It always takes awhile for Ruger or any manufacturer to run the numbers thru and get a slot in the production line.
When we first hit them up for the 9.3X74 and made a half day pitch to them, it took over 2 years.
When they came out with the .405 we explained to them that they now had the barrels but needed a reamer in 450/400 to satisfy another market. They didn't believe there was a market. I said I could sell 30 immediately and two others said about the same, ....got a promise to look into the feasibility, .........less than a year later they announced the 450/400!
I expect with Lipsey's push, this run of .303's could be announced maybe this summer. You have to understand that 250 guns is nothing stupendous to Ruger, just more market!! The guys stateside have been waiting for 2 years for another run of .250 Savages that was promised.
I've spoken for 6 of the .303's and in reality expect there'll be lots of orders drop out over the next year leaving maybe another six for myself, ......a better investment than the local bank or GM!!!
