I’ve a 1915 grade 1 1/2 Flues in 12 gauge. I’ve shot it on
2 occasions recently, 50 rounds each time.

Periodically during each of the 2 - 25 rounds the gun
doesn’t want to break open, at least not easily.

I know insufficient or misplaced grease will cause this
and I’m checking that out. But I was wondering if
anyone might have some thoughts on this?

It’s not consistent. It seems to be possibly heat related
as I’ll shoot several rounds and it will all of a sudden
not open or open very hard.

It may do this a couple times then be fine the
rest of the round.

I was thinking maybe the pins not retracting?
But I see no signs of them dragging on the spent
hull base.

There is a small uniform ‘divot’ on the base of the
Extractor, but it’s on each barrel and exactly
uniform on each side and it actually looks to
be there by design.

I’ve had the gun about 8 months only and
The first thing I did was take it to ‘Les’ at
Diamond Gun in Ithaca Ny and he went
completely through it and said he found no issues.

I’m shooting VERY light loads of my own of 7/8 oz
With chamber pressure about 6800 at 1150 fps.


Appreciate any thought or experiences anyone may have
on this.

Thx in advance
