[QUOTE="davkrat, post: 980595, member: 6452"] Well you really need to decide what you want the gun to do. As Mikecr pointed out likely the most efficient cartridge will be one of the low power bench chamberings. Not really much to write home about if the intended target is larger big game animals. I think you need to look at what bullets have the highest BC and SD then compare the speeds that various cartridges can launch them at. Most likely something in the .260, 6.5mm or 7mm range will be the best bullets on paper. But perhaps a .308 launching 215 gr Berger out of a 32" tube would be more efficient. Honestly I think what you need to do is identify some classic cartridges that fit the bill of what you are likely to use the cartridge for and then start weighing the compromises between more powder/recoil, barrel length, barrel life, minimum velocity/energy at range, etc. Identify which of those compromises you can live with out and which ones you really need. I think you could pretty easily make a little model comparing your wildcat to a standard. You could then weigh the differences plus or minus for the various factors. I honestly think only you can decide what compromises to make with your cartridge. [/QUOTE]
