Yes, I'm here finally. I've been having a problem with my GBO connection aborting when I try to post my answers. It's been ongoing for a few months, so I just keep trying and when it works, answer everybody I can before the bubble pops!
The bullet you want is available, and I make semiwadcutters for all calibers from 32 to 512. I also offer 3 authentic Keith bullets for 44 and 45, which are the only ones he developed.
Hit me by email LBTisAccuracy@localnet.com and ask for any weight or diameter you want. I'll make it. If it isn't an authentic Keith, it will be a SWC based on his nose form for the 44, and I stamp them LBTK.
A pb is fine in your handy rifle if you don't push them too fast, but a gc will allow you take it to the limit, and the limit will be way over what jacketed will deliver.
That particular bullet, 38 LBTK is a real good killer because it has the same meplat as my FN. So if you like the SWC form, go for it, and be happy. It won't let you down
Real Keith bullets are accurate, yes. But they fall behind any comparitive LBT design, in accuracy, power potential and with most of them in killing punch.
