Where that bullet weight (200) and Speer cartridge may come into its own is in a 10mm carbine. My HiPoint (all gun snobs may moan here) is yielding 200 fps increase with 200 gr slugs over my stock G20, 1090 fps v. 1290 fps.

That velocity, obtained with a less than optimal 2400 powder BTW, is a notable increase in performance with the heavy 200 gr slug. The carbine drives a 180gr XTP to 1355 fps, the G20 same load, 1155 fps. I'll add that my loads with 2400, though not the "hot" powder for 10mm, are very consistent and I think I may prefer it for its even, moderate burn rate and sacrifice some velocity, for lower pressure and no bulged cases in the Glock.

How long the HiPoint carbine holds up is anybody's guess, but it sure drives the 200 gr slug with authority. Whether the Speer 200 gr load would yield the same results in a carbine is another guess too.
