That's good news; I like it when a plan comes together.
NOW, if you have a .30-06 laying around and really want some grins get one of those chamber adaptors for .32 ACP. When I first tried one in my 1917 I was using some jacketed loads that were loaded back a bit for use in my 1913-vintage Colt 1903. First shot was fine, VERY quiet. Second shot produced no impact on the can I was shooting at, followed by a quiet hissing sound. The nose of the bullet was barely protruding from the muzzle....too much barrel to squeak it all the way out.
I went home and tapped it clear with a cleaning rod, so all was well. I now use the 93 grain Lee cast round nose bullet and a little 231. More quiet than several pellet guns I have fired and surprisingly accurate out to 50' or so.
The sound of the bullet hitting a muddy bank with a PLOP being louder than the shot itself always conjures up a smile.
