I did have a Taurus 731 (SS .32 H&R 2" ported) before a burglary and losing about 12 guns.
Do not fire the .32 S&W (short) rounds in a .32 H&R Mag. That was the word I got from both S&W and Taurus. .32 S&W Longs are okay. Firing 32 S&W Longs from a .32 H&R Mag with the soft lead bullet leaves a lot of cleaning to do. Here's what I did to cut down on it...
1. Purchase a bottle of
Tetra gun spray cleaner and
Tetra Bore Conditioner. Also purchase a "Lead Away" cloth (yellow wax-impregnated cloth).
2. Thoroughly clean the revolver. Use gun spray and a good solvent (
Rig #44 or your favorite) and new .32 caliber cleaning brushes. For stubborn lead fouling, cut the Lead Away (LA) cloth into a patch and use this to clean the forcing cone, barrel and chamber mouths where leading builds up. You'll need to use about 1/3 of your cloth to do this. Use the cloth to remove powder rings from the front of the cylinder & muzzle too.
3. Spray the gun clean to remove any residue from the LA cloth, wipe down. Now use the Tetra Bore Conditioner as directed (Shake vigorously!).
Also use the this product in the cylinder chambers with a clean patch.
4. Remove excessive bore conditioner and lubricate the firearm as normal.
5. At the range, use a short cleaning rod and the .32 brush every 25 rounds or so if necessary to keep lead from building up in the cylinders. Otherwise lead can build up in the cylinders to prevent chambering .32 H&R rounds.
6. When you get home you'll find the Tetra conditioner and occasional brushing leaves you with much less work to do in cleaning.
Hope that helps!
