I still miss my model 660, one of my first centerfires, sold after owning it for roughly 30 years...what was I thinking?
Didn't Remington bring back that action for a brief period, just a couple of years back? It was a target/varmint style gun with a laminate stock. I can't recall the name, but they referred to the action as being from the XP singleshot handgun, which was the same action as the 600-series. In any case, I'm sure you could build it into a cool little gun. Mine was always very accurate. You may have to do some searching to find the bits and pieces you need for it. Wouldn't it be easier just to use a model 7 action instead?
I have a few of these in various calibers, they are a good rifle. You can true and sleeve the action, rebarrel and restock, bed etc. The only drawback is that by the time you are done, you'll have more money into it then a low end custom action. - dan
"But...how many other people you know have a custom 660 out there."
Me. And I've seen at least a dozen others over the years (including a very nicely done Mannlicher stocked 7mm-08 back in the late seventies, which I lusted after but didn't have the money for). They are a good, basic, Remington action. You won't have the accessories available that a 700 will, but if you except that going in, have fun. - dan
