They are a Japanese made rifle that borrows a lot from the Remington 700. In fact scope mounts for a Remington will fit Howa MOST of the time. The only exception is if you're using a one piece base on short action rifles Remington and Howa are different. Long actions are completely interchangeable and if you're using 2 piece bases on short action any Remington mount will fit. Many consider them a better rifle than the 700. They do have a better extractor and trigger.
Over the years they have been sold under several names including Weatherby Vanguard and Mossberg 1500. Overall I like them, but all of them are overweight. They make some "lightweight" versions but since the actions are so heavy the only place to lose weight is in the barrel. I'd rather keep some weight in the barrel and lose it in the action. I've had 2-3 different versions over the years. None were inaccurate, but they are simply heavier than I want in a hunting rifle.
In a top tier rifle I'll take a Winchester 70. If looking at less expensive hunting rifles the Tikka's have been the most accurate for me, but for about 1/2 the cost the Ruger American Predators are a very close 2nd.
The Ruger 77 series is a completely different rifle closer to a Winchester 70 in function. If I needed a rifle to be 100% reliable, no excuses for weather, or abuse the 77 would be my pick. But not my pick if accuracy were important.
