I went to the range today and fired my Mark4/Series 70 Colt. Some of the cases did not fully eject, but turned a full 180 degrees in the ejection port and jammed.
The gun was sufficiently oiled prior to firing. The slide was tightened to the frame by Clark Custom Guns. It has an aftermarket satin nickel finish by Trapper Guns. It also has a Wilson recoil buffer and Wolfe 18 pound spring.
The load is a 200 grain SWC plated bullet with 6.3 grains Unique.
I experienced no such problem when firing PMC hardball ammo.
Since the 6.3 grains Unique is not far from maximum recommended by some manuals, I'm thinking maybe just try a weaker spring.
What say ye?
Thanx in advance.
