[QUOTE="elkaholic, post: 953191, member: 13833"] I think a comarison between the two would shake out like this. Velocity would pretty much be a wash. Because of the case design, very little capacity was lost (maybe a grain or two) and the shorter SS case is a little more efficient. Beyond that, I think all of the advantages would go to the SS except for ease of forming and the SS is not that difficult. Some of the advantages are, it will fit and cycle through a standard magazine, the barrel life should be a little better because of the case design having a sharper shoulder and longer neck, the longer neck is a potential accuracy plus, and I have seen NO significant case stretching which requires trimming. Turn around on a buil is fast because the reamer and dies are available on demand. As far as pressures with RL33 go, I can reach higher velocity with it than other powders with LESS pressure and running equal pressure, re velocity. For example, max charge of retumbo would fall nearly 100' short of RL 33 and you gain about 40' per grain, . . In other words, you could load two grains less than max with the RL 33 and still equal or exceed Retmbo....Rich [/QUOTE]
