I have the itch to buy or build a target rifle.
I have owned plenty of savages before including a super accurate 6mmBR I wish I had kept.

At any rate, now I am thinking about building a target/hunting/varmint rifle, and this is what I am after.

Repeater (I think).
Stock rides the bags well.
Would like to be able to switch from single shot (target) to magazine with a stock change. I know I could just use a follower too and I may do that and stick with one stock.
But if I were to use an F-Class stock for target, I would swap that stock to hunt.

Accuracy in the 6mm BR range. My old setup shot a solid 1/4 moa.
Very low recoil round.
Setup to shoot free recoil target.
26" barrel and not a bull barrel.
Varmints and maybe an occasional hog or deer neck shot out to maybe 300 yards.
Target out to 600 yards.
Would seldom carry too far.

Thinking about a chassis system, but I have never used one.

Would you start with a complete target rifle or a complete varmint rifle or build from scratch ?

I do know that I will want to use an SSS target trigger.
I do know I will use an EGW base.
Not sure about which action, scope or the stock or any accuritizing of the action etc.
