Bullets: semi-jacketed vs soft point

[Thirties]

What is the difference in loading data (if any) between these two Remington 125 grain .357 bullets? For example, would the semi-jacketed be more prone to having the lead separate from the jacket in hot loadings? Also, when would you use one over the other, and why?

the semi-jacketed hollow point

and . . .

the jacketed soft point

As long as the semi-jacket bullet has a the jacket material covering the base there is no problem with the jacket seperating from the core. Most semi jacket rounds have more exposed lead thus,presumably,expand better.

Semi-jacketed refers to the amount of lead exposed in hollowpoint and softpoint designs. So a semi-jacketed design will have lead exposed along some portion of the side of the bullet, while a jacketed hollowpoint will have the jacket extending up to the edge of the hollow cavity. Generally speaking, bullets designed for semi-auto pistols are jacketed and bullets intended for revolvers are semi-jacketed.

Not really an answer to your question, but the danger from the core seperating and leaving the jacket in the barrel is from going to slow, not from hot loads. That's why some books do not list 158 grain jacketed loads for the 38 special.

I'm not sure of your level of understanding so I'm sorry if this is something you already knew.
