The rifle was bought in an estate sale from a widow and the woman said it was shot more than a couple times with success. Please help! Btw my bullets are 11.3 gr full copper and my barrel is 1:5.8
Try H335 or H110 In the Quick load software. And it should get you started.
There was a 12 Eichelberger that used 13.0+ grains of H335 if you can find any data on it.
And also a 12 cooper that used 6 to 7 grains of Win 680 with 10 to 12 grain bullets.
All of the other 10 and 12 caliber cartridges that I know about were Rim Fire cases.
I hope this helps.
