Is this realistic; 45-250 at 1030 fps from standard size autoloader?

I was just looking some loads for 10 mm Auto and found that 200 gr out of 5 full size pistol like S&W 1006, using proper powder, could reach 1150, even 1170 fps. If we scale up 10-200 bullet on .451 that comes to 254 gr, standard weight is 250. Calculating energy for 10-200 at 1150 fps and using the same energy level for 45-250, the result is almost 1030 fps, assuming that pistol and the brass are up to the task. Now, we have quite good hunting load. Since 4506-2 is just scaled up 1006, it should take such load without overstressing it. Do I have it right? Thanks.

What you have proposed would exceed the ballistics of .45 Super using .45 Super brass. I don't believe .45 ACP brass could handle those pressures.

You can get 900 with a 250 in the 1911, I don't know about the smith.
It was very accurate and would do a dear end for end but..........
