NRA Safety Notice e-mail regarding hand loaded ammunition

[amc577]

Seen several incidents of overcharging of cartridges and/or using the wrong powder... guy loaded 40gns of N110 instead of 40 gns of N140... the explosion was spectacular.. never seen a pressure problem with too little powder.. reduced loads using fast shotgun powders are the norm on many ranges and I have never seen a pressure problem.. reduced loads with slow rifle powders might be the problem but nobody seems to understand the problem.

I can see the temptation to use a smaller quantity of a different powder - particularly for plinking or where you need to under-load due to energy limitations at a particular range.

But nonetheless there is a problem and the root cause is known even if the process is not fully understood.

A useful article on the burn system of different powders... Ball and rod powders are more of a problem in reduced loads.. I have experienced problems with reduced loads of 2400, a fine ball powder.
