Belgmart,

Thanks much for the info, The chamber cast was not mine but that of the previous owner. I trust him as he is a skilled machinest. I can cast it my self and post a picture. Looks like I should slug the barrels myself as the previous owner said .452 based on his slug. It does shoot .252 bullets he provided quit well however I will verify. The previous owner built dies including a neck die so I am good in that respect. Also a paper patch bullet mold was started and not finished it is now in route to Pioneer Products to be finished up. I have the Lyman 457132 mould so I can also give them a try. I to am a BP long range shooter so I am familar with BP loading.

I will keep working on it and ask further questions if needed. Thanks much the drawing is excellent.

Best Regards,
CG
