Wich bullet weight is best for 1:10 twist?

[Guest]

Hi, great forum :grin:

I was wondering if someone could tell me wich bullet weight is best for 1:10 twist in 270wsm. 130gr, 140gr, or 150gr ? The answer I keep hearing is " All bullets for .277 should shoot fine in 1:10." But, one weight has to be optimum, they cant all be equal. Thanks guys.

What type of game are you hunting? That has more to do with which bullet you use. I have a 270WSM and have developed loads for the 130ET, 140AB, 150PTG, and the 160PT. They all shot great groups once I found the right combination.

IMO, if you are going after deer, elk, or moose, the 140AB up to the 160PT are my choice. I personnally use the 140AB for everything, but since I live in a "lead free" CA zone, I use the 130ET there. I would use the 130ET, 130AB, or the 140AB for pronghorn and smaller animals. Again, just my opinion.

I hunt whitetail. But I also do some shootin at the range and want the best groups possible. Using factory ammo by the way. I guess this didn't belong in the reloading forum, but it didn't seem to fit in "Hunting" or "Rifle" either. Besides, you reloaders know your stuff.

Equal or not, I have been able to get a large range of bullets to shoot well in my 270WSM. My rifle is a Winchester Model 70 and I believe it has a 1 in 10 inch twist. I have shot very good groups with it with everything from 90 grain Sierra's to 140 grain Noslers.

Sure, some have been picky, but most all have shot well. The 90 grain Sierra HP has shot VERY well in three Winchester 270 WSM's that my buddies and I have. (Groups of a half inch were commonplace.)

I used to shoot 140 grain Parititions in mine for game and it shot them very well at 3200 fps. When the lead ban in this part of California came about I had to do some load development with copper bullets.

The 130 grain Barnes TSX and Nosler E-Tips both just shot ok, nothing to brag about. Groups in the 1.0 to 1.5 inch range. (Keep in mind the 140 grain partitions averaged about 0.6 inches.)

Then I tried the 110 grain Tipped TSX Barnes bullets. I shot some groups down around 0.3 inches! They shoot great and I get right at 3600 fps!

I have a friend who has shot several deer and hogs here in CA with that bullet and it has performed quite well.

Are you going to be reloading or using factory ammo?

+1 on Win Model 70 and use of the 90gn Sierra HPs. As for the 130ET, I was able to achieve sub-MOA with the following recipe:
Win Brass trimmed to 2.09
Primer: GM215M
Powder: 60.5gns of IMR4350
COL: 2.88"

My Winchester model 70, with a 1/10 twist in .270 Win shoot submoa with everything from 90gr sierra's to 150gr solid base, and it really like the 140 BT. To say it shoot great with all of these weights is very accurate.

Since your using factory ammo, find which shoots the best. Any of the weights you asked about are fine for whitetail. The "optimal" bullet for YOUR 270WSM, is the most accurate round YOUR gun will shoot.

 

[Antelope_Sniper]

Most factory guns are rifled to stabalize the heaviest bullets commonly avaliable. So, "in theory" a 1 in 10 twist for the .277 is about "optomized" for a 150gr lead bullet.
If you are interested in accuracy, maybe it's time to start handloading?

Welcome to the forum.

Yes 1:10 will do about everything ion this case.

Thanks for all the help. I will just pick a few good factory loads and see wich groups the best, regardless of bullet weight. So far I have only shot Federal 140gr Accubonds and they seem to be pretty descent. I'm also going to try Winchester 140gr Accubonds and see how they compare. I'm not a big fan of the all copper bullets just yet. Maybe it will have to grow on me. I was thinking about trying the Winchester XP3 until I read alot of bad reviews about it. Seems most folks have trouble getting good accuracy with them. Anyways thanks again for all the quick replies.

HEHEHE, bear in mind that a bag of 50 140 grn AccuBond 2nds is only 15.70 at the www.shootersproshop.com, you'll use about $10-12($20/lb) worth of powder and about $1.80 worth of primers to produce 50 rounds with your fired brass.

Most likely, this handloaded stuff is going to outshoot factory ammo once you get the hang of it. That's 2.5 boxes of premuim ammo tailor made for your rifle for under thirty dollars production cost. And if you can hanld using lee equipment and RCBS dies I think you'd be equiped and up and running for about 150 bucks.

And it isn't that hard if you have this whole panel to dip into for knowledge.

DId I convince ya???? :grin: :grin: :grin:

I have actully been giving it some serious thought. May give it a shot in the near future.

An RCBS press would look really nice under the Christman Tree :grin:

270wsm,

Welcome to the forum, glad to see you here.

Richracer 1 is spot on. Every rifle is an individule so you will have to determine exactly what your rifle likes.
I hope to take a serious look at considering reloading. You will indeed produce accurate loads at a much lower cost than buying factory ammo.
And all your friends here at Nosler are here to assist you. :grin:

If I try several factory loads and found that my gun shoots 140gr Accubonds the best, then I start reloading, will I have to try all the other bullets again or stick with the Accubonds?

To a small extent yes, but you will have to figure out via load development which powder, primer, bullet seating depth works for your rifle. Reloads most of the time achieve better accuracy that the factory stuff, but the powders the ammo makers use is sometimes not available to the public, so may not see the velocity of the factory stuff.

This thread alone will give you several powders to consider. Also keep in mind that large rifle primers (mag or std) are kind of scarce.

Any questions, just ask.

I have been looking at RCBS website at all the reloading equipment available. It looks very complicated. It seems there is alot to choose from. I wouldn't even know where to begin. FL dies or Neck dies? Single stage or turret press? Digital scales or Triple beam? There is alot I would need to know before even purchasing the equipment. I am a little obsessive compulsive, so I would want to purchase high quality equipment. How much would it cost me to get started?

 

[bullet]

1-10 twist will do for all the weights you mentioned. Reloading is best to keep simple. Press (single) die set (full size), scale, case trimmer, primer pocket tool, primer seating tool, case de-burring tool, calipers, powder, bullets and just take your time having a ball. Do what the reloading manuals say is safe and don't get technical, don't rush, just keep it simple.

Something like this wouldn't be a bad place to start:
