I still have some handloads for the 357Max from my IHMSA days. Did have a ruger wheel gun and a TC single shot for that caliber. The TC allowed the use of a longer bullet because the Ruger made their cylinder a little short. Still both were really fine on the silhouettes out to 200 yards.
Strap cutting with the revolver was an issue, but it would burn in a little and stop long before it actually affected the safety of the gun. Still they pulled the gun from the market. I figure it was just bad press... but as far as I know no one is talking that actually knows the whole truth.
We shot 180 and 200 gr 35 cal round nose rifle bullets. (now they have heavy .357 bullets just for hunting, etc.) The caliber had a really strong recoil in a hand gun, but it also hit really hard, which is what you need in IHMSA shooting. I damaged my elbow at work in '86 and had to switch to rifles, so I have not kept up with the handgun sport since the late 80's.
I sure wish I have kept one of my 357Max guns, they were really special. But since I sold them, I only have my left over hand loads to remember our handgun silhouete days in Texas. Oh well, hind sight......
