They can be. I was shooting new 50 cal Encore in a couple of weeks ago and I had things wired down pretty good @ 100 yards. Figured I was good to go. Just for kicks i plopped a comparable load of T7 down the tube and shot a 3 shot group. The group was dead on for elevation and size pretty much from what I'd shot with Pyro the only difference was it was 4" to the left of the Pyro groups. Go figure.
