Re: 308 To Ackley or Not
I don't know a lot about Howa's, but I do own one in 22-250. The reworked trigger is, to my mind, better than a Remington. The accuracy is only mediocre to average.
I would not punch a factory chamber to Ackley, waste of money, in my opinion. As mentioned, not much room for improvement in capacity on a 308. The gain is a small increase in velocity and longer case life. If you want higher velocity buy a 300 or a 30'06.
No, I don't see much point in altering the factory barrel. Fireforming is a chore and I don't see that it would be worth it.
Good hunting. LB
