Were it I, and with your intended purpose, I'd opt for a Abel table or Tac table of some sort mounted to a tripod with a cheap leveling base and bag on top of the table.
This setup will still work for range/PRS type matches, but is (IMHO) much more versatile and flexible in the field when hunting.
Case in point: Last year while hunting up in MT, I had mine with me. I didn't use it for my shot, since I was shooting off a large round hay bale. Instead, it doubled as a seat (had a tac pillow bungee'ed to the abel table). When my shot was taken (I was shooting suppressed, @275yds) my buddy's girlfriend spotted a nice doe in the far left field (we were overlooking four different fields, in about a 230 degree arc), and so we worked are way around the hay bales, to position where a single row of hay bales came to and end, with the targeted doe, left of the hay bale, about 60 degrees and 255yds out. My buddy's girlfriend is a south paw and short, so trying to shoot over the bale was not viable, but shooting around the right corner of the hay bale for a lefty was a challenge. So, we switched positions, and I slowly eased the tripod/table/bag combo around the corner of the hay bale. After that, we switched positions again, and she slowly eased out from the hay bale, placing her rifle across the bag/tripod and built a really stable kneeling position and took the shot. Boom, dead deer.
My point is, with a pig/hog saddle or even a direct mount, you would be futzing with getting it locked into position. That's movement and time, that in a hunting situation, is not practical or desired. A bag and table on a tripod allows a shooter to ease into position quickly (and quietly), build their position, and shift the rifle efficiently without a lot of movement or time involved.
