Forcing cone angles | Single-Actions - ProBoards
2020年2月3日 · A low angle leade in a revolver should not be cut so deep as to accommodate excessive chamber-to-bore offset of .007 to .015-inch. The low angle must then be cut deep to provide forcing cone with enough root diameter to avoid spitting. Thus, a narrow-angle cone of, say, 5-degrees, works best with minimal chamber offset.
Why 11 degrees (instead of another angle) for forcing cone angle?
2014年12月9日 · Correcting such a bastard cone is necessary to pursue accuracy. Avoid a cure which amplifies the disease. Generally, the forcing is cut with an angle of 5 to 11 degrees. Both angles, along with angles in between, have been used for years, starting years before gun writers ever heard of a forcing cone. ACCURACY must be the arbiter of work done ...
Why 11 degrees (instead of another angle) for forcing cone angle?
2015年3月26日 · Back to the 11-degree forcing cone. Done in the traditional short smooth way, it works. Assume zero chamber-to-bore runout, and a tiny forcing cone is plenty. Cut to a given base diameter, a 5-degree cone is longer than an 11 …

2024年9月18日 · Post by seminolewind onSep 19, 2024 at 8:40am. This is a visual pertaining to the performance of a cup hp bullet in wet newspaper. It expanded more than I expected. These are powder coated .452 bullets fired from a BFR 454 Casull at about 1200 fps into wet newspaper at 12 yards. The large HP was 300 gr, penetrated 10” and retained 162 gr ...

2018年9月3日 · A shallow forcing cone of 5-degree angle, 11-degrees, should do its job without unnecessarily weakening the barrel mouth. It is true, the longer the cylinder, the more velocity develops before the bullet leaps from chamber to bore. The longer cylinder also holds back BARREL MOUTH EROSION somewhat.
Reaming forcing cone worth it? | Single-Actions - ProBoards
2011年10月27日 · Depending upon how the forcing cone is set up right now, reaming the forcing cone (properly) could require setting the barrel back and refacing it as well. CraigC .414 Razorback

2024年7月30日 · The skinners found that the first two had followed the slope of the skull, tunneling through the meat having left small fractures at the impact sight but no real damage. I believe the straight angle of the truncated cone turned the bullet causing it to skid rather than bite. A round nose is very prone to this. A tangential is not as bad.

2024年9月30日 · Thread choke occurs when a barrel is over tightened. It will start to collapse the bore and that causes a restriction right past the forcing cone and sizes the bullet down and as it typically rattles down the barrel. The result is poor accuracy. After machining I will lap the forcing cone and the throat to remove any machine marks.
Forcing cone? | Single-Actions
2023年11月20日 · What makes you think the factory cone isn’t 11-degree? I can’t read the INCLUDED ANGLE of a forcing by looking at it! Nor heard a person say he or she can do so. The forcing cone plays a huge part in REVOLVER ACCURACY, which includes offsets in CHAMBER-to-BORE ALIGNMENT. Although fuzzy, your photo, your forcing cone appears concentric and ...

2017年5月15日 · Not once have I seen named in such a statement the angle of the factory cone. In all probability the factory cone was 11-degrees to start with, as the 11-degree cone is a dinosaur. The problem with the 5-degree cone is not the angle, it is the depth to which these are often cut, leaving the bullet unsupported between exit hole and groove.
