Started out with a Chrony back around '99 and it still works fine albeit at the home of a friend. Pro Chrono showed up several years back and I have no problem with its performance. I never was one to pursue high velocity with any firearm, preferring precision instead. I was a bit bemused to discover that low velocity spreads were not the Holy Grail. That came to light one day when a 5 fps spread was FAR less precise than 25 fps, this with a .338 Win.
Another surprise came from following the suggestion of a Hodgdon rep who suggested I could fill a .22 K/Hornet case safely with their magical Lil Gun. It was a Ruger #1 and I was amazed to see excellent groups with 40 gr bullets that were topping 3400 fps with something around 13.5 gr of powder. Hey, I didn't need a .222 after all!
Until the primer pockets grew.
They are a useful tool, but not nearly as useful as a functional brain.
John, thanks for the telling, very well done!
