I'm not knocking LaserCast, but in my experience you want a cast bullet with a gas check since you are going to push the bullet to max. Take a look at beartooth bullets ecspecially the Pile Driver and the Pile Driver Jr. You can go online and get the load data. These bullets were designed to function in the 1895 Marlins. I also have had good luck with Cast Performance bullets. I have several types of Laser Cast bullets and they shoot great in my light loads for my 1885 Browning and slower velocity loads in my Contender. Check out the load data from Hodgdon as they have loads for IMR and their own powders.
