Ballistic gelatin test results : .32ACP RBCD 37gr 'Totally Fragmenting Soft Point'

[Brass Fetcher]

Special thanks to JK for sponsoring this test.

Bullet exhibited severe yawing at impact (~ 10 degree angle of obliquity with the impact face) and had a point of impact that was 2 inches left and 2.5 inches lower than the point of aim, at 10 feet. The unsymmetrical appearance of the expanded lead section seems to bear out that the bullet nose hit the gelatin at a significant angle.

This is why I chose S&B ball

Thanks for testing.

So much for "totally fragmenting"

I also choose FMJ ball ammo for this caliber.

I remember when RBCD was the total 'shiznit" when they first came out, was supposed to change the nature of SD & military ammunition. Pretty much died-down to nothing after the fanboys lost interest and went on to the next brand of "magic bullet".

I carry Buffalo Bore hardcast 90-grain loads.

I also choose FMJ ball ammo for this caliber.

I agree... 7" of penetration is not enough to make a reliable defensive round. I'll stick with 90gr FMJ's. Thanks for the report.

Perhaps it should be renamed to "Total Crap"?
