Not bad! I'll definitely look into that.

The 1-9 works well with the 55 grain rounds as well as the heavier 69 grains(some barrels will shoot 75 grains some won't, the 1-7 will shoot 75 grains but the 55 grainers aren't as accurate).
What do you prefer and why?

I just saw that, nothing quick about just changing the barrel. Ugh.
