory cartridge with a 130 grainer for a flat shooting setup in case you go hunting for critters where a flat shooter would be an advantage...I bet you can find a load/ammo that will shoot great in both weights for you pretty easily, the 270 WSM has not been picky for me to load for.

Good shooting!

I shoot the 130 gr Nosler Ballistic Tips, 140 gr Accubonds and 140 gr Hornady SST's. For deer the 130 is more than adequate, anything bigger and the Accubond would be my choice.

My all time favorite load for the 270 WSM pairs a Nosler 140 grain Partition and a max load of RL 22 for a velocity of 3200 fps. I have shot coyotes, deer, and black bear with this load and have never been dissapointed.

However, due to stupid California law, I had to find a "no lead" load for this rifle. I tried 130 Barnes TSX and 130 Nosler E-Tips, but they just would not shoot as good as I liked. They shot alright, but not the tight groups I was used to with the 140 Partitions.

Just on a lark, I tried the 110 grain Tipped TSX over IMR 4350 and that load shot great groups. I am shooting that bullet at 3600 fps, it really shoots flat. I have not shot anything but coyotes and an antelope with this bullet as of yet, but it worked great on them.

I shoot a couple of .270 WSM's, both Model 70 Winchesters. For Deer sized game I shoot 130 grain Nosler Solidbase-North Fork-Nosler Partition-Barnes TSX. The Solidbase bullets (I found cosmetic blems from Nosler dirt cheap) do the plinking with the more expensive premiums loaded for animals. For game larger than Deer I use 140 grain Barnes TSX and 150 grain Nosler Partition and North Forks. The North Forks get the real serious hunting because of speed and accuracy. Good shooting.

ive got 100 150's to load up and that should last me quite a while i may later on down the road check out the 130's or 140's but the one whitetail i shot with the 150 at about 50yds peformed awsome. i was originally worried about pass throughs with little damage due to some of the things i had read but found that to be completely un-true. also i have 1 full box of factory loaded 150 ballistic silvertips and they have shot well from my rifle is there a way to find out what specs they are loaded to so that i can maybe duplicate them and save some time developing loads?

sks, you will be well served with your 150 grain NBT's. In fact at yardages that are closer--like 50 yards, I would much rather be shooting a 150 gr NBT than a lighter weight. The knock on Ballistic Tips is that they blow up under high velocity impact, which is certainly gonna be the case with a 50 yard range, so the heavier bullet makes better sense.

As far as the specs, that's something Win doesn't disclose, but I have just disassembled several of their rounds and interperlated. I have NOT taken a 150 Gr factory load apart. Two things come to mind though--first, are the bullets you have to load the CT coated bullets or the Plain NBT's. The reason I ask, is that with a 'friction proofed' bullet, you can( and may need to) load a higher charge to get equal speed/pressure, so be careful if you are disassembling factory rounds and trying to match up powder charges if the bullets differ. Second, pay close attention to the cartridge overall lengths and case fit in the WSM. It is easy to size sucyh that you do not have ENOUGH clearance between the shoulder and the chamber in the WSM's if you are trying to minimally resize--JME.

I feel pretty strongly that Win loads their factory 270 WSM rounds with Win 760 powder, and it is a shown powder in their reloading data for the 270 WSM. I would use that data and follow firm reloading protocol and work up to a load that shoots well in your rifle. If you have acess to a chronograph, you can tell a lot about your reloads compared to factory fodder as you develop your load.

R Flowers, one tip on trying the TSX's and E-tips, I have found both of these monometal bullets like a LOT more jump to the lands than the traditional bullets like your fav partitions. It is kind of a double negative in load developing though, in that the mono's are longer than lead core bullets, and they (the monos) need to be seated deeper into the case, often consuming powder space....I have been able to get enough of my preferred powder into my WSM cases and seat the bullets deep enough to get a jump that would produce good accuracy, but in several instances this resulted in a compressed load. I dont really detest compressed loads, if it's very light compression, I don't mind at all, but ALWAYS check for COAL growth if you load a compressed load. I have had several, especially stick powder loads, grow unacceptably after 3 days or so, so pay close attention if seating a bullet deeper and deeper to the compression.

Good luck all!

fish the close range blow up was what i was worried about wich is why i stuck with the 150's. while i do make longer shots i just so happend to shoot the first deer with this rifle right at 50yds. and hopefully i will get the same results with them at longer distances. to date the longest kill ive made on a deer has been right at 225yds with a 270 win shooting the 130 nbt's and had good results with that so hopefully i will see the same with the 150's in the wsm. for the life of me i can't seem to remember what powder i picked up for loading them i did get the powder recomendations off of winchesters website seems like it was rl19 but could have been 17 im away from home right now. also i ended up going with the regular winchester bt's because they were cheaper and from what i can see are identical other than the lubalox coating witch as far as i can tell should not affect the performance of the bullet. i geuss my hopes of duplicating the factory loads is out so i will be working up an audettes ladder and see what i come up with.

I vote for the 140 accubonds, love them! and try the magpro powder it works great in the 270 wsm!

Ditto on that !!! 140 Accubond at 3250 fps is heap powerful medicine. Also very accurate. I get .25 MOA 3 shot groups with my Savage @ 100 and .5 MOA @ 200 every time I take it to the range. I love Magpro and Accubonds.

Count another one for the 140 gr Nosler Accubonds. My favorite powder was Vihta Vuori N-165, but I can't bring myself to spend $40 for a pound of powder. I also get decent results with Accurate Data 86 (canister grade 3100). I have quite a bit of it since I got it for around $9 a pound a couple of years ago. (BBHO*)

The 110gr TTSX gets my vote. I have used them on quite a few deer and pigs from 25 to 390 yards and out to 325 it is hard to tell the diffrence in the wound channel. At 390 I did recover the bullet in the off side hide of a large Muley after about 30 inches of penetration. This is from a 270 bee with mv @ 3775. TSXs do like the Weatherby freebore, but I would guess they would still be quite accurate from the WSM.

I'm happy with my 130 gr ballistic tips for now, if I were to take a trip out west I think I'd probably be taking a serious look at the 110 gr tipped triple shock or perhaps the new Hornady GMX.

130gr Accubond at about 3200 has worked very well for me. The bonded bullet solves the potential problem of "blow up" at close range, and 130gr is plenty for deer.

Another vote for 140gr accubonds. I have had great results with RL-22 in my handloads.

Factory Winchester 130gr Ballistic Silvertip shot out of mdl 70 270 WSM at 3254fps. It is rated at 3275fps. Federal has some loads rated at 3300fps.
This is about as fast as a 140gr Rem 7mm Mag.
I loaded some 130gr Accubond with R22 and got 3050fps with close to min charge from Lyman data.
I can push a 130gr 270 Win to 3100fps with 58gr. But the WSM has more capacity to push with handloads into 270 Weatherby territory.
