Wow thank`s a lot guys for the info keep it coming.I am looking at just running factory loads l mean l will hand load my own rounds here in Australia l use 55gn ADI 2207 powder with Remington 300gn hollow point not sure how quick they are coming out but they are a nice mild load l use them in my Marlin 1895 GBL guide gun.l have always been after a nice double and if l can make my own well awesome l have a great workshop and heaps of goodies , CNC mill etc.
But l am a very cautious person and will do as much research as possible before making any start on such a project.Today l have just received W.Ellis Browns book and l am already reading it so at the moment l will keep my eye out for a good donor shotgun.
My chart says AA2207 is H4198. I would assume you are getting around 2,000fps from the Guide Gun's 18 1/2" bl. 55.0gr. is actually Hodgdon's starting load for the .45/70 lever action rifle data and shows 2,200fps for a 24" barrel, at 27,600cup - which should be a safe load for the weaker actions, altough near the top. 2,200fps with a 300gr. is not a load to sneeze at. It's actually factory for weight and speed for a .405 Winchester.
My brother used just such a load (2,260fps actual, seems to me) with a 300gr. Hornady bullet on a 2 year old bull moose one year - the bullet actually exited the far side leaving a 1 diameter round hole. The lungs were blown up. His rifle was an iron sighted M1874 Sharps in .45 3 1/4".
I suspect if using a 300gr. Nosler, it would work on just about anything, but I usually tend to use heavier bullets.
