I have a Remington 700 LSS in 270 Winchester. It has a sporter weight 24" barrel. I plan to replace the stock and use it primarily for prone shooting in fields. I am looking at 2 different stocks, the sporter thumbhole or the vertical grip which looks like an A5. The vertical grip will have a large gap between it and the barrel. If I ever rebarrel I'm not sure I would go with a full bull to take advantage of the wide barrel channel. I've only owned one thumbhole and it was nice to shoot, but I have not had my hands on the HS version. Like I said earlier, I'll probably use it for prone shooting, but I may carry it through the woods as well. Which would you choose and why?
