Thread: 300blk on a howa mini and mag v std supp

Hey lads, looking at building a 300blk on a howa 223 mini action (10inch barrel 1:8 dedicated subs) and have a few questions.
Will the mini action mag fit and feed all factory ammo (looking at hornady 190subx) and will a 240smks loaded to sub speeds (powder capacity) fit in the mag.

Also ill run a dpt and wonder if the magnum version will decrease noise levels at all ??
@DPT maybe


Thanks team.

Why not use the 7.62x39?

Personal preference and factory ammo.

Why a 10 inch barrel? What happens when the cops unscrew the suppressor, making it less than 762mm overall, and then charging you with possession of a pistol?

Just like they did to that guy in Whakatane recently after they took the suppressor off a 10/22 leaving it 14mm under length. He got found guilty in Court.

Yes the magnum will be a little quieter.

Hey mate thanks for the constructive comment.
10inch as only need to acheive subsonic speeds and want it as handy as possible.
Only read so far but the mini action rifles oal is 40inch with 20inch barrel. So with a 10inch should be just over legal length.

Sounds like the police tampered with evidence before rifle was measured.

any link to the ruling? I cant seem to find one, or was this the case that the Police suddenly threw out?

Yes it's hard to get factory 7.62 subs (only seen them once) and most 7.62 barrels seem to be about 1:10 which doesn't like the heavy subs.

Well, whatever happened, they measured it with the suppressor off and it was 14mm under legal length and the judge agreed and he got found guilty.

There was something about him getting in a fight, him calling the cops saying had had a gun to protect himself if he needed to and the the cops turning up and taking his guns.
