With your 1911-22, do you find that the lead build up issue happens with all ammo or just with the Armscor? Or more so with the Armscor and less with others? Vice versa?
More so lately with the Armscor which is strange because they are copper coated. Could it be copper build up? It looks more like grey material on the patch.
I took the MB off the 6.5 CM and installed the Limbsaver. The Magnetospeed barely fits under it. Shouldn't be a problem because the instructions say to keep the muzzle at least 1/4" from the V-block. I'll probably also try the LS behind the chrono. I have 4 of the Noslers left and 45 of the Hornadys left. I found more HM bullets at Arm or Ally but holding out for free shipping at Brownells. Plus last time I ordered bullets from AOA, it took over a month to arrive so hesitant to try it again.
I used the last of the lead test kit on the magnetospeed and was heavily contaminated with lead but easy to clean off.
