Soft-point bullet have become available for safe use in tubular magazine rifles. Soft-point bullet A soft-point bullet (SP), also known as a soft-nosed bullet, is a jacketed expanding bullet with a soft metal core enclosed by a stronger metal jacket left open at the forward tip. A soft-point bullet is intended to expand upon striking flesh to cause a wound diameter greater than the bullet diameter. Jacketed soft point bullets are usually abbreviated "JSP" in the ammunition and reloading industry. Lead-alloy bullets used with gunpowder firearms were unsatisfactory at the bullet velocities available from rifles loaded with nitrocellulose propellants like cordite. By
C-rich stability element and U-rich compared to the predominantly C-rich human element. Despite this shift the murine alpha globin mRNA is still as stable due to a complementary change in the specificity of the poly(C)-binding protein. C-rich stability element The C-rich stability element is a short part of a gene sequence important for the proper synthesis of globin and several other human proteins. Differences in the stabilities of individual mRNAs can dramatically affect the overall level of expression for genes. Eukaryotic mRNAs can have half-lives that vary from as short as several minutes to as long as several days. In differentiating human erythroid
