I don't believe it's actually Henry either but from his description it certainly sounds "Henry-esque". Kinda like my 9.3 X 75R except mine has what I'm going to call double lands....that is two lands fairly close together. They are thin and appear sharp.
As far as shooting jacketed bullets in his rifle I believe he should if he isn't going to paper patch. That style of rifling, in my experience, likes dead soft jacketed bullets, such as the Hawk I mentioned, a lot better than it likes cast, naked, grooved and lubed bullets unless they are cast of almost straight lino, that is to say very hard. The BHN of lino is 22 and dead soft annealed copper is 25....precious little difference. That has been my experience with the two rifles I now own and others owned in the past that had "Henry-esque" rifling, (well, the Reilly definitely has Henry rifling but then it's British). You no doubt remember all the wailing, cussing, moaning and gnashing of teeth I went through with my T & S drilling and cast bullets with smokeless powder, straight black powder and duplexed black & smokeless. It shoots 34 grs. of IMR 3031 and the Hornady 200 gr., .358 jacketed round nose bullet into less than an inch at 50 yards off a bench, open sights, cooled about 15 minutes between shots. I have yet to try the Hawk bullet I bought but I expect excellent results from them as well. Now, none of that is to be taken as the last word as I am certainly no authority. That is just my experience. We've all been fooling around with firearms enough to now that each one is an entity unto itself.
If sized and patched correctly I don't believe it will cut the patch. I believe that has been the experience of my friends who shoot PP in British doubles with Henry rifling. It definitely unwraps it better than Enfield style rifling. I wish I knew more about PP bullets but I just don't want to do it. I dink with enough stuff without adding another step....lol!
