RE: Sako 75 Hunter woodstock vs A-Bolt SS
That's a tough one. I have experience with both rifles. I currently own two 75's (both with walnut stocks) and I have in the past owned 2 Browning A Bolts. As far as the barrelled action is concerned I prefer the Sako hands down. However, I'm not sure I'd want to sit out in a soaking rain with a walnut stocked rifle.
You could, of course, restock the Sako, but by doing so you'd add another $300 or more to the already substantial price. A McMillan stock would really be nice though.
Another option is a gun cover. There's a product call a Gun Coat or something like that that covers the gun and is intended for use in inclimate weather. I've got one, but so far I've never used it. I wish I could remember the correct name for it. I'll look it up and post it.
