I got my FX display about a year ago. I just checked mine and at 75 grains it starts back over at zero. I mainly use my display for velocity. I shoot .30 & .35 Impact M3's. Display is set for 54 grain slugs that I shoot from my .30 cal. I stick it on my .35 (making no changes) and it works great. Both guns are surgically accurate at ranges over 300 yards. You don't need to be grain specific to get accurate fps readings. My Labradar is the same way. The only time projectile weight is critical is when you are figuring energy. Then I use the FX app or a ballistic calculator, I prefer Strelok+. I use my digital display all the time and have had no issues with it what so ever.
