Hi all So how short can I go with out starting forest fires?
What have you done how does it go?
what ammo would be best in a little gun like this (I have no experience with these little calibers)
I feel maybe the 130gr factory ammo move fast burn fast don't waste so much powder??
What say you learned people?
Performance would have to be pretty close to a short 284 one would think.
Be fairly hard on the suppresssor if really short.
Yea am thinking that will try get suppressor with a steel baffle or muzzle break Haha.Quote:

Maybe like 18" barrel
Don't the Duley's use a 270 as their bush gun? I'm sure I read Greg saying that when they weighed up all the calibres that the 270 was the best option. Probably counterintuitive to what we think as a bush cartridge; but he'd done the maths
284......he calls it fhe 284superpig.Quote:

Pretty sure it’s a .270 they’ve had on their latest episodesQuote:

@veitnamcam I'm sure I've heard him talk about and use a .270 cut down; usually for sika. I remember I was really surprised. But hey; I could be wrong! I often am haha
He could have changed his mind and needed a new cal to market as the ultimate bush pig.Quote:

Being .270 owner I just happen to have the Intel on hand.:thumbsup:
18 inch barrel. Dpt magnum suppressor.
Factory 130 fusions at 2800 fps
145. Eldx* 2965fps. ( hand loads )
Built a 16" 270 couple years back. Id still have it if I'd built it on a decent action, but I built it from a sauer 100 and it was the biggest pile of shit I've ever had the misfortune to come across. It performed pretty good though, 110gr prohunters @3100fps and 130gr bullets at 2700-2750 all using reloder 17
Greg has been using a bushpigged 270 for a couple of years. Last time I saw him he spoke to me about it. In a short barrel for the ranges they were using it for, with factory ammo, it outperformed both the 708 and 308. Almost went that route but stuck with the 308 as I wasn't brave enough hahaQuote:

Look at this. With its 18" (or 20") barrel if that's not a gun for all seasons, what the heck is?Quote:

Did they write a piece on bushpiging the 270 ? . Yes Tarh you might just be right that is very good performance. Any have any idea on the max range of the 145 edlx in this sort of configuration.?
jeeez Phil...I dont need a flashasmichaeljackson gonkulater to tell me that.... 3" high at hundy,near enough to dead on at 270 yards,backbone hold at 350 ...and that right there is all I NEED to know as dont use rangefinder...350ish yards is a long way with fixed 4x scope and with naked eye can pretty much guarantee Im INSIDE that range...
I'm in the process of cutting down an old XS7 .270 once I sort anew suppressor. The older HRE Gen1 will only allow me to cut it to 20' odd. Will sell that a buy a shorter can.
I'm getting 2940fps with my rifle out of a 22inch barrel, 40 Sika last year didn't argue with that load out to 475yds.Quote:

Duley et al used Federal 135 grn in the .270 that Derek shot the deer with.
A bit behind i would guess in the fact that the 284 has more effective barrel due to the shorter case, shorter fatter columns being more efficient, and off course the pitiful BCs of 270 projectiles. Still not a terrible option if your willing to accept you are probably severely limiting resale value of your 270 whereas doing the same to a 308 wouldnt likely do the same.Quote:

It wasnt the most efficient it just had the best performance and they determined it to suit them best a the others didn't have the power they wanted with factory rounds. Its like a 16 inch 7mm-08 and 284. The 7mm08 is more efficient based on powder burnt but the 284 still makes more velocity even if its one of those extra 50% to gain 10% type deals. They had a minimum threshold and to get it they had to go to a cartridge's with a larger case capacity or reload which went against the point of the rifle.
Any rifle can go as short as you like if you wanted a 16 inch 300 Win Mag theres no reason why you cant (especially if you reload).
The things that remain the same (or pretty much the same) regardless of barrel length is
- Powder Burnt
- Recoil Energy
The things that decrease with barrel length
-Velocity
-Powder Efficiency
-Suppressor Life
The things that increase with a shorter barrel
-Maneuverability (decreased overall length)
-Shot volume
All of these things are slight initially and the more extreme the chop the more extreme effects.
One thing to consider is usually the short and fatter the case the shorter the barrel can go before velocity starts to drop too severely,
the less powder capacity also has the same effect with lower powder cases not being affected by barrel length as much.
Typically heavier projectiles increase the time in the barrel and improve short barrel efficiency as well as tending to have better BCs meaning they keep it down range.
Reloading can claw back some of the loses of a short barrel but not all and if reloading in a longer barrel the gap reappears.
A 16 inch barrel and arguably an 18inch barrel of most hunting cartridge's needs a suppressor as they are bloody loud and will mess you up. They also have the same overall length as a non suppressed 20-24inch barrel that will damage hearing but not to the same level as an unsuppressed short barrel.
Cartridge's outside 308 and small calibres typically are hard to sell if they have barrels under 18inchs on the aftermarket. Shit even a 20 inch 7mm Rem Mag can be a difficult sell.
My opinion is that short bush pigs are cheap second hand so by a 2nd hand one rather than building one. The prices for a standard t3 vs one thats cut to 16 and suppressed are usually damn near the same.
Fiona's rifle is a 284. The men use the 270Quote:

Except that even a pedestrian 308 would be closer to 3k with 145gr and 22"Quote:

The thing I rate about my .270 is that it shoots most factory ammo under an inch consistently. I dont bother reloading with it as it's a sub 350 yard gun for Dad.
However 22" barrel and a suppressor ain't too practical (bought it like that), so I'll be cutting it to 18" and running a DPT with a SS baffle.
I was meaning the factory Hornady 145 ELDX are quite slow, however very accurate in Tikkas. I'm sure the federal factory still kills very satisfactory for them in shorter barrels and can pump their sponsor.Quote:

Found rather destructive on the fallow and went back to 22.250 on them, less messy processing.
That stuff they used was factory rated as 3,000 fps so I guess at 18" it would be something like 2875 at best, but as you say a good bc to carry it along.Quote:

Didn't group well
145 ELD-X Precision Hunter

Very accurate, ragged hole
145 ELD-X Handload Super-Performance, accurate final load (details on thread on forum)
Ave Velocity 3045 fps
Very accurate, ragged hole again. Must have got into next node up from factory loads.
Emphatic killer on animals.
Already have the 270 No one keen to swap it so will have to make do. @NZPureLamb
Wow Busy weekend and boom so much awesome information when I get back on line, thanks for the info guys.
Looks like I will be measuring up and seeing where I go between 16/18" I don't mind chopping the stock so will see what I can track down for the moderator with steel blast parts to take the Hell fire produced Haha.
should be a fun gun hopefully it likes the cheapest ammo I can find.
Ill be happy with Minute of Rabbit accuracy and that should make it fun and suitable for deer to 300m plenty far enough for a bush gun.
Worth a try of the Remington Corelock .270 if you are after cheap(well it used to be), it shot extremely well in my mates Marlin and didn't like the other brands when he decided to treat it to some more $$ offerings.Quote:

Good information there Darren, that could potentially end up untidy.Quote:
