Expansion Industries etr7 experiences?

[treedoc1]

They are local to me and bought a pound to try out. ($18.50)

9mm S&W MP full size
Loaded Expansion Industries etr7 4.0 grains with 9mm 124gr FMJ Bullets - Concave Base over mixed brass and CCI small pistol primers.

Felt smooth, low recoil, minimal dirty brass, all within paper plate at 15 yards, most in 6" dia grouping. Brass ejected consistently to same location.

Previously only used 3.7 Titegroup on plated 124 gr rn. Wasn't happy with consistent accuracy recoil cleanliness etc.

Any educated guesses on velocity/power factor? I don't have ready access to Chrono. Only have been reloading 1 year. Have stuck to basics 45acp, 45 colt 38 sp, 9mm. with Unique and Titegroup.

Thanks for any thoughts.

Some questions answered on the above link. They give a sort-of loading chart, but it's missing one very important part,,--velocity!

I'm glad it worked out for you, thanks for giving us another source for ammo, and components. And welcome to THR!
