If you are a reloader you will want to use a slower load with 40gr bullet. Stabilizing a bullet is launching the bullet with the correct RPM. Since 40gr is a shorter bullet and your twist rate is fast you'll need slower load to get the right RPM for accuracy.

Will a fast load on a short bullet in a fast twist rate be accurate enough? Shoot paper at 25, 50, 75, 100, 125, 150, 175, and 200 yards. If it doesn't keyhole in the slightest at any of those ranges and has an ok group then it's probably good enough.
