[QUOTE="jasent, post: 777997, member: 28233"] Yes but I dont believe reacting to recoil can change velocity that much. Guess ill have to test this theory. I've always been told recoil starts when the bullet exits the barrel not at ignition. Tho ignition and bullet exiting are only thousandths of a sec apart so.... Also have to remember that chrono's are not perfect and many are only accurate to +/- 5% at 3000fps that can be +15/-15 fps each shot,also if your ammo is sitting in the sun waiting to get shot its warming up as well which will change speeds or if your action is warm or hot and your taking your time making sure your doing your part as they say it may also be warming it up. Combine that with normal +/- of the chrono and that could easily be your 50fps spread. or your factory ammo is just not that constant. I'm no expert! Jmo [/QUOTE]
