Thank you for the comments fellas. The only real purpose for these types is big game in thick cover and the closest I'm ever gonna get would be a black bear and that dont seem fair.....on the other hand if your gonna hunt 'em on the ground then it's going along.
This gun is about 100 years old and was factory converted about 90-95 years ago, so I'm working up the right load. There is no data for brass, smokeless powder 12 gauge slug loads. The issue is also the wads (no plastic in my guns) anyways I think I have it fairly close now. I'm right around 1580 to 1600 fps now, no signs of pressure either in case dimensions, primer measurements etc.
There is no reloading set-up. no press, dies etc. Old school hand work so here is some pics of my complicated set up.....ya right. The main deal with large bore, straight wall cases is not just the bullet weight but striking area of that bullet.
DC...that squared tube does 2 things....flash suppressor for vision in low light, but also works as an expansion chamber for the muzzle gasses. It flattens out the report to a very dull roar instead of a supersonic "blast".
Don, unkieford....when I pay my dime I want my ride....all of it. Recoil is not really all that bad but thats relative to the shooter. It's some stiffer than hot loaded 45-70-500
Pat, never give that a thought, but hell man ya never know if your gonna get caught in engine block stampeed
Thanks again fellas
rich
forgot to say the first pic ya see different colored primers....use magic markers to designate different charges in different loads ( color code)
