I was shooting down at the CDTSA Milo range (great range if you are in the Calgary area).
I am using the RRS plate and barricade stop and I personally think it makes a big difference. I didn't make a video of it but when using a Reasor Gamechanger the rifle now sits nicely right on the plate. Before with the angled hand rest the rifle could stay on game changer but it had to be on the magazine, now it can stay on the plate.
