Fore and aft movement isn't going to have much effect of accuracy and it's very common on production guns. Does the bushing move or tilt up or down? Left or right? Does the rear of the barrel lock tight? Push down hard on the rear of the barrel while it's in battery, does it move down any? You should not have any wiggle on either end of the barrel when it is in battery. For accuracy (assuming the barrel is good) the barrel has to lock up snugly in the same exact place every time. Most Springfields right out of the box and bolted into a Ransom Rest will shoot very nice groups. And most of them will shoot very tight groups with only a match bushing fitted to them. See if the sights are tight and solid. The only other problem would be the ammo.
