That is the reason I shoot boolits that are larger then the bore diameter and do not size them. These do not need to bump up. I think the BFR has rifling lands that are too narrow for cast. Might be a little skidding going on but I have shot them accuratly to 385 meters to hit an 8" gong 2 out of 5 shots. My first 200 meter group was 4-3/4". Can't complain too much. I shoot creedmore, no sandbags and use a red dot that covers 12" at 200 yards. I am not going to worry about a little lead because it wipes right out on a patch.

I would recommend tyring different brands of lead bullets before going back to jacketed. I have not shot the Leadheads, but they may be very hard and you may not be driving them hard enough to prevent leading problems. For the load you are using, a softer bullet may be in order to allow for the base to expand and fill the grooves, thus preventing the gas cutting and associated leading. Also, you may want to try a gas checked bullet as well. I have shot a good many of Dry Creek Bullet Work's bullets and found them to be very satisfactory.

What problems have you had with the XTPs? I shot over a dozen deer with them and not had a but of trouble.

I doubt I'm getting any gas cutting. I am shooting bullets sized .431. Maybe these are too oversized and I should try .429 or .430?

I shot one doe with an XTP behind a stiff charge of H-110. I just was not impressed by the bullets performance. It was the most accurate load I have shot out of this pistol. I like the economics, simplicity, and nostalgia of shooting "Elmer's" bullet, but if I have to go back to jacketed I will.

I leaded up my Redhawk 44 mag one time in a match. To clean the barrel I just shot a full jacketed bullet thru it. And that took the lead out. I heard that there is these copper caps that fit on the end of the lead bullet and cleans the lead as it is shot. They aren't called caps.
