9mm ammo rapport

[Orange_Magnum]

Today I took my solid steel single stack 9mm semi-auto to the gun range to check out my two new ammo purchases: Fiocchi Extrema XTP-HP 147 gr (Cabela's $21.50/50) and Winchester SXZ9 115 gr HP (Bass Pro $15.50/50). The semi-auto was a Star Firestar, 3.7 inches of barrel.

The target was put up 15 yards away, a small ink dot drawn on a white piece of board.

The Fiocchi bullet was full copper jacket over lead. The bullet had a convincing wide, deep cavity and nickel brass. It looked very well put together. It cycled very well and printed plus/minus 1.5 inches around bull's eye. The punch was soft. It wasn't loud. Listed at 310 ft/lbs. I burnt 30 rounds with no problems.

The Winchester bullet also had a convincing wide,deep cavity. The bullet, lead, probably with a full copper jacket, was coated in a grey film that is supposed to make feeding smoother. It fed smoothly too. It's listed at 362 ft/lbs and that was noticeable through snappier recoil and a louder bang. I was very pleased with how it printed: plus/minus 0.75 inches around bull's eye. What I didn't like about it was the cheap brass casing. The primers had a slight variation in size and variation in placement (off center) . I burnt 30 rounds with no problems.

Another ammo that I can recommend is Remington UMC 115 gr ball ammo. About $11/50 at Walmart. It printed plus/minus 0.75 inches around bull's eye and fed reliably with a soft recoil.

I ended up putting the Winchester ammo in the magazine of the gun and the Fiocchi ammo in the spare magazine, in case the Winchester ammo goes bad over time.

All in all a good day at the gun range.

(9mm ammo becomes +p at around 385 ft/lbs, if that helps.)

Rapport?

You developed a friendly, conversant relationship with your ammo?

Copper cose of the Win.? Most, except for say Wolf Steel cases, have
cases made of brass for it's strength with elasticity for resizing if it is
ever reloaded.

You mentioned Ft Lbs, which is derived from bullet weight times
velocity squared. Most times people state velocity and bullet weight,
as Ft Lbs has little to do with the slippery def. of "Stopping power" or
terminal ballistic performance.

You mentioned Ft Lbs, which is derived from bullet weight times
velocity squared.

Convert all figures to metric...

1/2*Mass * Velocity^2 = Kinetic Energy (in Jules I think)

The equation tells us that velocity matters more than weight. V is squared, whereas M is multiplied by 1/2.

Converting to metric that's like saying convert Miles per hour to kilometer per hour... it's still the same speed.

Anyway, ORange Magnum what make model and Bbl. Len. handgun were
you shooting.
