dharvey, do you shoot much in the way of comps?
Small bore field is fun or silohette and only use an average plinker, not your most whizz-bang rifle.
Maybe it's time to find a challenge for yourself?
Find a cheapie rifle that isn't renowned especially for it's accuracy.
Like say a 6.5x50 Jap, maybe an old cartridge like 32-20, or for a real challenge the renowned loser rifle, a Mannlicher Carcano.
Then just spend your time training yourself to shoot it well.
Do minimal adjustment, retain the standard furniture, adjust the bedding if it needs it and fix stuff like headspacing, bad sights, etc.
Basically get an average rifle to shoot well, or more accurately you to shoot an average rifle well.
And stick to factory ammo for a real challenge.
Then, if you're tired of it, just sell it on.
It may open you mind though.
Or get into old stuff like 577/450 Martinis and Sniders.
That'll really open your mind!!
