I need help! 270 barrel chop, cant make a decision

interesting about the magnum can..myunderstanding of it..and it says so in literature on cans...below 30/06 level std can...above 30/06 level magnum can..the case capacity is the same as .270 mine has std gunworks spartan..has had std DPT both worked fine...I PREFER the longer skinnier spartan because it comes back further towards stock..there is NOTHING in it weight wise,noise wise,price wise or sticking out the end wise.... tell you something for nothing,chuck the SS blast baffle into DPT on mates 25/06 seems to have made it a hell of a lot quieter..definately worth trying one.

If you are thinking seriously about chopping it ….then you really do need “help”. Restore it by all means, just don’t bastardise it. It’s an heirloom

Greetings,
You speak of your Grandad in the present tense which leads me to believe that you are in the younger ages group. I suggest that you make minimal changes to the rifle other than what you have already done. Suppress it if you like but leave the barrel as it is. If you chop it I can just about guarantee that one day you will think "Why the hell did I do that"? and it will bug you for the rest of your life. Please believe me on this from someone in your granddads cohort. I would dearly like to have a rifle either of my granddads had owned but the only one either of them had was a Lee Enfield in 1916 and 17 and the army took it back.
Regards Grandpamac.

I’ve got mine (tikka) cut to 18 inches and it’s awesome. Hand load 145gr eldx with superformance to 2925fps, about 75fps quicker than the factory eldx loads went when the barrel was 4 inches longer.
If going with a dpt suppressor you’ll probably want one of those stainless baffles if you cut below 20inches. I know Hardy won’t stand by their warranty on any of their suppressors in a 270 shorter than 20.
Just to side track a little.. when I chopped the end off mine I got a spare T2 brake I had indexed for it at the same time.. makes for a light wee rifle but none of your mates will go hunting with you if you do that!

Cheers

Missalot......you put a loudener on it!!!!!!! yeah nah stuff that for a game of soldiers

I chopped mine to something like 19". I can't actually remember and I'm to hungover to go and measure it for you. I run a DPT on it as well. Its usable but I'd love something shorter, a proper bushpig would be nice for the kaimais.

yeah I will put in two cents worth- the rifle is now yours ? you can do with it as you choose - I would go 20 in and a can - it is not a Holland and Holland

Yep… a lot more muzzle blast than having the loudener on a 24 inch barrel… I got sick of hunting by myself so put the suppressor back on 😂

Missalot...years back a mate had an early browning 25/06 with the boss system on end of barrel....a weight that moved on thread to change harmonics and it was ported...wallaby went hopping off down hill,mate opened up..the rest of us ran backwards blocking ears,the dogs down the hill looked funny trying to run after wallaby with front paws stuffed in ears...HOLY SMOKE that thing was obnoxious.

I went from a suppressed 22in tikka 308,down to 20in,down to 16in up to 18in ,up to 22in tikka.Tikka 22"pretty quiet with a gunworks suppresser on it.Shoot one deer,other deer just stand there looking at their dead mate.If you walking in the bush,just take suppresser off if it bothers you.Or dont cut shorter than 20"s as other have advised

I have just had my Howa 1500 270win cut down to 20” and suppressed by DPT. Too soon to tell how the balance etc is, but they did a stand up job!

If you want to make the rifle more useful without altering the originalness then perhaps consider putting a new (or secondhand) barrel on and cut it as short as you want. Keep the original barrel in the safe then when/if you want to restore the rifle too it's former glory you can refit the original barrel and put a period correct scope on it.

I have just been in the same situation. I inherited a model 70 22.250 carbine. I had plans to tidy it up and leave it original, thinking it would be a great gun for the kids to use .but after putting a few rounds through it made the call to suppress it. Left it at factory length (20 inch). Has made it way more user friendly, especially around young ears. As already mentioned, put a thread cap on it and good as new.
I think it all depends if you want to actually use the rifle or just sit around admiring it and fire the occasional shot?.

My vote is 22" minimum for an -06 based cartridge. If you notice the difference between a 20 and a 22" barrel in the carry, you're either a bit like the princess in the "princess and the pea" nursery rhyme or you have ducks disease and your arse is a bit close to terra-firma.

Remember with a xx" barrel you are measuring the chamber which only houses the case, your effective barrel length on a 20" barrel is 17.5" thereabout for the powder to do it's work. You need around 20" in an -06 length case to consume all of the powder in the barrel otherwise you tend to get horrendous muzzle flash and the powder granules getting ejected are pretty nasty on suppressors both in general wear and tear and in the amount of crap that gets caught up in them which can cause corrosion if left on the gun. Similarly I wouldn't drop back any less than 20" on an -08 length case, yes they are 'handier' but you aren't getting any advantage over a 7.62x39 real world and the x39 is nicer to shoot with a shorter barrel and cheaper.

Not really. Without looking on the computer I'm picking there will be some powders that burn as much if not more in an 18" or 19" barrel than other powders in a longer barrel. So with that in mind how far do you need to shoot. An 18" or 19" with a higher bc projectile going 2900 plus will kill fine with more than enough energy over 750 yards. I have had several .270s and still own one and I couldn't tell the difference in recoil and muzzle blast between the 19" tikka and 22" tikka. There is a reason the .270 was the leading contender out of the "bush pigs" NZ Hunter done.

As for a short 08 case being similar to a 7.62x39. Not even remotely close.
2200 max with 150gr out of a full length barrel will be going pretty slow out of a 16" barrel and be severely lacking on the expansion and energy front. My 16" .308 with 168gr amax going 2520 fps expands reliably out to over 600 yards and kills well out to that range too. I used a 7.62x39 for a bit and it was a very poor killer especially with the cheap ammo. And god forbid you see a deer at 250 yards. So as far as having "no real world advantage over a x39" is a fair bit of a yarn. A 12" .308 is still better than a 24" 7.62x39.
