shortest length for a 270

If I was to trim a 270 to add a can on it, what's the shortest length for reasonable accuracy out to 400m?
I don't handload so would be relying on quality factory ammo for performance.

accuracy doesn't need a long barrel, often guns get more accurate with shortened barrels. velocity does suffer if you plan to go to 400m I wouldn't go any shorter than 20 inches, thats without running the numbers thru a ballistic calculator. someone with one might do it for you tho.

what bullets do you use eg. federal 130 gr blue box?
how long is your barrel at the moment?

400m, shit, ditch the .270 and get a 16" 7mm08, an A-tec and some good handloads


(a change of calibre is not necessary but a 7mm08 would be more efficient and have much less blast from the shorter barrel)

I haven't bought a 270 as yet. Keen to put a can on one without making the OAL huge. My 243 is 20 inches and the Gunworks can makes the OAL 26inches. It can be a pain if bush bashing but not a prob on the tops. So a consideration is when I buy a 270, is do I cut it and thread for a can, or leave it as is.

Gimps advice is good. Why the hang up on 270s?
The 08 cases are more efficient and suffer less from chopping the barrel.

I didn't think there was much of a step up from a 243 to 7mm08. Same case, bullet change from 6mm to 7mm.
270 pretty much knocks everything down, so really heart set on 270win, but option to add suppressor or not.

Run the numbers. The energy difference between 243 and 708 is huge. Yes a 270will drop any thing but used properly so will a 243. Ive owned 2x270s and imo the boot and bang you get for performance you may aswell go to 7mm mag a small step up in recoil for massive ballistic gains. And off the top of my head i think the numbers on the 7mm08 arent to far off the 270 anyway. If your heart is set on one 24 inch is optimum and 20inches i would consider minimum.

if you havent baught a gun yet then as a chop and supp jobbie the 270 isnt the most Ideal candidate.

I would stick with 08 case. My 19" 7mm08 runs 140s at 2800 . Have had 4 kills at 400-450 with it without issue and handy in he bush
I have one of the older shorter greystone suppressors on it

That is some of the best advice I have seen on here in a long while tussock.my first rifle was in 270 in all fairness I only shot animals to 150 m buti bet if I was to shoot out past 300m these factors would have mybe seen some bad results that I wouldnt of been ableto explain so had I known this I would have made my first choice back then a 08mm

If your going to shoot a .270 past 400 you should consider something like the SST or Accubond with a high BC. Factory ammo using these bullets is expensive so you probably want to consider reloading too and using 22" barrel as a minimum.

What this means in terms of comparison between rounds if, while the .270 makes a huge fuss, that projectile has a parachute on the back of it. You wear all the impact and recoil, at 400m an animal is getting hit by a 130g projectile going quite slowly. Its an overbore round, so you need all that case to make use of all that powder. Also, as you are planning to use factory ammo and .270 is a very old load, the ammo has been loaded down a lot for the old guns. Its not as powerful as it once was.

An 08 case with a higher BC projectile, like .260 or 7-08 will have more down range killing power, for less recoil and less muzzle blast and it is not an overbore round, so it does not need all that barrel.

270 would always be a poor choice to shorten the barrel on, because its overbore already. It is already an inefficient round. Guys who don't own chronographs and ballistic calculators look at that great big 06 case and feel all that recoil and noise and think "wow, what a beast".

But because all those .270 pills were not made to fly, they slow down real quick. So what are you left with? Your left with the close range performance the other guns have, with mountains of recoil and muzzle blast, but you lose out on the down range performance that some of the much milder, more pleasant to shoot rounds like 6.5x55, 7-08 etc have.

Thats not counting wind either. Your average off the shelf .270 ammo with a normal 130g pill, will have the wind bucking ability of something akin to a .223Rem. If your Tahr hunting and its blowing its guts out, then it will suffer, where a decent hunting projectile in 6.5mm or 7mm will fly a lot straighter, and give you more chance of hitting your killing spot.

If you get a .270, chose one of the very few decent projectiles, and give it enough barrel to reach its potential, then its a beast.

But no one does that. All those people with .270 hunting rifles for "flat shooting" hard hitting guns are kidding themselves. Yeah, they do the job, but in reality not as well as a lot of other smaller, less dramatic rounds.

Go check your friendface messages and then tell me that I'm Real Dumb

Interesting.

The above statements ring very true with me. I re-started hunting with a 270 with a 20 inch barrel. Heaps of muzzle blast, ringing ears if no earmuffs used. Killed a few deer with it, probably scared most of them to death. I was very dissapointed when I printed some rounds at 300 yards. The short barrel and factory ammo gave something like 11 inches of drop at that distance. A 30-30 would do just as well! In short all bark, no bite. To unleashe the mighty 270 it beeds a bit of barrel. A 308 / 708 may be the best option if you are adding a can.

incorrrect, would not use the accubond, just because of its b.c doesnt mean its a good killer at lower speeds eg longer ranges

Sort of. There not bad with a stoutly loaded 140sst or 150 berger. 600 yards easy. Mid range. But yea for what they are a 7mm mag is leaps and bounds ahead in pill selection and performance for a small gain in recoil.

Or a 7mm08 for real similar recoil but waaaay better

I'll get a 7mm-08 when hell freezes over.

I love the fact gimp.is promoting a 7mm08. Not long and he will suggest one in tikka :omg:

I don't see why it's unusual? It's a sensible calibre and I've been pro-7mm08 since forever.

.270 is actually perfectly fine, you can push the 150 Berger pretty fast.

The 7mm08 will be slightly more efficient from a shorter barrel and there's more than 1-2 decent bullets to choose from, although .277" bullets are only going to get better from here

If you chose and efficient bullet, like a 150gr Berger, and got it leaving the tube between 2700-2850fps, it would be very capable as an LR rig. Problem is you will be using a good amount of pretty slow burning powder to fill up that big case, which rules out chopping the tube back. Your wallet will get raped if you buy factory ammo that has a half decent projectile loaded, and the cheaper (I use that term loosely) factory ammo just plain sucks balls if you do anything more than bush hunting. The 130gr Federal Power Shok load was my go to factory load for .270 when I thought it was the only round worth considering. It looks like it is loaded with a pistol bullet and probably has a similar BC to boot. It did anchor deer though, boiler room shots were catastrophic. See the light and get a milder round that shoots better bullets.

Hi guys, dont want to 'hijack' this thread, does the same apply to '25-06 cal'?

i.e. what would be the 'best' round for factory ammo for this cal, for both bush & LR hunting?

Same issue as .270 - Over bored, requires a big charge of slow burning powder to get good load density and speed, poor selection of bullets

I have 2 mates one has a 25-06 the other a .270 they both always say they are really flat shooting. Is this real or just they made that up based on they think its flat shooting because of the huge shell

Because it's a big arse round flicking a small light weight bullet out of the muzzle, so they think there will be "less drop". That might be true out to like 300 yards, which isn't long range shooting.

Flat shooting is really a myth. All modern calibers will be within a couple of inches of drop from each other at 300. Its after 4-500 that good bc comes into play thats were the 277 & 257 fall off. Bullet drop is a non event once you start dialing. There are super dooper over bores that make bullets hum like the weatherby 257 magnum ect and they will be ever so slightly flatter shooting but its really a moot point. The 25/06 and 270 are fine rounds that kill deer dead but they are being made redundant ballisticly by bullet makers not upping their games in said cals.

The best long range factory laod for the 25/06 is the hornady 117sst superformance. Or winchester 115 grain ballistic tips. I prefer the first

Flat shooting is not "A Real Thing" and it is silly old person talk from before anyone knew anything. Much like "an accurate calibre" and so forth.






yes disclaimer benchrest blah blah blah no-one cares

Big thanks guys............sorry to admit it, but 300 yards is 'long range' to me!!!!!!!!....would only try that prone or using a tree branch as a rest!!!!!!!

Dont think many would be trying it free hand haha

What's classed as flat? A 7mm that's 4.5mil to 1000m? With 100m zero. . .

Which is why us .277 shooters are eagerly awaiting the new fan dangled long range high BC projectiles from Nosler arriving in Nun Zud.

Like, it's going to be some intensely annoying to do wildcat thing with a short barrel life and the worst muzzleblast ever and I don't want to be in the same zipcode as it

they're not going to be that high unfortunately. those are going to be found to be exaggerated when someone does testing on them (not "in a paddock" drop testing because you can't get precise enough)

Mate i take a rest on any shot if theres one handy. Shooting past 200 a bipod or prone shot is a must for me.

I missed this but .25-06 is Real Bad.

Like don't get upset if you've already got one, but there's literally no reason to buy one at all.
