Yes, i too was surprised at how high them bullet flew when the load was changed from 100 to 140 grain.
There were only 3 vial of 140g loads left from yesterday. All shots using the 240g bullet were using 100g loads.
It is kinda too bad we can only use 1X scope here during muzzle loader season(s). Otherwise, it would be kinda fun to try either a 300g XTP or Deep Curl pushed by 140g of Blackhorn. However, i guess if we could use magnified optic for muzzle loader hunting, i would try smokeless to reduce the recoil some, and to minimize clean-up. My guess is them 300g bullet pushed by 140g Blackhorn, should fly out at 2200 fps or so, and be supersonic out to 350 yard or more. After the fella moves his cows out of where i can get a 370 yard shot, i may see what happens using 140g charges behind 300g bullet, at them 350+ ranges. Whatever..............
If you go shoot with Chet, and i know about it, i will join you, if i am welcome.
