Since i started shooting my X47
308 is just gathering dust
mostly coz x47 is so much easier to shoot kinda like cheating.
308 best suited to light 155 bullets n lets face the bc still sucs compared to 6, 6.5, 7mm bullets.
So in order to have a more usable rig as x47 is a match rifle. So thinking hunting n some light tactical work
So
heres my thinking
After much number crunching thru QL/QT
20" no taper truck axle or something real close

Thats 47" of drift 10mph wind and 23MOA @ 1k
Now what kinda recoil can i expect? thou plan is to run a CAN eventually which will help
What you guys reckon do it or stay 308
