[QUOTE="Tripodmvr7, post: 1982199, member: 115545"] I have paid a visit to our local PMP ammo producer and they reload with equipment that dates from the second world war. These machines loaded many millions of 303 rounds for the war effort. As they worked an eight hour day shift only, their method was to load up a few cartridges (early in the morning) with incremental loads and shoot them to confirm accuracy. Once they had experimentally determined the load it was set on the machines and the loading of ammo for the day commenced. Their quality standards do not match American ammo companies, but for hunting purposes this was sufficient. They also produced a lot of 5.56 and 7.62x51 ammo. I have for many years done Quick Load calculations with a plus 90% success rate and have done a theoretical exercise with a 303 load that calculates as on a node for a 24 inch barrel. If I reduce the barrel length to 20 inches the speed is lower, but it again meets the barrel time that is on another node. This explains why the ammo performs reasonably to very well in different firearms. [/QUOTE]
