A few posters on other forums tested clear shot, pyro and 777 with the same load, bullet and rifle. The slowest bullet speed/energy was with clear -- the next higher was pyro and 777 was highest. If you're shootin' between 50-75 yards, you should do fine. If it's 75-150 yards, your clear shot will not match pyro or 777 in energy & speed.
As long as you're happy -- that's all that matters.
