In all modesty, I probably know them better than most do. From the outset, I considered them to be sort of an action "kit". While they can be used "as is" the result will be less than satisfactory IMO. I figure it takes close to a half day just to get them cosmetically acceptable.
Functionally, they are variable. They had a heck of a problem with warpage in heat treat which resulted in some pretty crooked actions. I think the remedial work required on some would be beyond what most 'smiths would care to attempt. On one action, which I kept for myself, I started by placing it on a lead block and hitting it with a 3 pound hammer to straighten out the left sidewall.
Still, I built a half dozen rifles on them and thought they came out pretty good. It was easy to knock a couple ounces off the weight and the end result was reasonably good looking.
I have a left handed, six and a half pound 257 Roberts sitting on the rack that worked out very well. The action is super smooth and feeding is flawless. However, I spent a solid eight hours on that action.
The footprint of the action is close enough to a Model 70 that one can fit it into a Model 70 stock without a great deal of difficulty. The bottom metal is ugly but there is plenty of material to work with to make it look better.
If you are interested in a very light short action, you are definitely looking in the wrong place. A standard short Remington would be a far better starting point and a Ti action better yet. Regards, Bill.
