Getting ready to load for my Martini and will be starting with paperpatched slugs. I have heard of good results and less monkey business with a traditional lubed cast bullet. However the diameters used vary pretty wildly and with the oddness of Henry rifleing i can't just slug it and get a good starting number.
Can I please try some of what works for you? Happy to pay your postage or send some lead.
Looking for 480gr to 510 gr weight and 462 to 472 diameter.
Thanks for your time.
