New 22 wmr

Just got a savage 93 FV. It's light, good trigger, smooth loading. Grouped on a nickel @ 50 yards out of the box. 2-3" groups @100. The bolt's motion feels like it has potential but as-is it slides freely but locks with resistance. I wouldn't mind a more consistant feeling of mild resistance (machined fit) throughout the motion. More reps should make evrything gel.

I have a design question. There is a small, kinda spherical component dovetailed into the bottom of the heavy barrel. Internally the stock has a small dam that seperates the action area from the barrel channel. On one side of the dam is the forward action screw and the channel side, making contact, is the component in question. LONG STORY SHORT  ...what is it? Never seen anything like it.

 i have a savage mod 93 17hmr sporster  and under the barrel on it the dove tail slot u are talking about is the recoil lug and the recoil lug goes up against the dam u are talking it the stock i am sure when savage did those barrels for the 17 and 22 mag they use the same barrel just cut what riflling  or cal they want in the barrels, sporster barrels and heavey barrels so they can use 2 size barrels for 22 rim fire to 22mag
