Re: Sandbag or Bipod
Bipod is more convenient, when shooting from a bag you do not have the issue of inconsistant bipod loading (vertical stringing). With some trigger time and training, you can all but eliminate the stringing.
Now I am talking about your standard folding bipod, not those big-azz sinclair F-class deals.
As for accuracy, its all in the shooter. If you are looking for something for shooting off the bench then either will do, as well as a front rest (rock Jr).
