The vertical grip helps if you're laying there sniping. Some people's hands do legitimately hurt in that position on a traditional stock, and it does help some people at really long ranges, especially if you're going with the style of being straight in line with the gun. I shoot prone laying at an angle to the shot holding the scope or the forend so I don't notice anything. You're much more likely to shoot in a sitting position off support in a hunting situation. Outside of prone or PRS I don't get it, but that's me.
I haven't shot a howa either but I hear the trigger is great. It's a 2-stage I think.
Savages do wear in but they're never that great. I've been working on mine for a long time and it's now cycling great but it's still got some clank. Too bad about that stock, but I wouldn't buy that model anyway. They slapped an 800 dollar barrel on a gun that otherwise costs like 600 and then put it in a horrendous stock with no bedding. NO BEDDING and they're charging 1500 dollars. I like savages but they're like the Nissan of the gun world, they accidentally make a few great models despite their best efforts. Other than that they're aftermarket platforms. Can't blame you.
Brownings are good, sounds like you're about there.
Look through any glass?
