    Recommendations for subsonic .270 ammo?

    Does anyone have advice on using subsonic .270 ammo, (short range bush hunting deer) and where to buy in NZ?

    The 270 case and bore is not suitable for subs mate.
    The case volume is too large for such a small quantity of powder and you could risk miss fires. I wouldn't imagine there would be too many 270 pills that would be a good subs either. You really need a heavy 200 grain plus lead pill with no jacket.
    You never know someone say I am wrong on this

    Anything is possible, but as said it's going to be a bit of a pain in the bum to get it to work right and reliably in such a case (it's a fairly hot performer and you're on the high side of case capacity for the bore size).

    Seems correct in all, except even a few grains of Trail Boss in a far corner of that case will still ignite consistently. You'd get a nice quiet .270 you could ethically/confidently only do head shots with.

    That said, point any firearm in a safe direction, it's relative, some people even consider .32ACP a mouse calibre, but its use in humane killer devices show you can put down big bulls with it... head shots again of course.

    as said above...the mighty poohseventy is a great round.....by doing what you are trying,you are hamstringing it back to really hohum....IF you intend to persist MAYBE 150grn speerspbt MIGHT expand a LITTLE bit...but it will only be a little....trailboss will do it,but you arent going to be impressed with terminal preformance...
    I played around with subs they are great for plinking,finishing shots and small game....thats the positive
    negatives....ricochette like hell if hit something hard...scary as faaaark......miss central nerve stem/brain by any amount and animal will walk away pissed off and wounded...and I mean ANY amount....

    you could download with trail boss..eg same volume of powder as normal stuff....it will probably give you 1500-2000fps and be quiet as heck...you will still have a LITTLE shock and some expansion WITHOUT the big boom or recoil....but you have in effect turned it into a 7.62x39mm....

    Get some fast bulky powder and develop a load.

    Regarding terminal ballistics, as above cast lead is ideal.
    But any projectile can be tastefully modified to improve performance. Swipe with a file across the meplat and few nicks with a knife up the jacket on the ogive turns FMJ into SP.

    Just make sure the first projectile has left the barrel before feeding it another.

    Thanks Cordite, I had heard of Trail Boss as a safe powder option, didn't know if it would be any good with the case combination, the .270 case being relatively large capacity. I'm probably not skilled enough to do head shots only

    Thanks Muzza, yes I have a nice gunworks over barrel suppressor but she's very loud even with that on (standard ammo). I saw a video recently where a guy took 3 deer out a few minutes apart each one with subsonic- was impressive that the others weren't spooked. I didn't know what cal he was using so thought I'd ask about .270 subsonic options. Thanks for the help!

    Thanks GKP, I'd heard of Trail Boss which is much bulkier than standard powder, but it sounds from what you say like the .270 isn't the ideal calibre to use in subsonic anyway. Cheers!

    Thanks Micky Duck, at least it would be a quiet 7.62x39
