I just settled on a load of 67gr of AR2208 behind the 220gr Taipan flat nose.
The only trouble is that I have to seat the projectiles out so far that the base of the projectile only sits halfway down the neck, but I can live with that.
According to my calculations that load should be getting around 2800-2850fps, so it should be a great 250m load for pigs.
At 100m the biggest 3 shot group was 35mm and the smallest was just 23mm, the 5 shot group came in at 36mm so I’m quite happy overall.
The best of all was that where my old 270gr load produced 45ft/lbs of recoil, this one only produces 30ft/lbs. Meaning that after I finished firing 50 rounds from the bench not only did I still have all my fillings but my shoulder was fine as well.
