About a year and a half ago I purchased a Savage Axis ii overwatch edition rifle from a pawn shop for about $350. I was looking to get a different rifle and sell this one but this thing just shoots. Ive shot a handful of whitetails, countless wild hogs, coyotes and a female red deer.

I am at the point now where I want to tinker with it and see what improvements I can do; here's my current upgrade plan
-bolt lift kit
-bolt handle
-fluted bolt body
-wood stock
-new optic
-new 22" barrel

But I have a few questions regarding my choices. First and foremost would I gain a significant increase in muzzle velocity going to a 22" barrel over the factory 20", i read somewhere the average fps lost/gained per inch of barrel in a 6.5 creed is around 20fps? Second the fore end of the factory stock isnt flimsy per say but i can push the barrel into the stock, would an oem savage axis ii hardwood stock resolve this? and lastly is there anything I haven't considered that i should look into?
