i have a full size 1911 springfield in 9mm.
i have dozens of mixed brands ...but they are sorted by brands.
i use cast 125 grain truncated cones powder coated & sized .356 after p.c.
early on this summer i loaded 200 rounds of mixed stamp cartridges... pushed by 3.4 grains of PB powder,and checked all for 1.058 oal.
to further my attempts at shooting consistently .... i checked each of the 200 with a case gauge.
known as the "plunk test" all 200 passed flawlessly.
now for the problem...only 1 in 4 would go into battery and shoot , making for a truly frustrating day.
then i remembered that i have a rock island 22 TCM...that came with a 9mm barrel and spring.
so i took the barrels out of both and started over doing the plunk test on the 2 disassembled gun barrels and the case gauge.
REVELATIONS!
the rock island barrel chambered all 200
the case gauge chambered all 200 easily
but...
with the springfield barrel almost 160 would NOT go fully in.... and the remainder that did, were barely going in but with no room to wiggle.
(some were tight.)
some were bulged from the cast boolit going in pretty much!...yet they chambered into the rock island barrel.
does anyone make a after market barrel for the springfield R.O. that is full size... and chambered closer to sammi spec than what i have? something that is plug and play? (drop in and shoot.)
instead of breaking them all down ....i'll just shoot them out of the rock island.
does anyone have a chamber reamer i can buy? that's slightly bigger than my chamber?
