I have worked up prairie dog loads for my 22-250 and 220 swift using Sierra .224 55 grain blitzking bullets. Purchased a box of 500 to load and discovered the profile of the projectiles are different than my original bullets. The length increased by .014, the dimension from base to ogive decreased by .016 and the diameter changed from .2250 to .2235. Has anyone else seen changes like this in Sierra bullets? I would like to get 500 to 1000 bullets like the originals.
