Speeds Feeds and Ballistics — Norma 10MM, Jesse James and Underwood

| April 1, 2019 | 1 Comments

30 Year old Norma 10MM was test across the chronograp and into ballistics gel. Thanks to Overkill338 I was able to get my hands on some. Originally this ammo was spec’d at 1400fps as seen in this video 30 years of storage had a negative effect on velocity.

I also compared the new comer Jesse James 10MM against long time 10MM kings of Underwood.

    Yes NORMA was loaded slightly higher back in the very early days, later production was slightly down loaded. Early 200 grain at 1200+ fps and 170 grain at 1400 fps.

    The Jesse James 180 grain bullet is more than likely a ZERO brand bullet as sold by Roze Dist. http://www.rozedist.com/mm5/merchant.mvc?Screen=PROD&Store_Code=RZD&Product_Code=R134-A&Category_Code=ZBJ-40SW

    Underwood ammo is what it is, great high energy and impulse performance. Those SPEER Gold Dots being a bonded bullet are fantastic performers!
    Thank you Mr. Revolver Guy and Overkill338.
