Ditto to treeWhat is your method to combat offhand wobble?
A tree.
If no tree is available obtain a well balanced rifle with a broad butt to avoid flinching & a weight where you can fire repeated shots in matches without getting the wobbles....
My personal solution was big bore Jaegers with swamped barrels averaging 7.5 lbs with traditional fast twist rifling averaging one turn in length of barrel.
That combo required lower powder charges providing superb accuracy in 100 yd. competition & knock down power on big game.
