7 PRC match ammo contents

[BlazerBeam]

Is this 72 grains of magpro? I broke down some of the 7mm PRC match ammo and this was the powder.

Looking at Hornady load data that seams odd for the 180 ELDM. The heaviest load they list for that bullet is 69gr of RL-25.

They list 68.3gr of Magpro for the 175.

 

[BlazerBeam]

I know. That's what threw me off. It was definitely 72 grains of something though. The case had no room in it with the bullet in it, don't know if it was compressed, but it could have been. At any rate there were faint ejector swipes on the brass when I fired it

Looks just like mine, except I had 72.5 grains in the one checked.
I have never used anything that looked like that.

Did you shoot any? Any ejector swipes on the brass? The velocities were pretty consistent for me at right around 2950

 

[8andbait]

No, I don't have my rifle yet.

The 175 ammo had 66.0-66.5 of something that resembled rl26.

The 180 and 175 ammo I tore down had RL26. Duplicating the charge duplicated the velocity and accuracy.

Ryan, any idea what that powder is in the picture?
It's sort of like spheres and discs.

 

[FURMAN]

I have never used a ball powder in a magnum so I can't say. I will say I have pulled down some 300 PRC and some have RL26 others have what appears to be the same as above. The ball powder loads are typically lower charge.

 

[BlazerBeam]

This seemed like a pretty high charge whatever it is. Although 2950 seems pretty much right in line with what they say this ammo would run

I bet it is the new staball powder just released!

Hmmmm…a flattened spherical powder…is mag pro flattened like that or just ball?

What about the very new Winchester HD? A temp stable ball powder for magnums? Or Ramshot LRT? Isn't that one a ball type powder?

Superformance looks like that

From the hodgdon load data for sure my Money is on staball hd. 7prc 175 ablr data.
