Yes, they are super easy to use. I also discovered that my trigger needs to be lightened a bit and my shooting technique needs to be tweaked - I was pulling a couple of shots as I tightened up on the trigger.
I should have remembered the "squeeze" technique where you only use your trigger finger and thumb to fire the rifle, tightening up in a direct line with the axis of the stock.
I also discovered that wind has a major effect on groups, especially with the light bullets of a .243. When I didn't pay attention to wind speed and direction, my group size quickly doubled.
