I have a Virginian Dragoon in 45 Colt 7.5" barrel blued barrel and case hardened frame. I've had her for decades now, and have wanted to push it a bit. I have had it checked out and been told they were as strong or stronger than the same vintage Rugers. I do know it weighs more than a buddy of mines 44 Super Blackhawk by several ounces. I loaded up a few 300 gr XTPs with Lilgun, and handled them well. Now, it was five rounds and the start load was 18gr, I dropped to 16.2, for my start. They felt good, and burned very clean. I don't see myself going much if any beyond them. I am considering some light fast bullets, and have some Berry's 200 gr 452 flat noses. There are ZERO warm to hot light loads in 200. I was thinking about taking the Lilgun 225 data (Hornady FTX 26.5gr) and dropping to 20gr and loading a few. Your thoughts and advice? I am limited by two factors, Berry's plated bullets max velocities and my lack of a chronograph.
