Would it be possible for you to publish load data in the .460 Rowland? I currently have very good load data for Hornady 200 grain XTP and Hornady 230 grain XTP jacketed .451 bullets. I am in need of load data for the 230 grain HC-FP, 250 grain RNFP, 255 grain HC-FP, and 290 grain HC-FP bullets. Your support will be greatly appreciated!

Notice Factory load with popular 255gr is 1154 FPS that would be my target range in velocity with 250 or 255gr in 460. That will be somewhere between 9.0 and 10.0 grs. If non dangerous game suggest 250 XTP.
Start at 9.0 to 10.0 of Power Pistol and Longshot an cronograph you should be at 1100 plus FPS with 250/255gr and work up as needed. Go past 9.0 you will need a comp.
Notice Factory Load 255gr is 1154 fps.
Yes exactly what I need load data for is the 250gr RNFP or heavier for the higher velocity of the 460 Rowland. Underwood Ammo and Buffalo Bore both sell factory ammo for the 460 Rowland with 255gr hard cast bullets with velocities listed at 1300 fps.
Most HP Bullets at 451” are designed for 45 ACP velocities . At 45 Super and Rowland Velocity strongly suggest bullets for .452 made for 45 Colt such as the 250gr XTP or the 250gr RNFP from Campro .
We have added the caliber and released some load data. Please check if we have what you need. Feedback appreciated To potentially fine tune things
