357 Combat Magnum, which became known as the Model 19 and its stainless steel counterpart, the Model 66 which arrived in 1971, experienced problems in the forcing cone
Swaging resistance: Force required to swage an obturated bullet down to fit the bore (usually a significant factor only in revolvers, where the bullet swells into the forcing cone
, as it exits the cylinder).
It also does a great job of removing lead from a revolver's forcing cone
Other features include: a receiver machined from a single block of steel, solderless barrel system, a lengthened forcing cone
to reduce recoil, classic game scene engraving and a fancy black walnut stock and forend.
One bullet stuck in the forcing cone
due to a failure to fully ignite the powder.
The chamber area does not show a noticeable step cut to denote where the chamber transitions into the forcing cone
If the chamber is not properly aligned, the bullet will slam into the side of the forcing cone
at the rear of the barrel and will basically be deformed before it gets into the bore.
First, the over-bored portion ahead of the chamber starts getting smaller, and the forcing cone
itself is lengthened.
454 bullets they can become misaligned and not be concentric with the bore when they slam into the barrel's forcing cone
and engage the rifling.
The forcing cone
has been lengthened; the barrel cryogenically treated, polished and ported; the trigger lightened to a nice 3.
And when the crimp fails, bullet noses often extend far enough out of the case the nose of the round may not clear the forcing cone
, effectively locking-up the revolver.
On this particular model, the entire barrel is a forcing cone
producing a significantly better pattern and much more reduced felt recoil, so the gun stays in his face better.
