I don't really need practice rounds, nor do I have a problem with lots of recoil. I shot a .44 magnum revolver before... I expected more kick... it was a bit disappointing... after shooting it I realized I could shoot it one handed.
Got it, no to compensation... Cor-bon hunting rounds are rather expensive... and winchester makes supreme for .45, but only super-x for 10mm. The cor-bon 45COLT/MAG +P -- 300gr JSP is stronger than any 10mm round I ever found... can you use those in a G21?
Also, since we're on rounds... for hunting is faster more important than bullet weight? Remington
