No experience with the hog/boar bombs. I tried the buck bombs very briefly for fun, to me they are just too strong. Even using just a little tiny spray from the can seems to completely overwhelm an area with the scent. The regular liquid or gel Tink's #69 never seemed so overpowering. Might just be me, YMMV. I very rarely use any of the store-bought scents/lures, but do sometimes make use of tarsal glands from the deer we kill.
Either way, good luck with your hog hunt.
