Where's the forcing cone?

While going over my Spillers, I noticed that neither really has a forcing cone at all. I think they used a chamfering tool on it as the forcing cone. I've read that older guns had this problem, but these are only a couple of years old.
It's not anything I can't quickly remedy...but they should do better than this.

Just a note.

It could be that's an authentic design and/or intended.
Many owners have said that the S&B revolver produces a much louder crack when it's fired compared to the sound of other .36 revolvers.
That's probably how the S&B develops a little more pressure and velocity.
Are you disappointed with its performance?

Interesting. I never noticed that...

...but mine is a Palmetto so I wouldn't really expect attention to detail.

I also realized I haven't yet measured the chambers and bore, nor have I gotten around to benching it for accuracy, so maybe it doesn't matter.

I need to get to work on my punch list.

A chamfered opening IS a forcing cone!

It seems that it spits a bit more from the gap than it should, and a little leading. I'm going to cut a real forcing cone in it and see if it improves accuracy, which is borderline acceptable at this point- why I haven't enjoyed shooting it as much.

A light chamfering is not acceptable as a forcing cone.
I will cut it lightly and report back the results...likely sometime later this week.

In the sense that a chamfered opening shovels the projectile into the bore, then yes, any chamfered opening is a forcing cone.

However, if one considers a forcing cone as a device that performs the function of shaping and sizing the projectile correctly for the bore's geometry, then not all chamfered openings are true forcing cones.

And then you have to consider the term 'throat' and how that relates, or not, to 'chamfered opening' and 'forcing cone'.

At this point, my head hurts and I'm going to bed.
