Yes, I shoot at the Howick range in Auckland on a Wednesday night.
It's only 25m, but the ammo I'm trying to improve is for 25m. At 25m top quality match ammo shoots a slightly oval hole from my rifle, maybe 0.30" OD. The junk geco I'm trying to improve shoots around 20mm groups, so it should be pretty obvious if the die makes any difference.
