10mm Underwood Ammo thoughts wanted

[StatesRightist]

Anyone have experience with it?

I bought some 165 gr Gold Dot's from them. However, a question came to my mind later, is 1400 fps above the design criteria for .40/10mm GD's. Will the jacket separate? Thoughts? Anyone know for sure?

Thoughts/comments appreciated!!

Underwood is well thought of.
I have shot his 165 FMJ loads and find them accurate and powerful.
As Gold Dots are a plated bullet process I doubt you will get any seperation, also test do not show any..

First hand experience here; 100% projectile weight-retention, .74" expanded diameter, can't recall the penetration depth but it was substantial. Thumbs up.

Am curious what you guys are shooting these out of? Aftermarket barrels? Stronger recoil springs?
