Yes, I have used the following loads. The projectiles are "ready-rolled" hard cast, synthetic coated without gas checks. They are WestCasting brand (local here in Australia).
I use 41gns of AR2207 behind the 500gn for about 1600fps. Good accuracy but probably a bit too hard for pigs, of which I have shot some with (full penetration of a medium size pig with the exit wound size depending on what it hits on the way through). (AR2207 is equivalent to H/IMR4198)
I also use 20gns of Trailboss behind the 405gn for about 1000fps (sub-sonic). Good accuracy and I have shot a rabbit with this load (straight through).
