I'm glad that you have found heavy loads that are accurate. However, in some hands this is not the case. I've seen many people that do start to flinch and these are people that have been into shooting for years. I seem to have that problem with every 44 mag that I pick up. Maybe its the idea that is Dirty Harrys favorite caliber or maybe its because the loads were at maximum and I'm not used to a unfamiliar gun.
