Total metal Jacket bullet
FMJ bullet

It is a conventional lead core FMJ bullet, but developed for accuracy.

With lesser FMJ bullets only heart, lung or shoulder shots should be considered.

If solids or FMJ bullets are used this should not be an issue with regard to small game intended for the table.

Despite the name, a FMJ bullet typically has an exposed lead base, which is not visible in an intact cartridge.

Hence, FMJ bullets impart less tissue damage than non-jacketed bullets that expand.

AP bullets are sometimes less effective on unarmored targets than FMJ bullets are.

Such FMJ bullets are less likely to fragment on impact and are more likely to traverse through a target while imparting less energy.

"Open-base jacketed bullets, such as the .323" 244 grain round-nose FMJ bullets used in the 8x50mmR Mannlicher, will often produce better results but are difficult to obtain.

For FMJ bullets mounted in bottle neck cases, roll crimping is generally not ever used unless a cannelure is present on the bullet, to prevent causing bullet deformation when crimping.

While this can be an advantage, it can also be a disadvantage as an FMJ bullet may pierce completely through a target, leading to less severe wounding, and possibly failing to disable the target.

Likewise bullets which have a higher specific gravity than lead, such as the tungsten core Speer African Grand Slam solids being shorter than conventional FMJ bullets will allow for more powder capacity and therefore a higher velocity.
