While .22LR will have the same trajectory relative to the rifle bore in any rifle of the same barrel length and ammo, the trajectory relative to line of sight is what really counts.

Typical bolt action rifle will have the front sight much closer to the bore center than those on the M&P15-22 so your 25 meter zero with the two rifles will strike much differently at 50, 75, etc.

The AR15 front sight 2-1/2" above bore means the bullet has to have a trajectory to bring it up 2-1/2" to strike the target where you want -- where your sights are pointed. Only 1/2" above bore with a bolt action only requires a trajectory to bring it up half an inch.

Likewise a telescopic sight towering over the bore in either will be different as well.

Different sight center above bore generates a different trajectory relative to line of sight.
