Dale, it will only get better.
Those Marlin 917V s will shoot.
I have a 917V and a Savage 17BVSS and both are shooters.
On calm days with a good lot of ammo, it is not too difficult to have three and four shot groups touching or almost touching at 100 yards. For modest priced rimfire rifles, thats pretty darn good.
Below are some average groups with my Marlin and Savage. I have shot some better than these and some worse but, these are about average.
100 yd groups.
