I doubt you will get many responses as the day (minutes?) of the 224V has passed. That said, the 224V was "designed" to shoot heavier (>80gr.) 22 bullets in the AR platform to improve ballistics against the wind. (I use the term "designed" loosely as I believe the 224V was designed on a bar napkin close to a TGIF closing time at a bar near the Federal Ammunition HQ.) Shooting only 62 gr. bullets is 1) a waste of the cartridge's potential, and 2) likely to give poor precision as most 224V chamber reamers will leave you with too much bullet jump with a 62gr. bullet. Additionally, the 224V has been demonstrated to be finicky/difficult to precision tune. (Took me 5 powders and six bullets and about 8 months.) The 22 ARC will likely give you far better precision performance with 62 gr. bullets. Although I would go with the 6ARC . . .
BTW - I love my 224V (but would NEVER build another).
