300Blackout Testing Chronograph Report

[Mr.Revolverguy]

The Umbrella Corporation was founded in the late 1960s as a major international player in pharmaceutical goods and medical supplies, known for their creation of the T-Virus a powerful mutagen that alters living and recently dead organisms. Wait that’s the Umbrella Corporation from the movie and game series of Resident Evil. The Umbrella Corporation I spent the day on the range with has a totally different doctrine.

“Umbrella Corporation is a research, development, and engineering firm incorporated in 2007 with primary focus on small arms design to include complete weapon systems as well as functional parts and accessories that exceed the expectations of the consumer, provide definitive advantage, value added performance, and no-compromise quality. Ingenuity, innovation, with a dedicated commitment towards perfection defines our philosophy.”




I haven't seen any 150gr Speer's tested so I decided to give them a try with RARR Bolt Action and two custom built AR's

Excellent thanks

This round is addicting to reloaders, I think because of the variability in components that can be used. Everyone I know that shoots this round is a reloader and seem to shoot just to get available brass to reload

i have the rem model 7 modified for aac 300blk and like it and will work up a 150gr nosler BT for it, my load for the 125gr nosler BT is win 296 and it shoots close to rem 120 gr factory. the target was shot at 100yds with a leupold 2x7 scope off a good rest. the lower hole is the 120 rem factory and slightly higher is my reload with reformed 223 cases. the rifle it very light and compact and easy to carry all day in the field. to me the 300blk is not a long range rifle, maybe a 150 yrd deer rifle max. eastbank.
