Re: Need Load Data for .45 using Berry's 230 plated bullets
Lead generally uses more powder than a jacketed bullet to get the same velocity and pressure. this is because of bullet hardness and friction between the bullet and bore. Plated bullets generally are best used with cast lead data, though Berrys advises users to load them over jacketed bullet data. To err on the side of safety no doubt.
TMJ stand for Total Metal Jacket and is the only type of projectile allowed in lead free indoor ranges. FMJ is Full Metal Jacket and is very similar to the TMJ with the exception that FMJ generally has exposed lead at the base. Cast lead is bare cast lead. Loaded with good loads they will all put .45 cal holes in the target.
It takes 43 muscles to frown, 17 to smile, and 3 for proper trigger squeeze.
The latest caliber or gear is no substitute for experience and skill. Rifles and cartridges don't make hits -- shooters do.
