Getting a barrel from Hart, any reason you can think of not to get 1/10? and 24" length?

This rifle will shoot 130, 140 90% of the time and may get a few 150gr's now and then.

1/10 and 24" just seen to be ideal for this caliber. But that's my mind, so what say you?

I agree.

I have two 270s right now, one with a 24" barrel and the other with a 22". For what it's worth, the 22" is consistently faster than the 24" with the same loads. I suspect that velocity (like accuracy) variations are as much a function of each individual barrel as of barrel length. That said, I like the 22" barrel for weight saving as I prefer a lighter weight rifle in a 270. Go with what feels and looks best to you.

I'd go with a 23" barrel, nice compromise between a 22" and 24". And since it's a custom barrel it's a little different than what most factories offer.

My first custom 270 used a Hart SS 1/10 twist at 24" long next one I used a Lilja SS 1/10 @ 24.6" long. Kind of funny but I shot the same load in each rifle 54gr/H-4350 140gr TSX the Hart barrel was 3172fps and the Lilja was 3191fps and that was a max load from Barnes manual. I did drop the load back 1.5 gr and that got me more in line with Barnes velocity with both rifle mid 3000fps.

I shot afew PD with both rifles never hunted with either rifle use the Lilja 270 as a back up on an antelope hunt. Finally gave my nephew the Hart barrel 270.

Well good luck

I'd go with a 1 in 10" twist and 24" barrel. I've been getting 3000 fps out of my 22" barrel with 150g Nosler Partitions and H4831. It's a great elk / bear load and does just fine on deer too!

I like the 1-in-10" twist for the .270 chambering. In my 22" barreled M70FW I use 130 grain Hornadys and a Winchester case chuck full of compressed H-4831 at 3,180+ fps and 150 gr. NPs over a not quite full case of IMR 4350 at 2,900+ (both velocities chrno'd over an Oehler).

Very true!

Personally, I would go with a 26 inch barrel.

A few years ago, 5 brand new rifles were brought in here.
All were identical, Mannlicher Luxus models. All were in 270 Winchester.

We shot them with Norma 159 grain SP ammo.

The amazthings was that the fastest barrel was over 150 fps faster than the slowest one!!?

For what its worth you will be 2" closer to your game with the 24" than the 22" and thats about it.

I agree 100% w/Saeed.

We're just putting the finishing touches on a custom 26" '98 Mauser .270 Winchester w/a #2 contour.

The cartridge really comes into it's own when used at longer(ish) ranges, barrel length usually isn't an issue (when is it really?) for the types of hunting pursued and 130 grain bullets are ideal for this application eaking the best velocities outa the cartridge with the "standard" loadings of H-4831sc and our 130 gr. Swift Scirocco II's.

We can always cut the barrel back a notch or two if we end up with a sluggish barrel although we probably won't.

Good Luck with your decision & new barrel.

This is very much a personal preference thing......and it's why we make customs!

I'm a fan of 22" .270 Winchesters....they just work fine and don't bang the tree limbs as much!

1 in 9 twist.
Yes the 1 in 10 works fine for 130 and 140 and you probably won't notice the difference with a lighter weight barrel. However; if you go with a 26+ and say a 4 or more countour barrel from Lilja and then want to streach the range a bit you will want 150's and in my experience the faster twist does work a bit better with longer bullets, esp. Burgers.

I have a 270 with a 1 in 10 27" Lilja that weighs in at 11 pounds and is wounderful for PD's at 500 plus as well as grain field whitetails. Honest 1/2 MOA or 1/4 MOA depending on me with 130's. With 150's its a 1 MOA rifle.

OK, WTF, that's still sub 6 inches at 500 yds. But you asked if it would make a difference and it does. The question is, do you actually care?

IMO, the barrel lenght would depend on your plans for the rifle. If it's to be an all-around hunting rifle, for example, for climbing mountains and still hunting the brush, then the 22" would be preferable. If it's to be a "beanfield" or "sendro" rifle, I'd go with the 24".

It's true that individual barrels can be fast or slow, but on average, the 24" bbl will be faster than the average 22" bbl.

I put a 26-inch barrel on a 1909 Argintine Mauser in 7X57, not because of the velocity increase but because it makes the rifle hold steadier. A longer barrel cuts down muzzle blast and does give more velocity everything else being equal. However, other factors are not always equal. For example, a 22-inch barrel with a tight chamber may give higher velocities than a 24-inch barrel with a sloppy chamber.

I'd go with a 26" barrel.
.270 responds well to the longer barrels.

Vapo-Doggie,

Agree wholeheartedly; but Hell, when I hunted Arizona (been a few years) a "tree" was about head high and they were well spaced out among themselves, too.

Gotta admit this is the only "out West" hunting I've ever done, So it sorta left a lasting impression.

Like Antelope Sniper; my hunting squeeze "The Winkelmeister" who is having the .270 built is from Denver, Colorado - he likes long-g-g Boomers.

Unless you're on a Power Company Right-of-Way here in The Fatherland a long shot is 60 meters and that snaking one through the trees. 20" is about right for not bumping the Roof, Walls & Window Jams of a High Seat, too.

I'm with everyone else. Stick with a 1:10 twist and a 22" barrel.Velocity gain/loss woud be due to barrel factors than length. I get 2930 fps in my Pre-64 with an original barrel and 150 gr. bullets. Plenty good enough.
Bear in Fairbanks

24"/130 Grain Ballistic tip/56 grains IMR4350/3120fps, out of my model 70. My 26" Model 700 shoots 130's near 3300fps. I like the longer barrel in the 270, and after shooting one since 1969, my 1st was a 22" Model 700, I have prefered the longer barrel. There is always an exception to the rule, but if you want to wring out the most performance velocity wise, a longer tube is required.

Ordered from Hart yesterday. 1/10 twist was a no brainer. Have some time to determin barrel length.

The 22" is as good as any. It's all what you get good at using. roger

1:9 or 1:10, either is fine but I will be toatlly different and suggest a 21 inch barrel. It is a little handier and doesn't give up enough velocity to matter in the grand scheme of things. I think individual barrels are going to vary more in velocity than a 20 inch to 24 inch barrel does overall.

Ah. Yes. But!

You will also be 2" further away from your muzzle blast and for me that, in a rifle that won't be fitted with a moderator, is worth the extra weight and carry hassle alone.

The first 270 I shot was a 22" barrel Churchill using Winchester Super-X 130 grain loads. It put me off the 270 Winchester for twenty years!

It was only when I tried one using a 24" barrel 270 Winchester that I began to like the round again.

I have an FN commercial Mauser with the thinnest 24" barrel I've ever seen on a factory made sporter. The stock is so ugly that it would abort a lady crocodile, to use one of he late Jack O'Connor's comments in an article he did on stocks. If I was smart, I'd restock thet rifle but for two reasons, I don't. One is it's damnably accurate and the barrel is "fast". It gives higher velocity than the other three rifles I have in .270. The other reason is it is a very light weight rifle. With scope, sling and a full magazine it sits right at 7 pounds even. The other two rifles with 24" barrels are noticably heavier as is the Ruger #1A in .270.
Years ago I settled on two loads. The 150 gr. Sierra Game King or the 150 gr. Nosler patition depending on what I'm hunting. I found that I get better accuracy from 150 gr. bullets than the somewhat more popular (?) 130 gr. bullets. Another benefit of the 150 gr. bullets is they don't tear up as much good eating meat compared to the 130 gr, bullets.

I use 24" in my 270 Win. Works great for me.

I have just 23 " and it performs very well...

Its a magnum in all but name and if you want to make the most of the 150s you'll do best with a 26" tube.
