Having just read a couple threads on synthetic black powder substitutes and T-7 in particular prompted a question I had a few years back. Hodgon doesn't list data for the 500 BPE and I have a nice Reilly double chambered for that cartridge. It has Henry rifling and while I have a Nitro for Black load that shoots exceedingly well I have never been able to come up with a BP load that regulates. I confess that so far I have been loathe to try paper patching which is supposedly where Henry rifling excels. I did contact Hodgon twice those years ago and never received a reply. My question is has anyone tried T-7 in the 500 BPE in an older rifle? If so, your results?
