The Howa's are a very good action with a pretty good trigger that is easily adjusted as long as you don't like 1 1/2 lb triggers.
They have several features that I really like. The extractor is one of the very best of factory rifles on the market and there are also holes in the bolt to vent gas in the event of a blown primer to keep gases away from the shooter's eye.
The Howa's that I had were a 223 sporter and a 22/250 Varmint, both of which presented examples of good craftsmanship, good design, and 3/4" accuracy, perhaps a little long throated for my likes.
I shot them for a while, got bored and sold them. One of my best friends bought the 223 and turned it into a 17 Mach 4 using a Pac Nor barrel and that little bugger would shoot with the 25g Berger bullets touching at 100 yards with loads that varied from 15.5g of H335 at 3550 fps to 18.5g of H335 at 3850. We shot a mountain of crows, ground squirrels, and jack rabbits with that rifle up in N. Nevada.
Another nice thing about the Howa was that it would hold 7 rounds of 17 Mach 4.
