Nice work.
Looking at the pics, I was trying to figure out how the barrel, any barrel, transfers its force to the stock, and had a quick question.
Please forgive my ignorance as I'm probably missing something here.
On top, it looks like the barrel has a short sleeve (at the firing chamber) held in a small divet, but there are also two large fillets at the rear of the action (next to the safety switch) which takes most of the total brunt force. The barrel is sandwiched to the trigger guard, by pins screwed together, which might also transfer a bit.
On the trigger guard assembly, it looks like it has a large flat section:
This doesn't seem to correspond with the stock:
Please forgive my nativity.
I was curious about the dynamics, and am probably missing something in the pictures.
That area might be completely unrelated to my question.
It's a fascinating process and thanks for sharing.
