Hi all I'm after some help on what weight projectile to try in my 223 the barrel it is 1in12 twist 25 inch long trying to get out to 600y with it. Don't no if 69g will work in this set up.

You may be pushing to use the 69's in a 1:12
Last time I had a 1:12t 223, I used 53 smk's with ADI
Benchmark 1. Worked ok, only shot it out to 300m

You should be able to get out to 600yds with one of the 60gr varmint bullets. Nosler Vbt,
Sierra HP or Hornady vmax. Enough ar2208 to get you up around 2900 fps would be worth a try.1 in 12 twist is not ideal but you can only use what you have so have fun with it.

Thanks I was tying to find a projectile around the 60g I try and find some and see how they go is there any way to work out how fast they be going at 600y

If you dont have a chrony your reloading manual should give you a rough idea

At 600 you will be down around 1300fps

What speed do they fall under the sound barrier 1200fps ?

Yeah a bit less.700 would be a worry.

Hi jmc,

It is worth noting that if you wish to compete in F standard you will need to shoot one of the following approved projectiles.

National Rifle Association of Australia Limited
Standard Shooting Rules Page 109-110 of 127 February 2013 Issue - Version 2a.
223 Calibre
Sierra - MatchKing:- .224 69 grain.
Sierra - MatchKing:- .224 80 grain.
Hornady – Amax:- .224 80 grain.
Nosler – HPBT:- .224 80 grain.
JLK VLD:- .224 80 grain.
Berger Match VLD Target:- .224 80 grain.
Berger Match Fullbore Target:- .224 80.5 grain.

So really you should try the 69 gr matchking (but only buy one box as it probably won't work as you suggest). And if this doesn't work you will have to shoot in F open. This is not a major issue though and you should be able to enjoy yourself anyway.

I've tried 69gr SMKs in a 1:12. They did hit the target point first but grouped like a shotgun!
