Remington has been shipping subsonic 300 AAC Blackout ammunition in their Express Rifle branding with a fairly high price tag and a relatively low rate of production. Now comes the news that Big Green has shifted production over to their high-volume and lower-price UMC brand of ammunition, offering a 220 grain OTM projectile designed for subsonic flight in a 300 Blackout gun. The rounds are shipping to distributors now, 20 rounds per box, 200 per case, with a projected street price of around $17.99/20 rounds. For comparison, the previous Express Rifle run of ammo was somewhere between $19 and $24 per 20 rounds and disappeared quickly. Look for the UMC to do the same.
