Hi everyone. I'm new to posting in the forum, but have enjoy and learned a lot from it already. I'm also what I'd call pre-new to reloading. Trying to make sure I completely understand the basics to the point where I at least won't hurt myself. With that said, here is what I want to be set straight about because I'm pretty sure what theory and imagery in my head is off. I know the 44 Special CL is a 1/10th of and inch shorter than the Mag, also that the maximum pressure of the special is 15,500 psi where as the Mag is 30,000 psi max. For this example I'm going to use the Magtech 44 Special FMJ 240grn 15,50 (44F) VS. Magtech 44 Magnum FMJ 240grn 15,50 (44C). OK, I do know this is unsafe, and and this is a hypothetical situation. Since it seems by the bullet specs I have that the bullets are the same except the CL is shorter on the Special, if you took a unfired 44 Mag factory round and (remember, hypothetically in theory) took a tubing cutter and trimmed the case to 44 Special length and then re-crimped it, would just trimming that case change the pressure and velocity and all that good stuff where it would actually be rated just like the 44 Special factory round? Also, thank you for letting me be a member of this forum.
