Howa Mini 223 and 556

[AlaskaRed]

Has anyone shot 556 out of their 223 Remington chambered howa mini? I know usually it is ill advised but a lot of this has to do with chamber and throat dimensions that do vary from factory chamberings. Wondering if the howa mini 223 chamber gives enough room to accommodate plus being a bolt action can handle any potential pressure spikes.

I wouldn’t think twice about it in a bolt action in good condition.

I shoot 5.56 out of my 223 Tikka all the time. No problem.

Yeah not generally an issue in a bolt action, but the Howa Mini is a good strong action.
Never had an issue with mine firing 556

Yeah, got about 100 rounds through mine between yesterday and today. How has accuracy been for you in your rifle? What ammo has been shoot g best for you?

Mines an aftermarket barrel now which has really improved accuracy with all ammo.

With the original barrel I used PMC Xtac it was 2-3" groups, fine for cheap plinking

I’ve got between 1800 and 1900 rounds through my howa mini 223 since September. All the factory rounds have been 5.56 and all my reloads are 5.56 pressures. No issues for me!
