Hodgdon's powders provides a starting load for a .45 ACP 230 gr LRN as 4.5 grs Universal with a FPS of 703. This is with an O.A.L. of 1.200"
M.D. Smith provides a starting load of Universal at 4.5 grs with an expected FPS of 703 for the same bullet, but the website does not provide an O.A.L.
I have seen where some have said they used an O.A.L. of 1.260 - 1.265 with good results for the same bullet.
I loaded a starting load of 4.5 grs of Universal under a MBC .45 ACP 230 gr LRN and a O.A.L. of 1.260, which produced a FPS of 608 - nearly 100 FPS less than Hodgdon's. My question is, could that disparity in FPS be caused by the greater Overall Length?
