I have the Caldwell frame rest and a Bulls Bag. Use them both. Mainly for load development. The rifle shoots identically with both. Pros: Frame rest. It's far easier to adjust onto the target. Easy to maintain shot sequence. Can be used as rest when working on rifle. Cons: Bitch to store. Don't want to break it down.
Pros: Bulls bag, or any bag I suppose. Easy to store and lug to the range. Once set up is good. Cons: Bit of a bitch at times to set verticle adjustment, lots of fiddling with bits of wood or magazines to lift or lower. Depends on users circumstances, in my view though, bags are probably the better option as a rest.
