Bramble,
You have a very nice rifle there, and all credit to you for the work that has been done to create it.
Thanks also for taking the time to show us the build, bit by bit, with your photos and words!
There will be many here who have been following this thread, who will be very keen to hear about your hunt with this rifle.
All the best for your safari, and can't wait to watch the .404 come to life when you get that project started.
