Broke out my chrono for the first time today. Tried my 2 most accurate loads of cfe223 with 32g varmageddons. Have been doing load development for a while. 31grains averaged 4200 and 31.8grains averaged 4300. Both will do 1/4" at 100 yards. I had big swings in velocity which is what concerns me. Im talking 100 fps difference between min and max. This happened with both loads. I shot another rifle in different caliber with factory ammo and didnt see the swings so it wasnt the chrono i presume. Is this acceptable because we are talking 4000fps and not 2800fps? 100fps deviation seems high but is it all relative? Is this a negative of neck sizing? My full length sizing always seems to produce more consistent neck tensions and ive only neck sized my .204
