The 300 to 350 are not bad i can shoot about 20 to 30 rounds before it becomes uncomfortable. 700gr is a whole new game. The 500 gr is probably stout but it cant possibly compare to 700 gr. Its the only handgun round i have ever bruised my hand with after 5 rounds. I managed to hit a steel silhouette with it despite a terrible flinch it gave me. The plate was probably 40lbs suspended by chain, and it seriously looked like it would flip over the hanger if I could time a 2nd shot just right.
