Chronograph testing and evaluating a one grain powder charge increase of a cast lead 357 Max load.
16.0 grains of IMR 4227 flies straight and groups well out to about 175 yards from this 10" T/C Contender barrel. At 200 yards, I have seen a small amount of wiggle indicated by the holes in the target. Perhaps a bit more muzzle velocity will help the bullet at long range - I need it to fly well enough to be effective on the 200 yard Rams!
I had previous used the 17.0 charge - I hadn't tested it for velocity or performance at distances over 50 yards.
These shots are all high - I had forgotten that the scope had been dialed to shoot 200 yards! I need to keep better notes.
The bullet is cast from an old single cavity LEE wadcutter mold that I opened up to create a wide meplat semi-wadcutter around 215 to 220 grains.
