I'm looking for a load using Unique or Trail Boss and a 305 gr. Matt's Bullets .452 has check. I'd like it to pop out of a 6.5 barrel at about 1100 fps. I'm thinking 10.6-11.0 grains of Unique (which I have) but al so interested in TB loads as it will fill the case a little better. This will be mostly a whitetail/black bear load in Michigan. Thoughts?
Trail Boss gets my gun filthy dirty after only 10 rounds. I use Titegroup for light loads now and it is way cleaner and still very mild recoil. Go to Hodgdon website to see if a published load is shown, and if not call one of their technicians on 800 number and they will give you starting data on grains to use.
Trail Boss is not what you want for 1100 FPS. A case full of it will only get you 900-950FPS, with that bullet choice. Titegroup gives a sharper pressure spike than unique. Question,,,Why not just shoot some 45 Colt ammo?
