Thanks, Frank. Very good advice for starting out on any project. The barrel/breechplug assembly is already proven. That's why the
inquiry about the strength of the receiver. The action will be getting less of a pressure challenge than normal because of the BP.
The barrel is by PacNor and has the same contour and dimensions as the .50 barrel on the Savage 10MLII. It readily handles the
maximum load pressures (even beyond) of the .45-70, even though the bullets are much lighter, thus faster speeds. Anyone who
has seen the receiver on a 10MLII knows just how massive it is, even to the point of over-engineered. But it is no longer made, NOT
because it is unsafe like many have tried to make it sound, but many other reasons, non-acceptance of smokeless being a major
reason.
Quite a few similar models to the one which I will be making are already out there, using Savage and Rem700 actions. I intend to
come up with one which will be very safe, just as accurate, and cost less than four digits.
Jigger, I am a Savage fan, also. Three VLP's in .22-250, .243 and .25-06. But these, I want to leave them just as they are. Be aware
though, Marlin is out to be just as much a success as Savage this time around with their XL7 and XS7's. Switch barrelling would be
pretty easy with these, too.
Thanks to all for your responses.
