[QUOTE="MSURunner, post: 2633240, member: 102961"] GRT models H1000, 225 ELDM @ 3.850 and a 20" barrel to top out at about 2700 fps before going overpressure. You could probably step it up a bit from there, but you might be pushing it a bit hard to get to your 2800 fps number. FWIW, it models a 300 WM to reach the same velocity at 24", so sticking with the RUM gets your 4" of length savings at the expense of about 15 gn of extra powder. [/QUOTE]
