Bruh - I definitely feel for you my mate.
As for the rifle action question… Depending on what funds you have I’d look at the following in ascending order of expense:
Sako TRG22 in 6.5 Creedmoor
Accuracy International AT in 6.5 Creedmoor
Accuracy International AXMC in 6.5 Creedmoor
Another weird option worth looking at:
Desert Tech SRSA2 in 6.5 Creedmoor
You will have better resale with all those rifles compared to a custom if you don’t end up sticking with this or find that you’re shooting ends up being hunting more then shooting at flat ranges and need something lighter to carry.
Calibre I think I’ve made obvious, just get a Creedmoor for simplicity.
Keep the scope you’ve bought.
