[QUOTE="Seth247, post: 1327623, member: 12010"] This and the whisper are near identical. The possible ballistics will be the same. Noveski mentions in their .300 info page that all of their .300/.221 barrels with serial numbers over...29,000 I think...will be safe to use with .300 blackout ammo, and barrels with lower serial numbers will have to be sent in to be checked first. So the two chambers must be nearly identical. And the .300/.221 chamber is just slightly different than the .300 whisper chamber, too avoid and copyright infringements and to allow the use of 5.56 brass in making .300/.221 cartridges. So ballistics for all three must be close to identical. [/QUOTE]
