The Savage 110 Tactical in 6 Creedmoor has always been pretty hard to find. I think Savage only makes one or two runs a year of them.
Three years ago I got mine about this time of the year. I watched Gunbroker and a couple of on line dealers and there were just none to be had. Then in March they were everywhere on Gunbroker. I bought mine from a dealer in Alabama.
They could be bought from multiple dealers on Gunbroker for maybe six weeks, then they were gone. I got mine and liked it so much that I wanted another one. I watched the internet for most of the summer and then in November every dealer had them again, for a few weeks. I bought another from the same dealer I dealt with before.
The great thing about them is that when I work up a load for one, the other one will usually shoot it just as well or better.
Be patient and watch Gunbroker. And when they do become available, don't hesitate to buy one.
