    Subsonic .308s

    Anyone tried using Sierra 165gn(2140) hollow points? These used to go well in my Tikka at supersonic speeds. About to set up for subsonic and thought these might be worth a crack?

    IMHO & from my experience the best way to hunt with a sub sonic 308 etc is to think where would I shoot this with a .22lr.

    The theory is big long pills so they tumble & cut, they won't expand.

    The bigger the calibre the bigger the mess.

    The tragectories generally make a rainbow look straight.

    Apparently there are special sub pills available that do expand, Spanners was going to be making them IIRC

    Just remember a subsonic 308 etc makes a 223 look like a big magnum in performance.

    FWIW my $0.02

    To make a 308 sup work a good expanding heavy bullet is in order and it sounds like spanner is the man to talk to
    1000yds is fun, 1500yds is getting interesting, 2000yds is exciting, 2500yds will blow your mind

    That pretty much sums it up but IIRC if you drill a already frangible bullet IE 30/30 pill it can be made to expand at sub velocitys

    [QUOTE=Spanners;7759]yip - I have a Corbin Hydro press[/QUO

    Some of the best subsonic projectiles I have used in 308 rifle cartridges are intended for pistols. Most have a very large hollow front.
    Stalking the edges of my uncles farms I cant remember ever having shot a deer past 100yrds with subs, most have been inside 60yrds.

    Years ago I made a die that held a 150g 30 cal corelokt, you could file the front off and drill the nose, I never shot a deer in the shoulder with that modified projectile, instead I chickened out and shot them in the side of the head. Always intended to test them on goats but never did.

    Large open hollow nose for good 1000fps expansion

    Then you will be onto a winner, They can do it with a pee rifle so it must be possible.

    Thats one aspect of reloading i would like to try some stage, ive merely opted for the "simple" cast loading and experimenting with variations of the Loverign design, ive one that i can HP but i think thats only just on 180 i think, could even be 160's. I need to do more work on it and the alloy mixes.

    If you dont mind me asking what did the set up cost and where is a good place to start?
    I appreciate & respect differing views, I greatly value the benefit of good conversation around differing opinions & respect points of view contrary to my own, however when you’re a belligerent self-opinionated obnoxious troll like individual, +1 to the ignore list

    I brought the press used (just) and with some dies.

    NEW price on press is over $8kUS and dies are over $1k a set - with a waiting period on dies of up to 2 years - I'm 1 year into it and still not got my punches I need
