I plan to start reloading shortly with FMJs for my 7mm-08, subsequently developing a stalking round. One of the bullets I'm looking at for stalking, just because I'm interested, has an unusually thick copper jacket, and the French distributor recommended that I should base loads on those for a "monometallic" bullet. I can't find any for a 150gr bullet in 7mm-08, but how do they differ generally from a standard load? I take it that the lower density means that a longer bullet is required to reach the same weight? 150gr is 150gr whatever metal you make it from so in terms of kinetic energy, it doesn't make any difference, there may be a difference in acceleration however, and therefore a possible pressure problem.
Any ideas on how I would potentially go about following this recommendation? I mean to be safe, I could just start out from the suggested starting load anyway and work my way up in increments, then I would start to see if there are any problems, but I just don't really know what the implications of having a thick-jacketed bullet are.
Thanks for any suggestions!
