Quote: Fred, which barrels did you have the 257 Rob and 6x47 made up from?
Both Barrels were made from 24" 223 bull barrels. The barrel were first machined octagon, then rebored and re-rifled.
That being the case, how much meat is there in the H&R bull barrels?
The reason I ask is because I managed to score some 400 Purdey cases and am tossing up whether or not I could have a rifle rechambered to it.
Here's the shape of the case....a long straight 3" job:
Apparently 400 Purdy shot a .405" cal 230gn lead bullet with a nickel gascheck at 2100fps and was used as a deer cartridge as well as being popular with tiger hunters in India!
As it was chambered in double rifles built on Purdey's shotgun action it had to be loaded down.
Packing only about 1500 ftlbs at 100yds it would not be a load I'd be pleased to face a tiger with.
However Woodleigh makes a good bonded core 230gn jacketted hunting bullet for the 400 Purdey these days and in a modern action even 45,000psi would give it considerable improvement in power.
So, do you think there's any cal chambered by H&R that could be rebored to 400 Purdey.
Actually come to think of it.......what about 450/400?
It's a .408" cal I believe.
