A very nice rifle and can it shoot.
I run a load of 98 grains of H4350 (AR2209) in my CZ550 behind the same bullets and get 2450 fps. Try the 400grain Woodleigh Hydro as well. Mine cycles both very well and the fire to same point of impact out to 100mts. I have not tried further. If they print to the same point then you have your soft and solids sorted.
I've got a few packages of 400g Hydro's sitting on the reloading table just for that purpose. I think the 410g Weldcores and 400g Hydro's should have me covered for anything I'll be hunting with this rifle. I still have a few rounds loaded with H4350 that I haven't had an opportunity to try yet. How much did you end up decreasing the powder charge for the Hydro's to get same point of impact?
