I just had a range session with various .458 bullets and the orange MMP sabots and blackhorn. I have a TC pro hunter.
Loading was super easy. Maybe it is due to the QLA in the TC barrel, but I could do it sitting down and holding the gun upright.
I started at 90 grains and had very good groups with the 300 and 350 grain Hornady FP's and RN's. I switched to Speer 350 FN's and upped the charges to 95, 100, and 105. Groups kept getting bigger. I went back to 90 grains and groups shrank to 1.5 at 100.
According to BH website, 80 grains with a 350 is 1550 FPS and 100 is 1750, so I am assuming 90 grains is right around 1650. I will set up my chrono next time to verify.
I plan on using either the speer 350's or a Kodiak 350 for my upcoming elk hunt here in New Mexico.
