Howa Mini .223 max COAL experience

[KyleR1985]

Just picked up a mini for the wife in the classifieds.

It’s got the oregunsmith bottom metal.


Anyone running longer than standard mag length COAL hand loads in their .223 mini? Trying to get a sense of what limits are there. Also interested in whether the mag or the chamber will be the limiter. Haven’t seen much written on chamber max coal.

Thanks!
