I use their Gunslinger II pack for PRS and have no complaints so I'm sure the Halftrack would be more than up to the task. One lesson I learned quickly on, was to use folding ammo pouches/binders instead of ammo boxes (at least the plastic kind for reloads). If you're shooting factory ammo in their original boxes, maybe not so much a problem, but the plastic ones for reloading are definitely not ideal for out in the field. The folding ammo pouches/binders also open up a lot more room for you in the pack.
